describe the change in climate and vegetation and impact upon australopithecus
Answers
Overall, the hominin fossil record and the environmental record show that hominins evolved during an environmentally variable time. Higher variability occurred as changes in seasonality produced large-scale environmental fluctuations over periods that often lasted tens of thousands of years.
afarensis possessed both ape-like and human-like characteristics. The top of its skull (the cranial vault) was slightly domed and its brain was comparable in size to a chimpanzee's. Its face projected outwards, less so in females than in males.
They also had small canine teeth like all other early humans, and a body that stood on two legs and regularly walked upright. Their adaptations for living both in the trees and on the ground helped them survive for almost a million years as climate and environments changed.
