<<Contrary to what they are suggesting, the biological evidence of language is
first found in the fossil record from 2 million years ago in the brain of
Homo Habilis.>>
But this view seems at odds with the following:
"This capacity for language seems to be, in the evolutionary scale, a
relatively recent, sudden, and explosive development. A few years ago, it was
thought to have begun to happen with Homo erectus perhaps a million years ago.
Now, as Julian Jaynes at Princeton, among others, believes, it appears to have
occurred in Neanderthal man as recently as the fourth glaciation, which lasted
from about 75,000 to 35,000 years ago." [Percy, "Is a Theory of Man
Possible?"]
