The Evolution of Man

[Spalea]

@parvez:

You quote: "Yes they are efficient runners but in terms of intelligence and brain size they are very poor. Their brain size is particularly pathetic. Even if we consider the case of birds their forearms are modified into wings but that did not make them as intelligent though they can fly which rarely other animals can do. Evolution of man is truely mesmerizing topic. There is lot to study.

The ostrichs only had an anatomical advantage, they stayed with their very pathetic brain size, I'm quite agree. As concerns the man the bipedial posture gain leaded them obviously into a quite different situation: the specificity of the mankind. Reply
