Are Athiest The Most Intelligent People? ?Only when it comes to the spelling of atheist. No, atheists are not necessarily more intelligent than theists. |
Deep Sight:Quick response: There's not much logic involved in your argument. Further, if findings so far in our solar system and galaxy are an indication of the universe as a whole, then it would be more likely that life is a rarity. There's also a simpler explanation for the will to life: it is those species that strive to survive that get to survive. Those species that didn't want to or could not try to live didn't pass that on. Evolution at work. Nature does have a balance between life and death. |
nuclearboy:Or better still, a Christian scientist trying to ground a Biblical report in a plausible physical explanation. IIRC, Carl Drews, the lead scientist on this, is a Christian. By the way, at the risk of pointing out the obvious, you guys realise that what Drews and his team are saying is more or less "this is a possible way what was reported in the Bible could have happened". |
Odunnu:It depends on the form and the options provided, but atheist, no religion, or other |
Open atheist, but I don't bring it up unless someone asks me or cares about it. It's just another (sometimes small) facet of the whole that is me, that I don't need to wear it on my sleeves. vescucci:I think of atheism more as a lack of or non-belief in the existence of gods. That wouldn't necessarily preclude belief in other things. Atheist assemblies already exist. Humanism is also an atheistic religion that features meetings, etc. |
Minor quibble:It's Hawking, not Hawkings. The book sounds interesting and, while I agree with Hawking's view that gods are an unnecessary addition to the explanation of the universe's workings, I'm interested in reading the book to see what it offers. Hopefully it's a cracking read. |
OLAADEGBU:Um, didn't Marx pen "The Paper Maiden" when he was in twenties? This is typical of several of the quotes that have appeared in this thread. If I remember correctly there's even a quote that is attributed to an atheist, and called his last words that is different from another attributed to the same person in another thread. |
ogoamaka99:Define spiritually ignorant. Anyway, I have often found that atheists are generally more versed on the Bible than many Christians. Of course I'm speaking in generalities here, but the point stands. But to me i refuse to accept that they are atheist but rather are religious ignoramous who has lost their mind and so could not reason well again. I said this because if they are truly atheist ,then what on earth are they doing in religion section of this forum.?What are atheists doing in a religious forum? Discussing, debating, learning and teaching. You don't need to be a theist to feel the urge to learn new things and correct mistakes made by some theists. My dictionary defines atheist as one who denies the existence of GOD, and the Bible and the Koran are books of religion written about GOD or ALLAH. If actually they are atheist , [/color]how come they claim to have great insight in Biblical and religion topics being discussed in the forum?.[color=Black]They have insights into those books because they are able read and understand said books. Realising that there are no gods does not mean that the books attributed to certain gods also go into non-existence. Don't mistake a book for the gods mentioned in the book. A true atheist does not have any thing to do with religion yet these group are the greatest noise makers in this forum.They post religion articles and equally reply to religion posts.Nonsense. Thanks for being the jerk who thinks he/she can define or describe what atheists are supposed to do and not do. [snip] Is it not logically an irony for someone who claim that there is no deity or GOD and yet still claim and pose as having great insight and understanding of religious matters".Alternatively, you may not know what logically means. |
(7) Where did the human emotions, such as love, hate, and jealousy come from?Those emotions evolved and are emergent properties of chemical and nervous interactions. Incidentally, those emotions - love, hate and jealousy - are not only found in humans, but also seen in a vast array of other animals. (8. What are the odds that the evolutionary process, proceeding by random changes, would produce human beings, plus millions of species of animals, birds, fish, and insects, all with symmetrical features, i.e., one side being a mirror image of the other? We take symmetry in all these creatures for granted, but is that a reasonable outcome for a random process?The odds are pretty god when selection is factored in. Symmetry is a reasonable outcome of selection. (9) What are the odds that of the millions of species of animals, birds, fish, and insects, a male of each species developed at the same time and in the same place as a female of the same species, so that the species could propagate?Populations evolve, not individuals. It might also be of interest to