Mammals have only been "dominant" for 65 Ma

Look at the heat-dependent sex of reptiles, the XX-dominance of birds, age-related sex in fishes, and some realy wierd stuff that happens in nematodes and other primitive life.

Nothing magic about XY males or 2-sexes or whatever.

If you were a male bee, you would get one chance in your life to have sex. If successful, you would be a father of a million offspring, but otherwise you would be a useless drone...
