That still doesn't explain why people sleep less.

  Yes it does. Modern humans have so many more things to do than hunter gatherers or monkeys. Monkeys can't engage in cocaine fueled raves til 6am, work the night shift at a nuclear plant, or pull an all-nighter to pass their organic chemistry mid term. They can't stay awake till 4am watching anime.

    Which of those things is done by “San hunter-gatherers of Namibia” when they sleep under the stars?
