Today, all humans are classified as belonging to the species Homo sapiens and sub-species Homo sapiens sapiens. However, this is not the first species of homininae: the first species of genus Homo, Homo habilis, are theorized to have evolved in East Africa at least 2 million years ago, and members of this species populated different parts of Africa in a relatively short time. Homo erectus is theorized to have evolved more than 1.8 million years ago, and by 1.5 million years ago had spread throughout Europe and Asia. Virtually all physical anthropologists agree that Archaic Homo sapiens (A group including the possible species H. heidelbergensis, H. rhodesiensis and H. neanderthalensis) evolved out of African Homo erectus ((sensu lato) or Homo ergaster).
What group might have Archaic Homo sapiens evolve out of?
African Homo erectus

Shortly after the end of the war in May 1945, Germans who had fled in early 1945 tried to return to their homes in East Prussia. An estimated number of 800,000 Germans were living in East Prussia during the summer of 1945. Many more were prevented from returning,[citation needed] and the German population of East Prussia was almost completely expelled by the communist regimes. During the war and for some time thereafter 45 camps were established for about 200,000-250,000 forced labourers, the vast majority of whom were deported to the Soviet Union, including the Gulag camp system. The largest camp with about 48,000 inmates was established at Deutsch Eylau (Iława). Orphaned children who were left behind in the zone occupied by the Soviet Union were referred to as Wolf children.
How many forced labourers were in the largest camp?
48,000
