Question

List the four species of the Homo genus that evolved from Australopithecus afarensis in East Africa.

Answer 1

The Homo genus species to evolve from Australopithecus afarensis in East Africa include Homo habilis, Homo erectus, Homo heidelbergensis, and Homo sapiens.

Step-by-step explanation:

The four species of the Homo genus that evolved from Australopithecus afarensis in East Africa are:

1. Homo habilis - First known species in the genus Homo that lived from about 2.5 to 1.4 million years ago and may have been ancestral to Homo erectus.
2. Homo erectus - Early species in the genus Homo that first evolved about 1.9 million years ago, showing a significant increase in brain size and reduction in the size of the face and teeth compared to earlier hominins, and was probably ancestral to Homo heidelbergensis.
3. Homo heidelbergensis - A species thought to have evolved from Homo erectus, living around 600,000 to 200,000 years ago and may be a common ancestor to modern humans and Neanderthals.
4. Homo sapiens - Our own species, which emerged around 300,000 years ago.