note that there are species that may be representative of the variety that eventually led to division by sexes. To wit, there are species that are asexual, with no male or female components. There are also species whose members have both male and female organs. And finally those with interchangeable sexes. These examples give us a small snippet of potential stages prior to a selection for somewhat separate sexes. Further, the incidence of sexual ambiguity and mixing of sexual component show that animals, including humans, still possess the traces the evolution of sexes. (10) Why are there 2 sexes anyhow? This is not foreordained in the evolutionary framework. Is there some sort of plan here?What do you mean by "foreordained in the evolutionary framework"? Nothing is foreordained. Why are there two sexes? Probably because it maximises procreation with just enough genetic diversity. (11) If the first generation of mating species didn't have parents, how did the mating pair get to that point anyhow? Isn't evolution supposed to progress when an offspring of a mating pair has a beneficial mutation?Well this is just nonsense. Mating occurred in conjunction with asexual reproduction. No, evolution isn't supposed to progress "when an offspring of a mating pair has a beneficial mutation". Instead, evolution may occur when a population experiences enough changes in their allele frequency so as to be a different species from the one to which it originally belonged. The incidence of mutations is not reserved only for sexual reproduction, but may also happen in asexual reproduction. (12) How did the heart, lungs, brain, stomach, veins, blood, kidneys, etc. develop in the first animal by slow, minute steps and the animal survive while these changes were occurring?OLAADEGBU, the fact that the person from whom you've copy/pasted shows they are just as misinformed about evolution (as if the nonsense on elements, gravity, etc, wasn't an obvious indication) underlies why it's important to learn about a concept or science theory properly before trying to attack it. What you've done is no different from a Muslim learning about Christianity solely from a source that isn't even aware of the Bible. To answer the question, once again, populations evolve, not individuals. Further, like the example of sexes, one may observe potential intermediate stages of those organs in other animals for whom they are sufficient in a primal to secondary state. Need I go on? I'm bored of this already. If you want pick two of the questions you feel are the hardest to answer or the most hard hitting, and I'll attempt to respond to them. I'm not going on a rebut every part of a copy/paste mission. |
OLAADEGBU:Colour me surprised: OLAADEGBU, a poster clueless about science copy/pastes a bottom barrel of inanity from someone just as ignorant as he is of the subject being discussed. Okay, on this occasion I'll limit my responses to only those questions that deal with theory of evolution. One of the most-powerful pieces of evidence against evolution is the fossil record. If evolution occurred by slow, minute changes in living creatures, there would be thousands of times more transitional forms of these creatures in the fossil beds than complete forms. Since the billions of fossils that have been found are all complete forms, the obvious conclusion is: Evolution has never occurred! Though evolutionists have stated that there are many transitional forms, this is simply not true. What evolutionists claim to be transitional forms all have fully functional parts. A true transitional form would have non-functioning parts or appendages, such as the nub of a leg or wing.This is absolutely wrong. There are many fossils of transitional organisms, but there's no need to exaggerate the number of fossils that have been found. Of course transitionals have fully functioning parts - to expect otherwise is to create a strawman. What, instead, is expected of transitionals is that they are clearly representative of species that are between two distinct classes. The transitional animals, for instance, tend to possess features that indicate the shared ancestry between the two classes The dinosaur-aves transitionals are good examples, where in archeopteryx, for instance, one may note that despite having well known characteristics associated with modern aves, it also had classical dinosaurian traits that include: " 1. The lack of a bill 2. The presence of socketed teeth 3. Nostrils far forward on the snout 4. The vertebrae of the trunk are free, not fused 5. The presence of abdominal ribs 6. The ribs do not articulate with the sternum 7. A shoulder joint that faces downward 8. A mobile wrist, unfused digits and claws 9. A long tail with free vertebrae 10. Solid bones" (1) Where are the trillions of fossils of such true transitional forms?Like I pointed out above, there's no need to exaggerate the number of fossils that have been found. We haven't found a billion fossils, let alone a trillion fossilised transitional species. However, it is false to claim that there is an absence of transitionals. I have given some examples above. And as for the issue of kinds, if mouse and rat are the same kind, then humans and chimps have more of a case of being the same kind. _________________________________________________ I will continue tomorrow from question 7, which is the next question that deals with the evolution. |
