Question
Homo erectus and Homo sapiens are two widely recognized hominid species. In contrast, the hominids that are younger than most Homo erectus fossils but older than the majority of Homo sapiens fossils have been loosely categorized as "archaic" Homo sapiens. Why have these fossils not been given a distinct species name, and why do they remain so difficult to classify formally?Answer
