Question

Develop a time line for hominid evolution giving the order of appearance of Homo erectus, Australopithecus, Homo sapiens sapiens, Homo habilis and Homo sapiens neanderthalensis.

Answer 1

Chronological order, from earliest to latest: Australopithecus (about 5 million years ago) → Homo habilis (about 2 million years ago) → Homo erectus (earliest fossils about 1.7 million years old; Java and Peking fossils about 500,000 years old) → Homo sapiens neanderthalensis (about 70,000–40,000 years ago) → modern Homo sapiens sapiens (expansion about 10,000 years ago, according to the text).
