 In August 2008, 9-year-old Matthew Berger, the son of Lee Rogers Berger, found a clavicle and a jawbone embedded in a rock near Malapa Cave in South Africa.Subsequent excavation, headed by Berger, led to the discovery of numerous bones nearby that dated back nearly two million years.Along with various co-authors, Berger published a series of articles between 2010 and 2013 in the journal "Science" that describe what they call a new species, "Australopithecus sediba", which had a mixture of primitive and modern characteristics.
