The Acheulean hand axes begin to appear at around :

  • A.4.6 Ma
  • B.1.76 Ma
  • C.0.78 Ma
  • D.50,000 years BP

Answer: B

Acheulean hand axes first appear at about 1.76 Ma.

The oldest securely dated Acheulean tools, from Kokiselei in West Turkana, Kenya, are about 1.76 million years old, and are associated with Homo erectus. The Acheulean then lasted until roughly 200,000 years ago.

4.6 Ma is older than any known stone tool (the Oldowan begins about 2.6 Ma). 0.78 Ma is the Brunhes-Matuyama reversal, long after the Acheulean began, and 50,000 years BP falls in the Middle to Upper Palaeolithic.
