During the evolution of primates their brain size, and specifically the size of their cerebral cortex where the higher cognitive functions are located, expanded. Stem cells in the human brain go through a higher number of cell divisions and thus produce a higher number of neurons then do stem cells in the brains of apes. The research presented in this video investigates which evolutionary changes in the genome caused this increase in cell division. WIELAND HUTTNER describes how the research group isolated the relevant human-specific stem cells and, using a new method devised by the group, studied which genes were particularly highly expressed in those cells.

Your explanation makes it easy for a layperson to understand the bases of higher cognitive function
Wow! This was mind blowing. Thank you!
Thanks for your experiment and explanation
bruh this dude is literally creating "planet of the apes"...
where in the sequence did the deletion of 55 nucleotides happen after point mutation at what position?
and can we use the position of deletion of nucleotides as a biomarker to find treatment for genetic mental disorders
They should have had "Shock The Monkey", Peter Gabriel song, playing in the background....... Great video.....
Anyone knows what's the status of their research now. Everything he said validated or discarded. This gene ARHGA...still considered to be the catalyst for brain enlargement?
how a single mutation changed humans forever
I was just waiting for him to say "And here we have Jan, the first talking mouse! What do you think abour our research, Jan?"
The Stoned Ape Theory
Bingo
fascinating to the point of tears!
Why did only about half of the mouse embryos brains start to fold, and not all of them?
Magic was the main ingredient , no gods involved since they wanted no ConNIVING human evolving 😎
I myself can't wait for the genius ferrets to arrive..
That mice should be Phd now
Very well detailed
The research work of American Biologists Paul McClean in the 50's on the R complex & its early stages of development in the brain, sourced by Carl Sagan in 'Cosmos' is also extremely educational
the human brain records and archives everything we experience, creating partitions that hold memory archives, as the experiences demand, and this phenomenom will be passed on to each generation, through their genome! my opinion!
Apa apa apa Miss
Um no. That is completely wrong. Opinions cant be facts
a high saturated fat diet is key to brain evolution and size
'I'm not fat, I'm big -boned- brained'
title should be: how we engineered smarter mice! with human dna
can we add stem cells or something else way, more brain cells? 600 IQ could be handy for big questions
if we know the exact position of mutuation we can possibly cure certain mental disorders by causing this mutuation through some drugs that enhances this mutation
Wow, so does mice actually got smarter?
I’m very interested in the natural process of the way humans interact with each other and the natural processes of the environment and how humans should reinterpreted natural ways of looking after the environment instead of leading agricultural with western farming practices that don’t work for every environment and work with nature because when have we won against nature never
Get some orangutans, express this gene, and microdose psilocybin. I imagine there would be interesting developments.
Hook a nueralink to the tripping GMO orangutan and already we have a more competent candidate for the presidency than Donald Trump
@@johnbush5325 here we go, too bad u are not on twitter to get likes to make u feel good. keep ur politics out of science jesus christ.
@@XxvoleistulxX Politics cannot stay out of science until politicians are no longer anti-science. Like Donald Trump, who denies climate science and virus science doesn't value science funding and beliefs in creationism.
@@johnbush5325 this is a video about the brain, thats why americans are so hated. You and trump can go fk urselfs.

You mean it might be possible to fix stupid?
i have a lot of neanderthal genes in me (note that was from my intuition, so i could be wrong) i'm an asperger's syndrome from australia
note i haven't even got up to 7:27-7:43 when i posed that comment i just now got to it
Cut the carbs and your asperger's will go away.
