If we all originate from Africa were humans all black at one time? Imagine a group of early humans, living in the lush African Champaign. They were the first ultramodern humans, and like all living effects, they were shaped by their terrain. The bright African sun was violent and constant, so natural selection favored those who had darker skin. This is because darker skin provides natural protection against dangerous UV shafts, which is especially important near the ambit.
But also commodity fascinating happed, a small group of these early humans decided to leave the safety of their African home and explore the world. They walked and walked, for thousands of long hauls, through comeuppance and over mountains, until they eventually reached new lands. These new lands had lower sun and further shadows, making it delicate to get the vitamin D they demanded to survive.
But, as luck would have it, natural selection formerly again came to the deliverance. The skin of these early humans began to lighten, allowing them to produce further vitamin D and thrive in their new homes.
And so it goes, as the generations passed, these early humans continued to resettle and acclimatize to their new surroundings. Their skin grew lighter and lighter, until they were unrecognizable from their African ancestors. This is how our ancient mortal family tree came to have branches of all different colors, from the darkest ebony to the palest demitasse.
It’s worth noting that the conception of” race” is a social construct, with no real natural or scientific base. Humans have been evolving and migrating for thousands of times, creating an inconceivable diversity of inheritable variation within the population, this variation doesn’t conform to traditional ethnical orders.
Our skin color is just one of the numerous fascinating ways that we’re all connected through our combined history.
