Question

Quizplus · Accepted Answer

The first hominins are believed to have evolved about 4 million years ago during the Pliocene epoch. This is based on fossil evidence of early hominins such as Australopithecus afarensis, which was discovered in Ethiopia and is believed to have lived around 3 to 4 million years ago. Earlier periods such as 200 million, 100 million, and 50 million years ago predate the evolution of primates, let alone hominins, while 1 million years ago is much later in the evolution of hominins.
