SKIN COLOUR
Our ancestors had nonpigmented skin with body hairs
Body hairs later depleted by sweat glands
This helped humans to hunt for food in sun
Evolution is slated to have begun.
Human skin colour dark brown to light hues
Depends on environment UV radiation genetics
Earliest humans near equator had dark skin
Migration to cold areas in North led to light skin.
Women lighter than men generally
Europe ladies darker than men mainly
That makes them absorb D Vitamin
To ease their labour pain.
Melanin induces skin colour
Palm and sole have shade lighter
Skin also gets tanned in sun light
Basically skin colour is genetic.
We may have different skin colours
We all come from same ancestors
Be they Arabs Africans or Mongolians
Light hued Europeans or Americans.
We may live in Northern part
We may be in Southern part
We may be natives of East or West
Remember we are all Indians first.
