out of africa has always been a politically motivated fake theory promoted by academic frauds

>>15471162
Careful, that one guy is going to join this thread and launch into a 30 post tirade about how out of Africa was proven by Lewontin and how only racists could possibly question it

>>15471022
>Although the theory that H. sapiens originated in one local population and then spread has been the dominant interpretation for some time, according to the authors it does not fit well with either the archaeological or fossil evidence. Indeed, the physical record indicates a relatively synchronous (on a geological time scale) appearance of both artifacts and fossils attributable to modern humans across a wide area of Africa, rather than a single point of origin followed by a gradual dispersal.
All this is saying is that humans arose in a wider area of Africa rather than a single place in Africa. Its not saying humans aren't from Africa.

>>15471022
>This finding reinforces the view that current physical variations between populations are superficial and merely represent the temporary state of a constant shuffling of populations that has been ongoing for hundreds of thousands of years.
lmao literally desperate to force in a politically correct narrative.

doesn't mean anything at all and he's just pretending that humans just popped up all across africa because they were kangz

What he's saying doesn't make a lick of sense. How can a species appear simultaneously at multiple places.
What happened clearly is that at ONE place H. Sapiens was born in a tribe of a previous evolutionary phase. He was more violent and intelligent and taught them to genocide all the other tribes successfully. He raped his way across the continent and created H. Sapiens halfies which literally mutted the previous H. iteration until they became dominant. This has probably been how the human race developed since H. Erectus because that's our natural behavior
>be smarter than the rest
>genocide male threats
>rape all the women
>lol
>lmao
>repeat
He is correct that this took multiple iterations of new H. slowly developing into the most advanced version of H. but saying that outright will be admitting that H. from Africa are probably less intelligent than those who managed to get the fuck out to Europe and interbreed with Neanderthals or to Asia.
He's doing his best not to justify scientific racism but it's failing.

>>15471193
>How can a species appear simultaneously at multiple places
Different species could.

The debunking of the out of Africa theory is itself debunked by Danielle Twum's journey to America to become the one of nation's most famous and successful scientists. There is now a statue of Dr. Twum in Washington D.C. while there are no statues of any native born American scientists in the city at all, so clearly civilization emanates from Africa

This is one of those political popsci theories that everyone already knew was fake to begin with, nice to see it made official that the professionals have been lying to us about this all these years, too bad there is no consequences for their lying and waste of resources

>>15471022
Out of Africa Theory is only believed in the West. Asian people don't believe it and never will. There is even fossil evidence showing a continuous line of Homo erectus evolving into modern Asians and no fossil evidence of Africans displacing indigenous populations. Once China economically surpasses the West, the Out of Africa Theory will be discredited.

>>15471678
Ok so homo erectus emerged from africa, and evolved separately into the various races. Why is that controversial?

>>15471678
Two more weeks until China supplants the decadent wect as the centre of scientific achievement

>centre of scientific achievement
Now show the patents made outside the academic scammer world.

>>15471022
Well, that does bolster the case that the rest of the world strongly diverged from sub-Saharan African homo-sapiens about 100,000 years ago, and the common ancestry is rather distant.

>>15471717
LOL.

You should study Genetics or Evolutionary Biology before speaking out your anus.

>>15471172
I think the point the OP is trying to make is that since humans arose in a wider area of Africa then it is also plausible that they arose in the wider area of the world and that therefore the Out of Africa theory is wrong. This is similar to the concept that if you can see one second into the future, you can see years into the future, as when something that was formerly deemed impossible becomes possible, it is now possible on a wide range.

>>15471678
>and no fossil evidence of Africans displacing indigenous populations
Madagascar was settled by Asians, it seems more likely that Africans evolved from Asians than the other way around

>>15472752
They have "ghost DNA" that sets them apart from all other hominids, so they're likely a different species with a common ancestor in the distant past. Just like Denisovans (aborigines).

>>15471022
>relatively synchronous (on a geological time scale)
I'm relatively synchronous with Pharaoh Khufu (on a geological time scale).

>>15472752
> it seems more likely that Africans evolved from Asians than the other way around
This is well known.

>>15471724
came to ask this. i've always wondered why the out-of-africa hypothesis doesn't also imply that africans are lesser evolved and more closely related to homo erectus or chimps or whatever. like, if africans are the starting point, and white europeans or asians theoretically descended from that point, then wouldn't africans be like prototype humans?

Here’s a question: is it easier for skin pigmentation to become darker or lighter over generations? Like, is there a “path of least resistance” for the change in color?

Uneducated geographer here.
Did Africa exist back there?

That's definitely not what anything in the Nature article is saying. Given the disconnect between the claimed title and image, and the post text, OP is obviously trolling the racists. The body text even explicitly refutes population differences beyond the superficial and at least one got assmad about it >>15471193

>>15473533
You have to read between the lines a little. Everyone has to pretend that there's nothing genetic involved to toe the line, usually in closing statements, but the research always stands on its own merits proving otherwise.

>>15473551
You had to make up an entire narrative based on my fairly obvious commentary that a few lines making the mandatory CYA statements to get past peer review don't invalidate the actual research.

Jessie what the fuck are you talking about?

People lived in Africa, but in more areas of African than we assumed
How does this "debunk" the theory?

This is probably my biggest problem with /sci/. This board whines endlessly about how bias academia is, but ironically ends up being just as bias.

>>15473569

opinion automatically discarded when you don't know the word "biased"

>>15473569
>People lived in Africa, but in more areas of African than we assumed
>How does this "debunk" the theory?
The apparently sudden appearance of tool use around the same historical time in a multitude of areas suggests an already fully realized hominid species migrating into Africa in historic timescales rather than originating there and slowly developing over evolutionary timescales.

>>15473574
what kind of tools and how long ago?

