The Great Afrikan Migrations was, 4 massive movements of people, that happened in progressive stages. The first three stages were by choice, the last being the forced due to the european slave trade. The results of these migrations is Afrikan and Afrikoid people living all over the earth, as well as remnants of Afrikan culture in embedded in different societies. Another consequence was the partial depopulation of West Afrika during the 500 years of the European Slave Trade.
Origin of Humanity
According to contemporary archaeologists, Afrocentric scholars , and paleontologists, modern humans or homo sapiens came into existence around 200,000 years ago in central east Afrika . In the area of present day Uganda, Kenya, Tanzania and Rwanda. They lived in central Afrika for around 130,000 years. In this time, these Early Afrikans were able to accomplish many firsts amongst humans. As eloquently spoken by great scholars such as John Henrik Clarke, and Molefi Asante, these Afrikans were the first humans to make tools, the first to hunt, the first to cross a river, the first to put a seed in the ground and make food, the first to build a shelter, and a slew of other firsts. They would go on to build on the foundation of these firsts, creating civilization and beginning the forward movement of human progression.  Following the origin, humans spread throughout the continent of Afrika
First Migration: Mt. Toba Eruption
Around 70,000 years ago there was a great volcano eruption in Indonesia. It is theorized that this eruption was so catastrophic that it deforested a lot of the planet.. This major change in environment had a major effect on humanity. It's hypothesized that the global population of humans droped to about 10,000. Most of the humans would have survived in very isolated tropical pockets in equatorial Afrika. Most of the other people (namely the homo-sapians, homo-neanderthals, homo-erectus, etc on Earth probably perished. This catastrophe lasted for thousands of years, and in looking for food, many Afrikans would have ventured out of Afrika, looking for food, and more comfortable environments than the deserts that would have been created. Studying human dna from around the world, geneticists have found that there was indeed an event 70,000 years ago that caused our genetic material to bottle neck which basically means that at one time there was a great amount a humans with diver genetics, and today there is only an array of 10,000, somewhat unrelated groups.
