Common alleles become more concentrated the gene frequency increases in other words and animals become more and more closely related with each generation. In species that mate via internal fertilization, its pretty obvious that multiple males cant mate with a female at the same time, and thus they must compete with each other. The statement above is a gross generalization, but biologically it tends to be true across most species that reproduce sexually, whether they reproduce with internal or external fertilization. When females continually move and are not spatially stable, males pursue a mate defense strategy. The offspring within a polygamy also struggle with the effects of polygamy; while they may enjoy the undivided attention of their mothers, the father cannot do justice to every child equally.
