With this easy check out the male delivers just the sperm plus a widening in the gene pool. Even so it would usually be way too highly-priced in means (in evolutionary conditions) for that to get the only real purpose of males, and so social responsibilities have evolved. Males typically seem immediately after their mate and offspring by assisting to present foodstuff, defense along with a ‘dwelling’.
