The FOXP2 gene, the only gene known to be language-related, is usually said to be between 100 and 200 thousand years old; however, that date is based on a technically flawed analysis and the correct date for the gene's origin may be 1.8 to 1.9 million years ago, according to a report presented today (Nov. 7) in Stellenbosch, South Africa by two representatives from the University of Hawaii's School of Medicine, Karl Diller and Rebecca Cann. (Abstract here.)
This blog is in no position to consider the technical argument made, but if the date stands up it will push the discussion back to the beginnings of Homo rather than at its end, where many people put it today.
