Primates are relative newcomers on our planet. The earliest ones are found in the fossil record dating to 50-55 million years ago. These first prosimians thrived during the Eocene Epoch. There were no monkeys or apes for them to compete with yet.he first true primates evolved by 55 million years ago or a bit earlier, near the beginning of the Eocene Epoch. Their fossils have been found in North America, Europe, and Asia. They looked different from the primates today.
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. 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.
