Recorded history explains that the penis was found to have its first origin in the reptilian age some 200 million years ago. I find it interesting that the snake replicated the phallus from history’s study of genetic memory yet, is the bad guy in the Christian myth of Eve and Adam in the Bible’s interpretation of creation, I just find this an interesting point.
In the studies of marine biology, there is a particular crustacean that reproduces many generation of females by parthenogenesis. The egg and its own polar body mate together forming a complete set of female genes for the reproduction of yet another female offspring. Only once a year there is born a male group which has a very short life simply to produce a strong protective egg encasements in order to survive the winter months.
Just something to think about.
