The following is an excerpt.
Chimpanzees are the closest living relatives to humans, and researchers continue to hunt for clues when it comes to understanding how our evolutionary paths diverged. Now, scientists may have the answer. They’ve found further proof that the divergence of humans and chimps that occurred between four to six million years ago was profoundly influenced by mutations to DNA sequences that play roles in turning genes on and off.
