I know we had several posts in the past, regarding how marriage makes men less aggressive.

Evolutionary biologists have long debated whether the behavior of the individual is able to influence processes on a population or species level. The possibility of selection at species level is still controversial. Using a mathematical model, an international team of researchers led by Daniel Rankin, an evolutionary biologist at the University of Zurich, has now demonstrated that aggressive male sexual behavior not only harms the female, but can also cause entire populations to die out.

It's a good read, and relates to our own behaviors in how we change the environment. The quality of marital men have decreased, either women deal with it or don't have any children at all, which seems to the case within our own species.
