Question

mammalls.have.here.on.their.body​

Answer 1

Answer:

Yes, mammals have hairs on their body

Answer 2

This means that even whales, elephants and dolphins have body hair! ... But a good guess would be that we evolved hair (or fur) to conserve body heat. Mammals are warm-blooded, which means that we require a high internal body temperature to survive. Very few animals other than mammals are warm-blooded.
