What are the differences and similarities between skeletons of human beings and chempanze?

Answer 1

The volume of the human brain case averages 1400 cm3, while the chimpanzee brain case averages 400 cm3. • Human canines are small in both sexes; chimpanzee canines are larger in males. • Chimpanzee metacarpals are longer and more curved for climbing in trees and knuckle-walking on the ground. • The human thumb is relatively longer and has well-developed musculature for fine manipulation. • The chimpanzee clavicle angles upward; the human shoulder joint is lower. • The thorax of the chimpanzee is broad compared to the human thorax. • The human spine is curved for balance during bipedal locomotion. • The human pelvis has a short, broad ilium and a short ischium. This is also an adaptation for bipedality. • The human femur is distally angled inwards towards the midline. This is called a valgus knee and helps with balance during walking. • Human toes are shorter than chimpanzee toes. • The big toe of the human is adducted, or drawn in line with the rest of the toes, compared to the