OLAADEGBU:What is UDI? What apostle? Um, so, what are Sinosauropteryx and Caudipteryx zoui? Two examples I gave you in the thread you thankfully dug up. Are you saying they are birds? Show me where you answered the question or forever remain silent. But I am impressed that you took your time to check out the good person test.The question and similar ones to it have been answered every time it is pointed out that evolution is change in allele frequencies of a population. You've made similar strawmen and they've been shot down at every turn. All these diversionary tactics would not work, answer the question I asked and stop beating about the bush.Um, I answered the question: populations evolve, not individuals. Let me use an analogy to help you understand what's going on here. Imagine I ask you to explain why Mohamme.d was the son of the Christian god, and why he died for the sins of the Christian people. Further, I state that if you don't acknowledge mohammed as god then you've misunderstood the Bible and Christianity. Even worse, I then claim that no Christian has ever been able to answer my questions. Do you understand how simply pointing out where my strawman has gotten it wrong is not a diversion but a valid response? What question did you ask me that I did not answer? If you've forgotten let me direct you to the thread: https://www.nairaland.com/nigeria?topic=304357.0Carry on reading the thread and see how there was still no notable difference between dinosaurs and birds. A process whereby traits become encoded in the genome of a population and may lead to new species. Like I pointed out, mutation may occur by chance, but selections has a tendency to remove the element of chance. The clue is in what the word selection means.While this question follows the same tack of misunderstanding evolution, I wanted to point out that the evolution of a new species wouldn't have been by chance. While mutations occur by chance, selection removes that element of chance. Thus, new species of dinosaur will have undergone natural or/and sexual selection.Here you go again, answer the question I asked if your evolution is not by chance then what is it? Mutations are just like you make photo copies, would the copies be as good as the originals, would it be better or worse?Almost. Mutations are copying errors. This means that there are occasional changes in the copy from the original, and those changes may be positive or negative. The genetic mutations can either cause loss of information or gain of new information but all observed mutations are in the category of loss of information.No. There have been a good number of examples of new information gained. I'm sure you've seen the example of the nylon consuming bug. Another would be the incidence of the Apo-AIm mutation in a certain population of humans. If a beetle loses the information to make a wing on a windy island, the mutation is beneficial because the beetle doesn't get blown out to the sea and killed. Genetically, the mutation caused a loss of information but was helpful to the beetle. What your fairytale teaches you is that the goo-you-via-the-zoo evolution over million of years by natural causes, and that single-celled life form gave rise to more advanced life forms. In other words, what you want us to believe is that over millions and billions of years, increases in information caused by mutation and natural selection developed all the life forms we have today.So information, as you understand it, refers to the way genes in a certain species are expressed? And loss of information means those genes expressing themselves in a way that causes a vestigial trait? Gaining information would then be the opposite? Yes? For single celled organisms like an amoeba to evolve into something like a dinosaur, new information would need to develop over time that would code for ears, legs, eyes, and so on. If an amoeba were to make a change like this, the DNA would need to mutate new information. This increase of new information would need to continue in order for the kidneys, lungs, heart, brain and so on to develop.And we have been able to understand how those organs may have evolved in different species, with the eyes being a prime example of a trait that has evolved in several independent ways in different organisms. What, exactly, prevents species evolving those organs? By the way, an amoeba is just as evolved, relatively speaking, as "complex" organisms. If you are sincere you will realise that theses cells don't contain information for working heart, lungs or eyes and the DNA added would be useless and would only be more of an obstacle than a help.You're right