According to a recent study published in the journal Nature, scientists have discovered that a gene called FOXP2, which is believed to be responsible for the evolution of speech in humans, behaves differently in humans than it does in chimpanzees, our closest living relatives. The gene produces a protein in humans that differs by just two amino acids from chimpanzees’ FOXP2 protein. Think about it—if not for those two amino acids, chimpanzees might be able to talk. If they could speak, what would they say?
Actually, we already know what they would say, thanks to the work of people such as Roger Fouts, a professor at Central Washington University who is famous for teaching chimpanzees American Sign Language (ASL).

Washoe spontaneously combined words to describe her experiences and desires, using expressions such as “you me hide” and “listen dog.” She also invented names for her possessions, referring to her doll, for instance, as “Baby Mine.” She was even known to fib and tell jokes.
