Chicks always go for the alpha, we're animals after all. I mean I think the term beautiful ones probably just referred to them being unharmed by what would be behaviour they normally engage in, as a result of them having all basic needs catered for they become docile and asexual. The equal opposite is where no needs are met and the mice are offered cocaine, and the rat would take the cocaine until it overdoses and dies.

It could be that the city life leads to homosexuality and sexual deviancy due to these reasons, or it could be other contributing factors. We see many mental health issues rise in cities compared to smaller towns, we just aren't evolved to be around noise, lights and high density populations 24/7. Or it could just be more prevailing due to the fact that there are more people in a small space to account for a greater statistic.

It's worth noting though that when badgers are culled in the UK to reduce tuberculosis, badger populations dramatically bounce back soon after. In high population animal groups, mating will stabilise or reduce, this perhaps why Europeans are not breeding as much these days, they are densely populated.
