Solution
The correct option is A Shortening of jaws
Advanced features developed in human during the evolution are as follows:
1. Perfect bipedal locomotion with straightening of knees, shortening of toes.
2. There is reduction in the size of jaws with smaller teeth.
3. Higher cranial capacity.
4. Loss of hair from many body parts.
Binocular vision is the feature of almost all primates. It has not evolved during human evolution. Apes such as chimpanzee, gibbons also have binocular vision.
Chimpanzees and man have flat nails.
Tail is not completely lost during human evolution. Humans have a tailbone which is present as a vestigial organ.
Hence the correct option is
d. Shortening of jaws
