AN IDEA WITH NO HAIR
I read something,
But I lost the magazine;
So I will try to reconstruct it…
We were once very furry,
But now have very little hair
On our bodies.
Most animals still have
A lot of hair or fur,
But for the larger beasts
That ever need to cool
A large mass.
It’s warmer now,
So even the naked elephant
Is no longer a Wooly Mammoth.
When eats and treats were abundant,
Our furry ancestors could just
Laze around, not exerting themselves;
But, when forest shrank,
‘We’ had to walk/run
Over long distances
To secure our prey and food,
And so some thick clogged hair
All over would not do so well for us.
Hair was thus selected out,
In conjunction with
The arrival of sweat glands
That could dump
12 liters a day.
We were pink underneath our fur,
This turning to black in the hot regions.
Hair on the head still works
To ward off the direct sun.
Via our new epidermal sweat glands,
We could increase
Our body and brain size
And exert ourselves more.
