yo this was really interesting LMAO at us being the most sexual creatures on the face of the planet
Examples of important aspects of human psychology which are unique & have evolutionary explanations
There are several aspects of human psychology which make homo sapiens stand apart from the other animals, and which attract much of the focus of those interested in evolutionary psychology:
human intellectual capacity - overall brain size, large frontal cortex, more convolutions, etc. all imply that a greater capacity to process information have been arguably the most dominant psychological characteristic selected for during the evolution of the human species
the sophisticated use of language - interestingly, humans seem to come pre-wired to learn language, but not with a pre-set language. During the remarkable period of neural plasticity during a child's early years, the child has a greater capacity for acquiring language that at any other period of his/her life.
capacity for emotion and affect - humans are fundamentally emotional animals, experiencing great heights of ecstasy and depths of depression. Compared to other animals, humans are both more likely to have excesses of joy (e.g. manic depression) and excesses of sadness (e.g., unipolar depression). No other animals are known to intentionally kill themselves. Humans are the only animals known to exhibit such destructive tendencies towards their surrounding environment and fellow members of their species. On the other hand, humans also display at times some remarkably altruistic behaviors which, on the surface, may not seem particularly adaptive.
complex courting & sexual behaviors - humans are the only animal, it seems, which are so addicted to sex, even when it doesn't seem to be for reproductive purposes; human females are the only primates to have permanently engorged breasts, and the male penis is proportionately larger than in any other species. Did you know that the most common word searched for on the net is "sex", closely followed by "porn" and other related words (to see a full list, go to

It seems that the sexual drive in humans interacts with the large intellectual capacity, the sophisticated use of language (think of all the love poetry out there), the drive to care (and the need to care for offspring for a long-time), and the capacity for emotion. No other animals exhibit the complex sexual disorders and deviations evident in humans. There is considerable examination of human aggression & violence, including sexual aggression such as rape, within evolutionary psychology.