the cells of amoebas don't contain the inherent information for a heart, etc, but the genomes of multicellular organisms can, as a result of mutations, produce those traits based on how they express themselves. There has to be billions of information-gaining mutations for evolution to be true but the fact is that we don't observe this in nature as your apostle admitted, what we see is organisms losing information.Wrong. I don't know this supposed apostle of whom you speak. How you say it then adds up to a gain is what you have to explain to us.Polyploidy. I believe that I just answered you question even though you didn't answer mine and I have a few others to ask you.Sorry, but what was your definition of biological evolution, again? Look, like I keep telling rather than copy/pasting reams of things in the hope that people get too bogged down so you can somehow claim a bizarre moral victory or something, pick a couple that you think are the best arguments or questions. |
OLAADEGBU:Define information. You know some dinosaurs had feathers too, right? OLAADEGBU:Well that's just a blatant lie. Maybe it's time you took the "Way of the Master: are you a good person" test. We have heard your cock and bull stories of how the dinosaur evolved into a bird, can you tell us the gender of the first bird that evolved? Was it male or female? Let's say it was a male. How did it produce offspring without a mate? If a female evolved, why did it evolve with a different reproductive organ? Was it gay or an hermaphrodite?Um, populations evolve, not individuals. Your questions in this section are moot because it relies on a misunderstanding of the evolution of species. Hey, I remember a question I asked you ages ago, that you didn't answer: what's the difference between dinosaurs and birds? Did it evolve by chance, or did it evolve because it had the premonition that it was going to be needed by the male species?While this question follows the same tack of misunderstanding evolution, I wanted to point out that the evolution of a new species wouldn't have been by chance. While mutations occur by chance, selection removes that element of chance. Thus, new species of dinosaur will have undergone natural or/and sexual selection. How did it know what needed to be evolved if its brain hadn't yet evolved? Did the bird breathe? Did it breathe before it developed lungs? How did it do this? Why did it evolve lungs if it was happily surviving without them? Did the bird have a mouth? How did it eat before it had evolved a mouth? Where did the mouth send the food before the stomach evolved? How did the bird have energy if it did not eat because it didn't yet have a mouth? How did the bird see what there was to eat before its eyes evolved?All dinosaurs had/have brains, breathe, eat/ate with mouths and had eyes. I don't think you thought your questions to baffle "evolutionists" all the way through. I get the impression you don't understand even the basics of the theory. What's your definition of biological evolution? |
alienYOUTH:Wrong. Like thehomer noted, Kepler and Newton didn't need atomic theory to work out the movements of planetary bodies. While Galileo also used observation and analysis to get a grasp on concepts related to planetary movement. Ad Huygens to the mix and you get yet another physicist that worked on astronomy without recourse to the atomic theory. In fact, maybe you can explain why you think one has to understand the movement of particles to understand the movement of planetary bodies? Of course, one is also not ignoring the fact that it's fallacious to suggest that watching the actions of humans necessarily validates the existence of cognizant gods. To claim that our existence in this realm emanates from random occurrences in time, and not intelligent design, is a great insult.Why? To whom is it an insult? Bringing this evolution thingy down to earth , its like claiming, according to the "Infinite monkey theorem", that "Given enough time, a hypothetical chimpanzee typing at random would, as part of its output, almost surely produce all of Shakespeare's plays". This statement even simplifies the situation because the Chimpanzee and Computer would need time to evolve in the first place. You honestly do not need proof to know the answer to that.Not quite. It's more like stating that given enough monkeys and a series of filters that help in selection of the right words from the different monkeys, a book comparable to Shakespeare's (thus eliminating the suggestion that one of Shakespeare's works was the goal of the endeavour) will be produced. And, no, when using an analogy, the "Chimpanzee and Computer" don't need to have evolved. An analogy is an analogy that is an analogy. My previous post advanced the thought that the Cellphone, Computer, and Airplane did not just evolve out of nothingness, they were deliberately fashioned out of the creativity and intelligence of man. These objects now further Evolved through time to what we have today, mind you not randomly, but still with the