Scientists now agree
The development
Of separate races
Began around
50,000 years ago
When modern humans
Migrated out of Africa.

Dark skin pigmentation
Was and remains
A protective force
Against ultraviolet rays.

But as humans moved
Further north
Dark skin blocked
Too much sunlight
And reduced the
Natural production
Of Vitamin D
In our deep skin

Lighter skin people
Faired better
In Europe and China.

For those who
Migrated to South America
And southern India
Darker skin
Once again
Protected them
From the Sun.
