What should you do to test the hypothesis that hair length has been influenced by evolutionary selection?

Cotton-topped tamarins are small primates with tufts of long white hair on their heads. While studying these creatures, you notice that males with longer hair get more opportunities to mate and father more offspring.

A. Look at the characteristics of male hair in ancestors of tamarins

B. Test whether males with shaved heads are still able to mate

C. Test whether other traits in these males are adaptive

D. Determine if hair length is heritable

Answer: Option D

Explanation:

The hypothesis is to test whether hair length is heritable or not. The cotton topped tamarins are primates in which some of the individuals have long hair and some of them have short hair.

They have tufts of long white hair on their head and the males that have longer hair get more chances to mate.

In this process, the hypothesis was based on the fact that whether the length of hair is a heritable trait or not.
