What are the evolutionary purposes of men having beards and women not?
I'm interested in learning about why men have beards and women do not. What is the evolutionary purpose behind it?
That's a great question! One theory is that beards may have evolved in men as a way of signaling dominance, aggression, and sexual maturity to other males and to potential mates. Additionally, beards may provide some protection against physical harm or facial injuries.
