Chimpspeak

Randy Crawford sent this question in today:

“Chimps can talk like humans only with difficulty, owing to their lack of human vocal cords. Has anybody tried letting them use an electrolarynx or voice synthesizer such as humans are lent after throat surgery? If such equipment is good enough for Homo sapiens, chimpanzees could only be more worthy. Random examples off the internet:
http://en.wikipedia.org/wiki/Electrolarynx classic type.”

The problem isn’t muscular control, but the absence of mental acquisition device in the brain. Chimps can perform as well as children up to the age of two—some even better. But that is when the “explosion” of language acquisition occurs in children. It doesn’t occur in any subspecies of chimpanzees, not even Bonobos.

We can only conclude that Noam Chomsky is right and that humans are qualitatively (not just quantitatively) different from chimpanzees, and that humans are qualitatively different from all other species. That 1.8% difference in DNA may seem quantitatively small, but it makes a big qualitative difference.
