Early Modern Homo sapiens. All people today are classified as Homo sapiens. Our species of humans first began to evolve nearly 200,000 years ago in association with technologies not unlike those of the early Neandertals. It is now clear that early Homo sapiens, or modern humans, did not come after the Neandertals but were their contemporaries.
Today it is believed that the homo sapiens first appeared 1million years ago. They first showed up in the Cenozoic Era, the Quaternary period, and in the Peilstocene Epoch.omo sapiens is a species of primate that has 2 subspecies, Homo sapiens neanderthal (extinct) and Homo sapiens sapiens (us!).