input of the Creators. This brings to the fore that Evolution is an offshoot of Creation.None of those things are biological. They are not comparable to biological evolution in the way you want them to. No, evolution is not an offshoot of Creation. Likewise on the grand and more complex scale, the world and all the complexities involved could not possibly have just "Happened" without intelligent input, it cant even continue to exist without sustained intelligence.Again, why? Why couldn't it have just "happened" without intelligent input? Maybe you can explain without recourse to a strawman? The evolution theory, i believe, is a very lazy and selfish thought processThe theory of evolution, from its inception, between Darwin and Wallace, has been anything but a lazy or selfish thought process. The amount of work put into understanding the origins and changes of and in species is staggering. Further, the amount of good and end-products that have helped humanity in general as a result of the theory of evolution cannot be underestimated. attributing existence to chance; we all know there is no meaningful reaction without a deliberate action,Radioactive decay and the Casimir effect beg to differ. Creationism/Intelligent design is more proactive and accommodating approach to life. The mere fact the creator hasn't come out to defend his position does not debunk His existence.Really? You think the idea of an intelligent designer/ creator putting parts and organs in inconvenient places, while also allowing so many species to go extinct is more proactive and a more accommodating approach to life? As for the supposed creator not coming out to defend her position, maybe it's right to state there just isn't one? Extraordinary claims require extraordinary evidence, after all. The Evolutionist could just as well sit around while the next iphone evolves into their hands.Or could as well realise that you've created a strawman again. |
OLAADEGBU:https://img215.imageshack.us/img215/2158/creaevo.gif |
Jenwitemi:Is the process of evolution of evolution and act of creation? No. Creation - particularly the one with a capital "C" - implies the hand or input of an external being. And while evolution isn't mutually exclusive with creation or planning by a being, it muddles things up when the terms are used interchangeably or as a subset of the other. By the way, I have consistently used Creationism (big "C" when referring to the idea that everything, including species, were created by a god. Creationism is an accepted term and has its specific meaning when used in discussions of this kind.Your arguments with biblethumpers are just about the processes of creation and not the act of creation itself, which to me, is a sheer waste of time. Whether the universe came about through natural processes, or through some dude who waved a magic wand and went, "bippity boppity boo", it still does not remove the fact that all are just creation theories and nothing more.Doesn't it? I suppose the act of discovery is its own reward, then. |
Jenwitemi:Again, no it hasn't become a dogma. It is still up for falsification and many scientists have and do argue several aspects attached to the theory of evolution without being ostracised. If the earth was not created, how come it is in existence then? I don't get your point here. Whatever is in existence is created. Maybe you need to be more specific here. Are you talking about the very act of creation itself, or just a version of it, like the biblical creationism?Like I stated earlier, it is an utterance to claim that the earth was created. The same applies to the statement "[w]hatever is in existence is created". It is my opinion that the natural processes that led to the formation of the earth was unguided, not needing the input of any gods. Biblical creationism can never be scientifically proven or substantiated because it is in the realm of mythology, a kind of mythological poetry. Nobody should even try doing it because it can't be done.I agree. But creationism itself, on the other hand, can only be scientifically theorized and the theory of evolution is just one of those theories, and it remains exactly that, a theory. How the universe came to be is still being researched at the moment. We still know very little. Folks(theists and atheists alike) should stop acting as if they have the answer.Not quite. Creationism is different beast from the theory of evolution. Is there a particular reason you emphasised theory? A theory in science is extremely useful and highly regarded. I agree that there are still more to be learnt regarding the origins of the universe, but that's a different topic. |
