Homo erectus (meaning upright man, from the Latin Ärigere, to put up, set upright) is an extinct species of hominid that lived throughout most of the Pleistocene geological epoch. Its earliest fossil evidence dates to 1.9 million years ago and the most recent to 70,000 years ago.
By 1.9 million years ago, some of the early transitional humans had evolved into a new, fully human species in Africa. Most paleoanthropologists refer to them as Homo erectus (literally upright human). However, a few researchers split them into two species--Homo ergaster (literally working human) and Homo erectus.The ergaster fossils were presumably somewhat earlier and have been found for the most part in Africa.The erectus discoveries have been found widespread in Africa, Asia, and Europe. In this tutorial, ergaster and erectus will be considered one species--Homo erectus.he ergaster fossils were presumably somewhat earlier and have been found for the most part in Africa.
