The out of africa theory has been falling apart at the seams for decades with many people calling it officially debunked. There are archeological digs and finds all over the world with presence of human remains dating back to 150,000 - 250,000 years depending on which dig you're looking at. There is already a plethora of evidence stored in museum basements around the world labeled as anomalies, or otherwise purposely Mislabeled. Hard physical evidence that has up to this day been deliberately ignored or secreted away as it just did not fit the accepted and dictated narrative espoused by the Scientific social circles of the day.
Why was this theory put forward back in 1989? The answer is obvious: politics!
During that time period, racial inclination was fundamentally different than today and for politically reasons, the theory was proposed by Allan Wilson who posited the idea of the Out of Africa hypothesis based on stilted and flimsy archeological evidence. He ended up having to recant his theory after further study of the mtDNA of native indigenous people in Australia which the results concluded that Aboriginals have inhabited Australia for over 400,000 years.
So why is the theory still circulating around?
The answer is twofold. If the racial inclination in 2017 existed back in decades ago (equality and interracial marriages), then the theory would have been quickly forgotten but it continued to stay mainstream for political reasons such as giving black people equal rights. The second and perhaps the more prevalent reason for why the theory continued to circulate is because of .... ego.
After all, what greatly acknowledged and respected Professor of the day would want to see their life’s long work and theory’s built over many decades proven wrong towards the end of their life ? And what up and coming student of theirs would want to show their mentor and tutor to be wrong (and still wish to keep their position)? And what scientific group or institution would want to also admit that everything that they had (and have) relied upon promoted and published over many decades in a globally recognized field , all their funding, all their apparent great work….was wrong ?
Those archeological digs I mentioned above, well and truly exist. For example, Hueyatlaco is an archeological site in the Valsequillo Basin near the city of Puebla, Mexico. The archeologists there recorded the remains of human settlement through carbon dating which put them at around 250,000 years. Due to politics, the dig was covered up and the archeologists had a gag order to be silent.
All these sites predate the Out of Africa theory.
Africans (Homo Sapiens) who wore barest of animal skin pelts around the groin area and harnessing basic slings could not have migrated north into Europe and eventually East for the simple reason that the Earth of that era was undergoing a major Ice Age with temperatures reaching low as -45 Degrees. Pretty much everything north of Egypt was covered in snow which makes it impossible for African natives to migrate north. What's interesting is that people keep ignoring the fact that even by some miracle, Africans traveled all the way down to Australia, the primitives would have had to find away to traverse the expanse of an endless sea to reach Australia which we know did not happen given the sporadic level of technology of that era.
This is only compounded by the larger travesty that ignorant "academic" people claim that the Out of Africa theory is true and originally said that this occurred 10,000 years ago. This theory was revised after some new evidence came to light and stated that instead of 10,000 years ago, it was 50,000 years ago. After some more evidence, instead of 50,000 years ago, it was 120,000 years ago. They keep trying to revise it to keep the theory mainstream but the sad fact is, there is no way African's could have populated Australia 120,000 years ago when it was already being inhabited by Aboriginals almost half a million years ago (400,000).
This does not even account for the mutation of mtDNA of different races as a result of exposure to diseases, sexually transmitted diseases, plagues, food and drink poisoning in parts of the world which did not originate from Africa. For example, common colds that were native to England were harmless to Europeans 200 years ago but these common colds were absolutely deadly to Aboriginals in Australia when the white settlements began. This because Aboriginals didn't have any build up of immunity to common colds and flues and proved deadly to them.
The Out of Africa theory is becoming more of a joke by the day, and is now looking more like a Punch drunk old boxer as new discovery’s keep peeling away the inconsistency of it and inconvenient FACTS just keep hammering it with new empirical evidence.
