Category:Secondary sexual characteristics
From Infogalactic: the planetary knowledge core
Secondary sexual characteristics are traits that distinguish the two sexes of a species, but that are not directly part of the reproductive system. Some have argued that in general they evolved to give an individual an advantage over its rivals in courtship. They are opposed to the primary sexual characteristics: the sex organs.
