Scientists from the United States, Belgium and France identified 49 "human accelerated regions" (HARs) showing a lot of genetic activity.In the most active, identified as HAR1, they found 18 out of the 118 nucleotides had changed since evolutionary separation from chimps some 6 million years ago, while only two had changed in the 310 million years separating the evolutionary lines of chimps and chickens.
"Right now we have very suggestive evidence that it might be involved at a critical step in brain development, but we still need to prove that it really makes a difference," team leader David Haussler from the Howard Hughes Medical Institute and the University of California, Santa Cruz told Reuters.
Do you see how measured and cautious scientists are when talking about such a world shaking discovery? That is the difference between zealotry and intellectualism.
How can you not love scientific discovery?
