Question

write a short note on primates

Answer 1

Primates are the mammals that belong to order primate. Primates are divided into two groups which contain prosimians (including lemurs, lorises, galagos and tarsiers) and anthropoids (monkeys and apes - including humans).

These are the certain characteristics of primates:

Unfused and highly mobile radius and ulna in the forelimb and tibia and fibula in the hind,

Comparatively poor sense of smell,

Prehensile five-digit hands and feet possessing flat nails instead of claws

Primate teeth are distinguishable from those of other mammals

 

The mammals which do not have these characteristics are called non- primates.

According to researches the primates are considered as divergent from other mammals. They started to diverge about 85 million years ago. Every one of our primates, from apes to chimps are diverged from other mammals between 15-20 million years ago. Our common divergent ancestors gave birth to human just around 2 million years ago.
