  • Ancestral ('Afro') hair -- What's it for?

    From Paul Crowley@21:1/5 to All on Sat Jan 29 14:24:07 2022
    Ancestral human/hominen head hair is
    most unusual. It could be called
    'extraordinary'. No other mammal has
    anything like it. So what's it for?

    Two reasons for it have been proposed:
    A) Insulation of the head & brain against
    the heat of the sun;
    B) Insulation of the head & brain against
    cold -- when swimming in the sea.

    I suggest we can rule out (A) insulation
    against the sun. We all know what it
    takes to protect one's head here -- wear
    a hat, ideally a wide-brimmed one that
    will also protect the shoulders.

    A layer of good hair (not an Afro) will
    usually be adequate for the head. There
    is no need for anything the size of an
    Afro.

    Our ancestors have been capable of
    making hats, or some kind of head
    covering, for at least a few hundred
    thousand years. The material for this
    kind of straw hat is ubiquitous.

    So it's insulation of the brain against
    cold -- unless someone can come up
    with a better idea.

    Afro hair is very derived.

    How when and why would Afro hair
    have derived from some other kind
    of hair?

    The above is accurate and intelligently put forth if 'Ancestral' is replaced only with "African".
    Hominin hair was most like hominoid hair.

    Coiled hair is unique, derived from typical hominoid hair, under selection for sun protection (skin, eyes) with ventilation enabling scalp cooling via eccrine sweat, advantageous in tropics, not in temperate nor sub-arctic zones.

    The below is near-imbecile level thinking that no comment can repair.