noetic16:It's a loss for the "teach Creationism as science" crowd. 1. The plaintiff makes an ambiguous case and calls "faith" as though it were "science". The judge logically throws out the case, based on the submissions of both sides. which is the rational thing to do here.Being that ICR - and many Creationists - have continually made claims that Creationism is equatable to the theory of evolution and has evidence on its side, to the extent they wanted to offer a masters, the ruling is just one more legal strut that belies the claims of Creationists. 2. does this case rubbish the case for creationism? Absolutely not. The only problem here was the manner the in which the plaintiff presented its case. . .by stating facts and labelling them as science. it is a FACT that the earth was created, but to state this as a scientific notion, without making necessary scientific evidence inspired submissions is to declare faith.No. The ruling and the decision of the board does rubbish the case for Creationism, as it accurately points out that the study of Creationism (especially as presented by ICR) is dogmatic and lacking in concrete evidence to support its position. It was going to be taught as a science (hence the masters in science education). And of course, you already know that the theory of evolution is not a dogma. Also, no it is not a fact that the earth was created. Instead, it's a claim that the earth was created. In any case, do you want to present the scientific case for Creationism? In your own words. 3. There are scientific evidences and notions that support creationism. These are pretty obvious, the major difference lies in the acceptance or rejection of these evidences. The objective exploration of the science behind creationism presents plausible evidences for a created universe, while the objective exploration of the evolution case reveals holes and gaps that are scientifically, logically and intellectually inexplicable.Well, this will be as good a time as any for you to present - again, preferably in your own words - one or two of those "scientific evidences and notions that support creationism" for scrutiny. So far you've made utterances. 4. is evolution a science on its own?The theory of evolution is scientific. |
alienYOUTH:I suspect the problem may be that many of those Creationists realise that holding an untenable position can't be defended by faith alone, especially when the position is used in Christian apologetics. Besides, anyone who thinks the world "evolved" after a big bang has some incredible imagination cos its easier to believe the universe was created, than reason d alternative.Why is the latter easier to believe? Does ease of belief make a position right? If life evolved on earth, the same would have happened on Mercury or Pluto. Like i always say, aliens do not necessarily have to be anthropoid, they might as well breath nitrogen or thrive in extreme heat/fire; in fact d same way our kind of lifeform cannot thrive on Mercury because of d heat, a being on Mercury would find our environment hostile.Not quite. That's like arguing that because the earth has water, every other planet must have the same. It's a wrong assumption to think that conditions that have encouraged the evolution and perhaps even the generation of life on earth need indicate anything about beliefs about the earth and the other planets in our solar system. Do not underestimate the conditions on mercury, for instance. However, there's a good chance that life has sprung up and probably evolved on other bodies in the universe The Airplane, Cellphone and Computer didnt evolve, they were created; much less more complex beings like Man and Beasts.That's not an argument against the different lines of evidence that point to evolution. |
Maybe Creationists should just try the approach of conducting falsifiable research? No? The Institute For Creation Research Gets Slammed, Rejected By Federal Judge: http://blogs.houstonpress.com/hairballs/2010/06/creationism_higher_ed.php An excerpt: "It appears that although the court has twice required [ICR] to re-plead and set forth a short and plain statement of the relief requested, plaintiff is entirely unable to file a complaint which is not overly verbose, disjointed, incoherent, maundering and full of irrelevant information," Judge Sam Sparks wrote." |
mantraa:To be fair, when I think of and use the term "human" I'm referring solely to Homo Sapiens not all hominids. |
TV01:Yup For humans, given our population and genome? I'd say isolation of a small population and a lot of natural or artificial selection of thousands of mutations.However, yes, they are still humans, but one wouldn't expect just a known mutation here and there to cause speciation.So what would? Simply stated, Kangaroo rats are not actually rats. We have just presumed to label them that and assumed "evolution" from rats, as it can't be evidenced?Kangaroo rats are, nevertheless, rodents. Would a phenomena such as lions and tigers or horses and donkeys being able to mate, but producing sterile offspring be more suggestive? And are there different species of human, as this is not the case with us?I'm not sure I understand what you're asking when you enquire about lions and tigers, and horses and donkeys. More suggestive of what? There are no different species of humans - at least, not that has been found. Surely there must be something to lend greater credence to the "fish to amphibian" postulation?Yes, there are several somethings. Lungfishes represent a living example of fish with amphibious traits. And alternatively from the fossil record a transitional, Tiktaalik Roseae. |
