The movement of the continents over the past 135 million years. In the early Cretaceous (circa 135 million years ago), there were two “supercontinents”: Laurasia, which included North America and Eurasia; and Gondwanaland, which included Africa, South America, India, Australia, and Antarctica. By the beginning of the Paleocene (circa 65 million years ago), Gondwanaland had broken apart, with South America drifting west away from Africa, India drifting east, and Australia and Antarctica drifting south.

The geological epoch 65 million to 55 million years ago.

The geological epoch 34 million to 24 million years ago during which definite anthropoids emerged

The geological epoch from 24 million to 5.2 million years ago.

The geological epoch 5.2 million to 1.6 million years ago during which the earliest definite hominins appeared.

A geological epoch that started 1.6 million years ago and, according to some, continues into the present. During this period, glaciers have often covered much of the earth’s surface and humans became the dominant life form
