Our Ancestors: One Human Family

Our Ancestors

Scientists all over the world have universally agreed that the earliest humans originated in East Africa and had dark skin. Whenever there is a study of the earliest human skeletal remains it is almost exclusively undertaken in the region of East Africa starting from the River Nile in Ethiopia through to Uganda all the way down to South East Africa.

The origin of dark skin comes from the chemical known as Melanin. All Humans have degrees of Melanin but if someone has excessive amounts of melanin in their skin, then they would have a dark complexion.

Melanin comes in three forms Eumelanin and Pheomelanin and Neuromelanin. Dark skin and hair are in the form of EUMELANIN. PHEOMELANIN causes red hair and pinkish skin.

Eumelanin helps protect against sun damage and UV rays, so if you lived near the equator where it’s always hot and there is lots of sun exposure, having eumelanin in your skin would have been a good adaptation to have.

There are a lot of theories about how humans became lighter in complexion and one popular one seems to be that because dark skin can act as a shield that prevents us from absorbing UV rays from the sun, as people migrated out of Africa towards the northern hemisphere, where there was far less sunlight and heat, the adaptation for skin to colder climates developed over a period of time. This is still a theory at the moment and evidence is still forthcoming to further support it.

Dark skinned Africans on the other hand are genetically related to the first humans. The first humans had dark skin which is referred to by some as ‘Black skin’ even though it in reality it is BROWN.

Once Dark-skinned Africans migrated out of Africa they evolved and became the various types of Humans we witness today.

Over time some of those dark skinned peoples who migrated to Europe adapted to their environment and became “White”. However Humans that remained in warmer climates, South Asia, Australia, South East Asia, and Africa remained “Black” or Brown.

The original Africans were very diverse in physical appearance as they are today. Some of them were extremely dark while others were medium brown…they had different hair textures, noses, lips and head shapes. This is why in Africa you can find all the global ‘racial’ features and that original blacks can be found in almost every region right across the planet earth.

Ancestral South Indians who originally inhabited much of the subcontinent some 20,000 to 30,000 years ago actually looked African. The proof of this lies off the East coast of India, on the Andaman and Nicobar islands.  The Andaman islands lie in the middle of Bay of Bengal east of India.

As one of Africa’s oldest cultural groups, the Khoisan are also the oldest inhabitants of southern Africa, where they have lived for at least 20,000 years. Genetic evidence suggests they are also one of the oldest peoples in the world and genetically the closest surviving people to the original Homo sapien “core” from which all human-beings emerged.