TV01:And we do. From the community with Apo-AIM (http://www.talkorigins.org/faqs/information/apolipoprotein.html) to the community with a mutated limbs that gives them an advantage when it come to climbing (I'll have to find a link later), there are pockets of humans with some known beneficial mutations. The flip-side, of course, is the number of humans with maladaptive or damaging mutations. However, yes, they are still humans, but one wouldn't expect just a known mutation here and there to cause speciation. As for most mutations not being "physiological", thats nice to know, but presumably some do become codified over time?Yes I have no quibbles with any of this. But does this mean different/new creatures? This is merely variation in what I'd call the "genetic bandwith" inherent within each creature. Take dogs as an example. There're a million different "Mutt" variations, but they are all still dogs. And can viably mate with one another - Sausage Dog and Great Dane. Chihuhaha and Alsatian.It depends on what you mean by different new. Humans are still apes, as are bonobos. The difference between apes and dogs is that dogs are a ring species. A new species that cannot mate or produce fertile offspring with non Kangaroo rats? Again not to drag, species is a form of construct, I'm talking one creature "evolving" into a completely different one here.It's more than a case of them being bipedal. The kangaroo rat species can't mate nor produce a fertile offspring with other rodents. More than that, their features from their kidneys, lack of sweat glands and gestation periods set them apart. I don't know what you mean by something different emerging, but I suspect you're thinking of some sort of saltation which isn't what the theory of evolution states. |
Deep Sight:Yes there are variations within the various species of kangaroo rat, but it is the same process that led to the speciation within kangaroo rats that occurs in the evolution that eventually makes a fish amphibious, etc. |
TV01:Not really, no. I don't see the logic between a continuum and star trek and webbed feet, but, while there are humans with "Spock ears" and webbed feet, generally, the mutations that occur in most species are easily contained, repaired and/or unnoticeable amidst the many other proteins, etc in the genome. To be fair, many (most?) mutations, particularly in humans, are not physiological. Do biological threats - or any other kind - really lead to new species? Again, simply put, would a real biological threat take a "time out" for an "evolutionary response (over millenia)" to happen? There is either pretty much instantaneous change to cope or the population/sub-populace perishes. Just like when new diseases are introduced to populations. Resistance/immunity may be developed/acquired, but it will be based on the immediate ability to adapt no? Has it been shown to lead to an entirely new species?First, evolutionary adaptations don't "need" a millennia to occur: they may take place, depending on gestation, in generations. Second, genetic drift can also play a part, in that several small populations may have already possessed traits that help them to survive changes to their environment. Natural selection may then com into play. Finally, yes, the immediate ability to adapt - plasticity - varies between species, and many species will go - an have gone - extinct as result of less plasticity. Has it been shown to lead to new species? Yes. Rats make a good example as new species of rats have arisen based on changes, and/or transportation to new, environments. Kangaroo rats are a good example. |
I'll respond to this, then, as if it were addressed to me justcool:It's an interesting distinction, one I haven't had a reason to use, but it's one I can accept as anything else would just be semantics. So let's use phenotypic and evolutionary adaptations. The latter to describe identifiable genetic modifications that aid fitness in a population, and the former for temporal effects. However, you must accept that your current argument is a departure from the one to which I initially responded where "Evolution deals with change of a species from one species to another, over a very long period of time", amongst other things. In any case, can we also agree that a series of evolutionary adaptations can lead to speciation, and not necessarily over centuries but also in one to a few generations? justcool:I know it's often frowned upon by many, but I like the Wiki definition: "Acclimatization or acclimation is the process of an individual organism's phenotype adjusting to change in its environment, allowing it to survive changes in temperature, water and food availability, other stresses and often relates to seasonal weather change" Rather than simply dismissing it as not adaptation, I will instead classify it as phenotypic adaptation. |
