Somewhere in my computer there is an article about the sexual behavior of male orangutans (the "man of the forest").

  • Wikipedia
My memory of that missing paper recalls it saying something about two types of male orangutans. One type sings to attract females. It sings and waits and hopes a female will be drawn to its song of love. The other type of orangutan rapes females. It sees a female and forces himself on her. If my memory is correct about this paper, there isn't a middle male, one that doesn't resort to art or crime to procreate.
