The evolution of mating systems in animals has received an enormous amount of attention from biologists. This section briefly reviews three main findings about the evolution of monogamy in animals.
The amount of social monogamy in animals varies across taxa, with over 90% of birds engaging in social monogamy while only 3% of mammals are known to do the same .

There is no one-size-fits-all explanation of why different species evolved monogamous mating systems.
