Answer 1

Answer:

(a) Dryopithecus

Dryopithecus lived 15 mya (million years ago) in Africa and Europe. They were ape-like, hairy and they walked like gorillas. They had semi-erect posture and large brain size. They were arboreal (lived on tress). Dryopithecus is considered as the direct ancestor of modern day apes.

b) (i)First man-like animal was found in Ethiopia and Tanzania.

(ii) The order of appearance from earliest to the latest is Homo habilis, Homo erectus and Neanderthals.

The brain capacity of Homo habilis is 650-800 cubic centimeters, Homo erectus is 900 cubic centimeters and Neanderthals is 1400 cubic centimeters.

(iii) Modern Homo sapiens appeared between 75,000- 10,000 years ago.
