• Question 2

Approximately when did our human ancestors start to lose their body hair? When did they start to wear clothing? What evidence have researchers used to study each of these? (Note: make sure you state two specific examples of evidence -- one for hair loss and one for the adoption of clothing.)
Selected Answer: Our human ancestors started to lose their body hair about 3 million years ago. We know this because it is about the time the head louse and the pubic louse diverged into seperate species. This is due to genetic drift.
They started to wear clothing 170,000 years ago. Researchers used molecular clock dating to see when the clothing louse species diverged from head lice. Clothing louse would need clothing to evolve, so this is about the time humans began wearing it. [Show Less]
