WHY do goats wear beards?

Circumstantial evidence of this is the characteristic habit of goats to rub their beards with the secret of their under-tail glands (which are absent in females), which contain sex pheromones.

As zoologists assume, it is a "physiological calendar" that allows congeners to determine the age, condition and also to become an individual.

This feature plays an important role for contacts between members of the same species.
