It makes sense that men and women have different reproductive giblets. It makes sense about different bone density and muscles. But why do men have Adam’s apples?
In: Biology
Adam’s apples are a secondary sex characteristic. Secondary sex characteristics are traits that aren’t essential for reproduction but increase the chances of an individual to reproduce. The Adam’s apple gives man a deeper voice than they normally would have.
The pitch of our voice is usually roughly correlated to our body size as the size of the larynx and the vocal chords is proportional to the rest of the body. For this reason a person with a deeper voice is perceived as bigger and stronger. At some point in human evolution this could have been an advantage for males with deeper voices while looking for mating partners. Those individuals had more children and spread the genes for deeper male voices. Leading to men with bigger and bigger larynxes. In modern human males the larynx is close to the size where it would start to create problems with eating.
Because the deepening of the voice is linked to the male puberty it is also an indicator for maturity and health.
