Chinese Scientists Defend Implanting Human Gene Into Monkeys' Brains by icnsystem(m): 11:23am On Apr 12, 2019
A Chinese researcher who sparked improved cognitive function in monkeys by implanting human genes into their brains has defended his experiment, which has divided the scientific community.
The research, undertaken by multiple universities and led by the Kunming Institute of Zoology in southwestern China, was intended to shed more light on the evolutionary process which led to human intelligence.
"Brain size and cognitive skills are the most dramatically changed traits in humans during evolution, and yet the genetic mechanisms underlying these human-specific changes remain elusive," said a report published on March 27 in the China-based journal National Science Review.
The research paper said it was the first time such a study had taken place.
One of the lead researchers Su Bing, from the Chinese Academy of Sciences' Kunming Institute of Zoology, said the experiment has been reviewed by the university's ethics board and had followed not only Chinese and international best scientific practices, but also international animal rights standards.
"In the long run, such basic research will also provide valuable information for the analysis of the etiology and treatment of human brain diseases (such as autism) caused by abnormal brain development," he said in an email to CNN.
But scientists who have long debated the ethics of transgenic experiments on monkeys and apes have said the experiment leads researchers down a "risky road."
It is the second gene-related controversy to hit researchers in China in less than six months. In November a Chinese scientist claimed he had created the world's first gene-edited babies, sparking an international outcry.
He claimed to have used a tool known as CRISPR-cas9 to remove the genes that made the children susceptible to HIV. Chinese authorities took a dim view of the experiment, branding it "illegal" and ordering an investigation.
In Su's 2019 study, 11 rhesus monkeys were successfully implanted with copies of the human MCPH1 gene, an important marker for "brain development and brain evolution."
Analysis of the monkeys' behavior and physiology showed they developed in a more human-like fashion, with better short-term memory and a faster reaction time compared to a control group.

Their brains also took longer to develop, in a similar fashion to humans.
The research has been criticized by a number of Western scientists. University of Colorado geneticist James Sikela said it was a "very risky road to take."
Sikela and his colleagues had argued in a paper published in 2010 that transgenic experiments on non-human primates raised complicated ethical issues and that enhanced primates would be at greater risk of exploitation and harm.
"These harms render the conduct of this research ethically unacceptable in apes, justifying regulatory barriers between these species and all other non-human primates for transgenic research," the 2010 paper said. The paper did, however, concede the research could be valid in some situations.
In the MIT Technology Review, University of Colorado bioethicist Jacqueline Glover compared the experiment to the sci-fi dystopian movie "Planet of the Apes," in which super-intelligent primates overthrow humans.
"To humanize them is to cause harm. Where would they live and what would they do? Do not create a being that can't have a meaningful life in any context," Glover said.
But Chinese scientist Su accused Western critics, and Sikela in particular, of hypocrisy and recklessness, saying that the project was being unfairly judged by Chinese research "stereotypes."
"Exploring the genetic mechanism of human brain evolution is a major issue in the natural sciences, and we will continue our exploration," he said.

CRISPR-CAS9 is a revolutionary Gene editing technology. I will definitely take a hold of that Technology in the next few years and design me some entities. It is time Man, takes his rightful place as God and navigate to a new plane of existence with the best Genetic Engineers and design great species that will worship us as Gods, not knowing we are mere mortals like them.

But I will ensure that their lifespan is less 20 years so they wont have long enough life span to figure out I am just Man, but I guess many will think I am actually God and worship me like the religious people worshipping the Homo Capenses Elohims and Annunakis not knowing they are also Mankind from a different plane of existence.

Religious people's ignorance will soon be very exposed.

First redesign yourself as a test. we are watching.
