Researchers have long assumed that these dramatic transitions resulted in a sort of accelerated evolution in which genes for traits such as skin color and stature changed rapidly to allow humans to survive in their new habitats.

Among the areas where the researchers have seen intriguing dissimilarities between humans and gorillas are in genes associated with sensory perception, keratin (a skin protein) production, insulin regulation, immunity, reproduction and cell signaling.
