Linguists are calling for an online public database, similar to the human genome project, that would allow researchers to collaboratively share different studies of language impairment.
...The biological basis of how people speak, listen and comprehend - and how all of this mental equipment evolved - is largely mysterious. With many psychological abilities, researchers can study animals to gain insights, but this is not possible with language as no animal communication systems are anywhere near as complex as ours.
"In short, we know it's unique to humans and it evolved quickly," says Marcus. We developed the skill after we split from our last common ancestor - shared with chimpanzees - seven million years ago. Nevertheless, he says, language probably evolved as recently as the last few hundred thousand years.