>>15473598
Discussed in the article.

>>15473601
the op article? nothing about tools is in there what are you talking about?

>>15473603
Oh the OP didn't actually link the article he's quoting.

There is no evidence anywhere which suggests that the primates which developed into homo habilis were of African origin. It could just as easily have been Asian or European primates. Somewhere in the old world is the only thing the available evidence points to.

>>15473606
the article he is quoting doesn't talk about tools either what are you talking about???

>>15472887
it isn't the case, human ancestry is not african, the out of africa theory is incorrect

>>15473551
You are a moron

My theory is that there was simultaneous evolution. There were 3 main types of cavemen. When man left africa, he was still a caveman, it was the caveman that became distinct by region, and then evolved into the human we know today. White, black and yellow ones. All became human in their own regions of earth over similar periods of time. They mixed somewhat over time, not much. Some did not mix at all, like the subsaharan desert tribes.

>>15473890
I bet it came to you in a dream because that's how science works right
>>>/x/

>>15473890
blacks and leftoids are obviously a different species, an inferior one.

>>15471022
While mildly interresting. Whats the point.
Even if all humans originated from a single tribe in africa that doesnt stop evolution from creating different sub species after the Population splits.
It has no bearing on my opinion on modern populations

>>15473890
>it was the caveman that became distinct by region, and then evolved into the human we know today
This is the prevailing theory, not just yours.

>>15473890
>When man left africa
Humanity did not evolve in Africa

The humans eventually settled in Africa bred and continue to breed with chimpanzees, that is how the negro race came to be
https://guardian.ng/news/genetic-makeup-of-12-year-old-angolan-boy-in-dispute/
The genetic makeup of a 12-year-old Angolan, boy is now disputed by experts after his deceased mother allegedly told him he is the offspring of a human-chimpanzee love affair, reports the Gazeta Nacional.

The story made national headlines and has unleashed an outpour of generosity towards Augusto Dembo, 12, who now lives with his uncle and aunt in the capital city of Luanda.

“S*xual relationships between humans and chimpanzees are fairly common in the region but this is the first time a pregnancy is officially reported, ”Dr. António Mendes of the Hospital Municipal do Luena doubted.

Angola President João Lourenço has already nicknamed the boy the “Angolan Miracle Child” as well as praising the young man as a “National treasure”, “a sign from God” and a “testament to the majesty and greatness of the Republic of Angola.”

This discovery could even challenge the basic foundations of modern science,” has even commented on the current Minister of Science and Technology, Maria Cândida Teixeira.

A spokesperson from the Parc national de Cameia commented on the news by saying that they sincerely regret the loss of Anita Dembo but also condemned “any inappropriate or s*xual acts with any animals in the park.”

“Any s*xual interaction between employees or visitors of the park with animals is not encouraged behavior under current park guidelines,” a spokesman for Parc national de Cameia told reporters.

As for the child’s mother, Anita Dembo, allegedly entertained an affair with a chimpanzee that endured for many years during her employment at the Parc national de Cameia where she has worked as a conservation officer since 1998.

The San Tribe of Africa looks like a perfect mix of Asian, black and white. Their DNA confirms them to be our purest and oldest race. Stop being a midwit. Not everything is political. The truth just is.

My point is that they were cavemen when they left Africa, not humans. Cavemen became humans in Asia, Europe, and Africa. There is no "out of africa" because we were not human when we left. It's just logical.

>>15477337
rofl imagine being so stupid you believe the figures of singapore and china holy shit what a shill

>>15477594
they didn't "leave africa", there is no evidence that supports the out of africa theory

>>15477337
In the mid 20th century Singapore has a reputation as one of the filthiest, most crime ridden, degenerate and amoral hellholes on the planet. All of that was cleaned up by strong leadership of one guy, Lee Kuan Yew. He did 100x more for Singapore than what Rudy Giuliani did for New York and Giuliani did an amazing job on New York, he took a trash dump and polished it sparking clean.

Why is /sci/ so bad at genetics
t. /his/

The paper outright confirms what it tried to disprove: archaic ancestry in modern human populations and extreme population structure. A population, called "stem", split from the ancestors of humans and Neanderthals over a million years ago and then at around 100 thousand years ago contributed to both South Africans and other humans but only AFTER they had split from one another. This to me tells that this population had survived 900 thousand years and it even survived up to the LSA as evidenced by West Africans receiving more of this ancestry later than other groups.

>>15476908

He can believe what he wants, but the San are blatantly the origin of the Asians (and all races) and their DNA proves it. Though some mixed more with neandertal than others.

>>15477594
>There is no "out of africa" because we were not human when we left. It's just logical.

This what we were when we left. All human DNA converges onto the San Tribe & diverges from it.

>>15479207
>>15479208
South Africans are just the first split and even so there might be some branches (as evidenced by the paper) that contributed to other populations) that split before them.

>>15471678
>Once China economically surpasses the West

kek, I kneel science sensei

they have azn dna as a result of mixing with the same azns that settled madagascar, you've got your story backwards, out of africa is a disproven theory

>>15480154
Madagascar is directly across the water form the former Hottentot part of Africa.

>>15479212
>when you see it

>>15480799
Combine that with the knowledge that the Malagasy are descended from experienced sailors from Borneo who had an oceanic trading culture, and you'll see why Asian DNA ended up in the region.

>>15472985
White are albinos, type c albinism if I remember

>>15480840
Where do people come up with nonsense like this? Whites are clearly not albino by any definition of that condition.

>>15480811
Hottentot presence is tens of thousands of years older than malagasy retard. They couldn't be more different from each other. Malagasy weren't even settled when the first Bantu migration started circa 3000bc. It's like relating melanesians to Negroes bases on the retarded description of colour alone when it's been shown that they are closer to Asians than Africans.
