Can you identify the key changes that occurred during hominid evolution?

2.7 mya Neanderthal lives in woods and grasslands, has massive jaws for chewing on roots and vegetation.

2.5 mya Hominids start to use stone tools regularly, develop a brain 850 cm'.

Between 4-6 mya ape-hominin transitional species adopted bipedalism.

1.8 mya Homo erectus is found in Asia. First true hunter-gatherer ancestor, first to migrate out of Africa in

large numbers and attains a brain size of around 1000 cm

Australopithecus had a combination of humanlike and apelike traits: they were bipedal but had small

brains.

Homo habilis appears to be intermediate in terms of evolutionary development between the primitive

Australopithecus and the more advanced Homo species.

1.5 mya Homo Heidelbergensis lives in Africa and Europe. Similar brain capacity to modern humans.
