How does sperm fertilize the egg?

Answer 1

Well, it depends on the species. Often there is a mating season, during which males are frequently observed attempting to impress the females with their mating display. This might involve loud calls or songs, brightly colored fur or feathers or bodies, ritualized dance, gifts of food to display hunting prowess, or fighting with other males to show off their strength. It is unknown whether the females find all of this to be stimulating or ridiculous. In any case, the female chooses and mating commences, and in time offspring hatch/are born. This is not the only way in which adults of a species join for mating, but it is a pattern followed by many of Earth's creatures, including us.
