> A rather astounding statement. Selective pressure should result a ratio appropriate for a given species of plant or animal. It’s not my field, but I haven’t seen any literature suggesting any such thing, nor do I know of any country full of sultans.
This is not actually true. The math works out that there is usually an even ratio between males and females, and that this is even the case in tournament species (where one male is able to mate with multiple females.) The thing to understand is that in this hypothetical, it wouldn't be a country full of sultans, but a country full of would-be sultans. A very different proposition.
