Monogamy may have a telltale signature of gene activity
In the animal world, monogamy has some clear perks. Living in pairs can give animals some stability and certainty in the constant struggle to reproduce and protect their young—which may be why it has evolved independently in various species. Now, an analysis of gene activity within the brains of frogs, rodents, fish, and birds suggests there may be a pattern common to monogamous creatures. Despite very different brain structures and evolutionary histories, these animals all seem to have developed monogamy by turning on and off some of the same sets of genes.
"It is quite surprising," says Harvard University evolutionary biologist Hopi Hoekstra, who was not involved in the new work. "It suggests that there's a sort of genomic strategy to becoming monogamous that evolution has repeatedly tapped into."

When someone mentions polygamy I tend to think of places like Colorado City [wikipedia.org] which sounds like an absolute hellhole if you're not one of the chosen few.
Or a woman.
