Ancestral human/hominen head hair is
Ancestral human/hominen head hair is
not Afro, Pauli (hominen???).
Afro hair is very derived.
Ancestral human/hominen head hair is
most unusual. It could be called
'extraordinary'. No other mammal has
anything like it.
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.
