In the development of Homo sapiens our ancestors had varying degress of abilities. The "Stone Age" was thought to be a fairly recent event. It takes some skill to hammer stone at the right cleavage points to create sharp edges. Such stone edges have been found, dated 500,000 years ago, predating Neanderthals and us. http://sciencenow.sciencemag.org/cgi/content/full/2009/402/2
