Mouse embryo with really big brain: Evolving a bigger brain with human DNA

19 febrero 2015

The human brain expanded dramatically in size during evolution, imparting us with unique capabilities. Scientists have now shown that it’s possible to pick out key changes in the genetic code between chimpanzees and humans and visualize their respective contributions to early brain development in mouse embryos. The findings may lend insight what makes the human brain special and why people get some neurological disorders, such as autism and Alzheimer’s disease, whereas chimpanzees don’t.
