Comparative genomics and the evolution of language
|

New York, USA (New York Times): If language evolved like any other biological trait, where is the trail of natural selection? Until recently, there was little direct evidence of language's evolution. Languages don't leave fossils, and while there has never been any dearth of theories explaining why language might have evolved (be it for grooming, gossip or seduction), empirical evidence has been hard to come by. All that is finally starting to change. The booming science of comparative genomics is allowing researchers to investigate the origins of language in an entirely new way: by asking how the genes that underwrite human language relate to genes found in other species. And these new data provide a fresh example of the power of natural selection.
