    Heard an interesting piece on NPR's All Thing Considered yesterday
    (http://www.npr.org/blogs/health/2014/11/06/361794562/how-boy-bits-first-came-to-be)

    To summarize:
    (1) Penises weren't necessary in our ocean-dwelling ancestors
    (2) Snakes have two hemipenes : the limbs got hijacked to become the hemipenes and there are two hemipenes because there are two limbs
    (3) The penises of mice form near the tail, not around the legs, why?
    DRUMROLL
    (4) The anus, or asshole, give cells the order where to grow/form organs (including the penis, or cock). The digestive track is our most ancient parts. As more complex animals develop in the womb (as they evolve), it's the gut that spurs other organs to grow.

    The study is motivated by the increase in birth defects of genitals, and was published in Nature this Wednesday (http://www.nature.com/nature/journal/vaop/ncurrent/full/nature13819.html).

    Wish I could crosspost this in other fora ...

    QUOTE AUTHOR GOES HERE"In the past 30 to 40 years, the incidence of genital-urinary defects has risen, sharply," he says. "We don't really understand why."


    Duh! What was the purpose of this article then? To love our gut?

    The other great chicken-and-egg question: clit or cock?

    Particularly given that all men have a clitorus - a cock is, essentially, an inverted clit.
