Monogamy seems completely impractical from an evolutionary perspective. If the "goal" of the survival of the fittest is to pass on your genes, how can limiting yourself to just ONE mate make any sense at all? Wouldn't playing the field be the best way to succeed? In most cases, yep. But in some select species, monogamy is the best strategy. Today we are going to talk about why monogamy evolves, and the biological benefits of monogamy under specific circumstances. Happy Valentine's Day!
