People have little fur probably because we are aquatic apes. Our body fat composition is also consistent with being a semi-aquatic animal. Our young have swimming instincts. Breath holding. I'd say it's most likely we developed in a now dried up inland sea in north east Africa.
$this->bbcode_second_pass_quote('', 'O')ther mammals have moved from terrestrial to aquatic habitation. That a great ape made such a change is not unique or unpredictable in the history of the mammalian experience. Food in a warm shallow inland sea would have been abundant and is known to be productive of growth and change. Large aquatic predators probably did not exist. Then about 2 million years ago, our ancestors left aquatic life and returned to terrestrial habitation as the inland sea dried up. Our past can then be described as pre-aquatic, aquatic, and post-aquatic.

- The appendix purpose is to hold good bacteria between bouts of diarrhea, which is a great advantage. But since it's purpose to hold bacteria, that's probably why they occasionally become infected.
- Wisdom teeth can have some purpose as a tooth, however they also function as a repository of stem cells. So wisdom teeth probably have multiple advantages including probably improving healing ability.
