Did Australopithecus live in the ice age?

No, Australopithecus did not live during the ice age. This genus of early hominins existed between approximately 4 million and 2 million years ago, well before the onset of the Pleistocene Ice Ages, which began around 2.6 million years ago. Australopithecus thrived in warmer, more diverse environments, such as woodlands and savannas.
