A new study sheds light on why humans are so much more intelligent than chimpanzees despite sharing almost 99% of the same DNA. Though humans have much the same genes as chimps, it seems that this genetic information can behave differently in the two species. When researchers looked how genes operate in human and chimp livers, brains and blood, they found the biggest differences in the brains. The work could help understand how humans evolved and why some diseases affected the two species differently Devamını Oku »
