2.8 million years ago
Modern humans belong to a group or “genus” of animals known as Homo. The oldest known Homo fossil, found in Ethiopia, is 2.8 million years old. The first species was probably Homo habilis, although this has been disputed. Compared to their ancestors, these new hominins had much larger brains.
