New Recreation: Singing Mice by ekensi01: 7:20pm On Jul 16, 2017 |
•SINGING MICE•
A team of researchers at
the University of Osaka
are breeding genetically
modified mice that are
prone to miscopying
DNA and are more likely
to develop mutations.
The 'tweeting' mouse
was created as part of
the team's ‘Evolved
Mouse Project. They
hope it will shed new
light on how languages
evolve.
"We checked the newly
born mice one by one...
One day we found a
mouse that was singing
like a bird,’ he told AFP.
He said that the ‘singing
mouse’ was born by
chance but that the trait
will be passed on to
future generations.
The project has also
produced ‘a mouse with
short limbs and a tail
like a dachshund’.
The laboratory, directed
by professor Takeshi
Yagi at the Osaka
University’s Graduate
School of Frontier
Biosciences in western
Japan, now has more
than 100 ‘singing mice’
for further research.
The team hopes they
will provide clues on
how human language
evolved, just as
researchers in other
countries study
songbirds such as
finches to help them
understand the origins
of human language.
'Mice are better than
birds to study because
they are mammals and
much closer to humans
in their brain structures
and other biological
aspects,’ Uchimura said.
‘We are watching how a
mouse that emits new
sounds would affect
ordinary mice in the
same
group... in other words
if it has social
connotations,’ he said,
adding that ordinary
mice squeak mainly
under stress.
Uchimura said their
chirps ‘may be some
sort
of expressions of their
emotions or bodily
conditions.’
The team has found
that ordinary mice that
grew up with singing
mice emitted fewer
ultrasound squeaks
than others.This could
mean that
communication
methods can spread in
the same group like a
dialect.
