Could balding be considered a form of evolution?

I have watched a segment on lice through Nova and they stated that once there was just a single form of body lice on apes or early stages of humans. Once humans started losing hair the lice split one moved up to the head and became head lice and the other moved down to the pelvic region which becames crabs. The torso and upper body began to lose hair due to warmth and skin protection because these creatures had figured out how to make and wear clothing. By determining how far back the two different lice split from one was around the time we determined when our species started wearing clothing. Knowing that I am curious if balding is actually a form of evolution? We are wearing more hats not just for protection but for style so now our heads are staying more protected and warm therefore the need for hair is becoming less and less and over time it would seem to me the hair would eventually fade out on the head. Any thoughts?

    Jul 10 2013: I would like to believe it's evolutionary....
  • Jul 9 2013: I think it is possible that balding is becoming more common due to women preferences.

    Preferential mating characteristics are not necessarily related to survival fitness, as shown by the birds.

    It is possible that baldness is connected to high testosterone, and that high testosterone causes other affects that females find attractive, so that the baldness is just a side affect.

    Just a guess. Maybe its just a natural fluctuation over time, explained by probability and statistics. Ten years from now we might be wondering why there are so many redheads around town.
    • Jul 21 2013: Thats a GREAT excuse... :)

      But on the vast plains of Africa, ancestors to us all, the Lion with the biggest Mane wins :)

      Jul 22 2013: One of the most common misunderstandings about evolution is that the phrase "survival of the fittest" means survival of fit individuals. It does mean that to a degree (the unfit will not succeed in leaving offspring), but it really means survival of the best adapted (fittest) genes, which in turn leads to survival of the species. The pairs that leave most surviving and breeding offspring contribute most genetically to the future of the species, and their genetic traits will in time dominate. But as conditions change over time, genes that were adaptive earlier can be disadvantageous in the new environment, and entirely different traits may become the "fittest". Thus there's no clear direction to evolution, which is typically directed by the stress of environmental factors.

  • Jul 21 2013: Interesting, thanks for the source, I'll check it out!

    Haha nice abc XYZ thanks lol
  • Jul 13 2013: I would say balding as to I am only 25 and I know many other people as well but that is only in my perspective, that is a good question though, interesting.
  • Jul 13 2013: Is balding more common, or are old men more common?
  • Jul 9 2013: Thank you guys for the input, I've known about it genetically, but as I said after watching that segment on Nova, it made me ask questions.