justcool:It's more than a single step: adaptation is more akin to a series of steps, at which point it becomes difficult to draw a line between the steps taken and the journey that involves walking. While I have taken steps to leave room for adaptations that may not involve genetic change, I can't think of any that isn't genetic. I suspect there are some out there, but your example below isn't adaptation. That it's (most often) an effect of changes in the genes of a population is why I have said it's inseparable from evolution. An example of such adaptation is "Acclimation" which only involves acquired traits and not the genes. Such adaptation can be temporal, yet it is still adaptation because it is a response to a change in the environment, in such cases when the environment returns to normal, the organism loses the acquired traits.Acclimation is not an example of adaptation. A white person tanning is not adaptation. The reaction that causes tanning, not just in White people I might add, was a result of adaptation; wherein melanin is produced to protect the skin against UV rays. However, this is markedly different from your example, which involves mistaking the effect of an adaptation with the adaptation itself. The type of adaptation that leads to evolution comes from transmited genetic variations which is preserved by natural selection.Is there any other? An amphibian, for example would not return back to being a fish just because it returned back to the water. This is because evolution has taken place; but a whiteman will quickly lose his tan on returning back to Europe, this is because no evolution has taken place.While you're right in stating that a single organism can't evolve, a population can involve in a generation. Remember my analogy in my earlier post where I compared the relationship between adaptation and evolution to the relationship between a minute and a century.Yes. And like I said previously it's a wrong analogy. |
justcool:If your case was that adaptation is a part of evolution - inseparable and often sharing the same processes as speciation - then yes, I suppose your case has been made. |
justcool:If I were to be asked that in a science exam, my answer would be: There is a tangible difference only if the adaptation experienced by or within the species does not involve a change in the allele frequency of the population in question. |
JeSoul:Yes, I am indeed saying that a theory can never be proven to be fact. And this ties in to the answer to your second question. By science doesn't do proof, I mean that science, especially in its modern synthesis, avoids the urge to declare a series of findings concluded and proved. Proof implies closure and dogma: an ideal closed to further examination and unchangeable. That idea stands in stark contrast to the goal of modern science, where the teaching follows the thought espoused by Buddha: "question everything". The idea of leaving findings and explanations open to falsification becomes paradoxical if something is declared proven. I share the opinion that making predictions or projections based on current evidence is infact good science. I think the problem Justcool has (and I share) is that often these predictions can have a knack of keeping one in a theoretical box, a box with dimensions that have been predicted or guessed, and hence may not be accurate, and hence may limit our scope of research.That's a good point and I'm sure it does happen. However, biases can be minimised by having peer-review and independent lines of evidence. |
Deep Sight:Woah, woah, calm down, I wasn't going to use it as a refutation because I understood exactly what you were arguing both in this thread and the previous one. Stop jumping to hasty conclusions. |
justcool:No. First, adaptation is part of evolution. It is the same processes at work. In fact, you'd be hard-pressed several times to draw the line between a series of adaptation and speciation. Second, evolution needn't take a very long period of time to occur. No human, however, can mate(reproduce) with primates because they are of different species.While humans and other primates are different species, I'm not sure any tests to see whether humans can successfully mate with them have been carried out. There have been suggestions that a viable offspring can be produced from the mating of a human and some other ape. Something tells me we won't be finding out definitely, though. |
If you believe that dinosaurs had feathers that means you believe pigs have wings to fly.
i'm gonna try my best to address the issue at hand and not the personalities involved, also, everyone is entitled to their own opinions but a little common sense ought to prevail beyond the crazed search for facts where the obvious glares us in the face.
It doesnt make sense that these creationist guys r trying 2 "PROVE" creation. Faith is something u accept w/o question, not prove it.
), they are still humans and not another species or creature entirely.
