Penis size debate

[egoldstein]

Personally, I'd like a smaller penis, but I would agree that there's some selection pressure for a large penis.




Dawkins discusses possilbe selection pressures on human penis size, as well as the evolved lack of an os penis in humans, in "The Selfish Gene" (second edition preferred, as it contains more discussion on the topic)




In a discussion about how the lack of an os penis (baculum/pizzle) could lead to the penis becoming a diagnostic of health in a male he states,  "It is not implausible that, with natural selection refining their diagnostic skills, females could glean all sorts of clues about a male's health from the bearing of his penis."
