Dr Kevin Kuykendall appears on CBBC's Newsround

As part of their coverage of the discovery of the earliest known fossil of the Homo genus, CBBC's Newsround asked Kevin Kuykendall of the University of Sheffield Archaeology Department to comment on the remarkable discovery of a jawbone proving that humans were alive much earlier than had previously been thought.

Kevin can be seen discussing the fossilised jawbone recently found in Ethiopia and why it is so significant on the CBBC Newsround website.
