Race/Ethnicity Statistics and Research Megathread

Because they spent some time in Imperial Italy before moving to Central and Eastern Europe, and intermixed with local Italians (more than they did with non-Italians). Ashkenazi Jews can be modeled as 50% Levantine and 50% European. Most of their European heritage is from Roman-era Italians. Roman-era ancestry is more preserved in Southern Italians than in Northern Italians due to endogamy.

Levantine ancestry also shifts the Ashkenazi and Sephardic populations southwards, so admixture with Germanics and Slavs doesn't make them more Germanic or Slavic-like.
We wuz Romans?
 
Here are my autistic theories (I am an amateur racist btw):

- Homo Erectus left Africa and traveled extensively, settling Europe and Asia.

- Erectus branched out in Asia, evolving into Asian homo Erectus

- Australnesians (aboriginal Australians, natives of the Philippines/Thailand/etc) are all Denisovan/ Asian homo erectus hybrids.

- eurasians are Neanderthals/modern human hybrids.

- eurasians spread through the Middle East and asia (and eventually the Americas)

- Indians/pakistanis/bangladeshis are Eurasian/australnesian hybrids.

- CJK Asians are Eurasian/denisovan hybrids.

- Thai, Filipinos, etc are australnesian/CJK hybrids

- Africans are, actually, really diverse. They’re everything from pygmies to the KhoiSan to the biblical Kushites (Ethiopians). Some of them are super primitive, especially those in Ghana that are “20% ghost hominid” — yikes.

I remember reading that Hawaii had some of the highest literacy rates in the world after the introduction of the Latin alphabet and the Native Hawaiians were so industrious and hard-working that the colonizing whites were astounded they didn’t want to take Sundays off for church.
Google says the first claim is true, but second is backwards:
The second part of the claim gets the dynamic entirely backward. The historical reality regarding Sundays (Lā Kāpaki) and labor was the exact opposite:
  • The Missionary Concept of Time: Western missionaries and white capitalists introduced the rigid, Western concepts of the 7-day work week, the industrial work ethic, and the strict enforcement of the Sabbath (resting on Sunday).
  • The Hawaiian Response: Native Hawaiians operated on a lunar calendar (Anahulu system) tied to agricultural, fishing, and ecological cycles rather than a strict weekly clock. They did not inherently view daily, repetitive industrial labor as a moral virtue in the way Calvinist missionaries did.
  • The Conflict: White colonizers and plantation owners frequently complained that Native Hawaiians were "lazy" or "unindustrious" because they refused to adhere to grueling, continuous plantation schedules.
  • The Sabbath Laws: It was actually the white missionaries who, with the backing of converted Hawaiian chiefs (Aliʻi), instituted strict laws banning work, travel, and recreation on Sundays to force people to attend church.
White business owners were frustrated that Hawaiians prioritized their traditional lifestyle, community, and subsistence farming over working on Western sugar plantations—which ultimately led those white businessmen to import cheaper indentured labor from China, Japan, and Portugal.
Ah, those look familiar @Gaystapo
 
TL;DR blacks have different microbes in their mouths than whites.

Title:

Deep Sequencing Identifies Ethnicity-Specific Bacterial Signatures in the Oral Microbiome​


Abstract:
Oral infections have a strong ethnic predilection; suggesting that ethnicity is a critical determinant of oral microbial colonization. Dental plaque and saliva samples from 192 subjects belonging to four major ethnicities in the United States were analyzed using terminal restriction fragment length polymorphism (t-RFLP) and 16S pyrosequencing. Ethnicity-specific clustering of microbial communities was apparent in saliva and subgingival biofilms, and a machine-learning classifier was capable of identifying an individual’s ethnicity from subgingival microbial signatures. The classifier identified African Americans with a 100% sensitivity and 74% specificity and Caucasians with a 50% sensitivity and 91% specificity. The data demonstrates a significant association between ethnic affiliation and the composition of the oral microbiome; to the extent that these microbial signatures appear to be capable of discriminating between ethnicities.

Discussion: I wonder how this one would be spun by race-denialists into a "social construct" or to it being the results of "oppression" - even when they live among us and eat the same goyslop, their bodies are so different that we can't host the same bacteria as each other!

As an aside, I wonder if this also explains the prevalence of bacterial vaginosis among black females ...at least, maybe partially explains it - the other explanation being promiscuity and poor hygiene.
 
Albeit all these details, The European cluster is very homogenous overall: the second most homogenous population cluster in the world, in fact (only East Asians are less genetically diverse). The most diverse region in the world, containing 90% of human genetic diversity, is Subsaharan Africa
Odd how yet these two populations accounted for most civilisations.
We wuz Romans?
Hadrian zutted them, oy vey.

A lot like the conspiracy theory one, our research just had it be a later hominid than erectus.

African negroes for the most part do not have denisovan or neanderthal dna. Mutt Niggers on the other hand must have gotten some massa loads up in them, so they likely have both and the ghost hominid as well. Niggers also have a monkey like jaw structure that is more prominent or at least universal than with Negroes.
TL;DR blacks have different microbes in their mouths than whites.

Washin yer teeefs is rayciss! Shieeeet!
Maybe they will evolve a bacteria that is really good on thriving on meth, kool aid and fried chickunz.

They did a similar study with the vaginal
pH. They found similar racial stratifying.

There was an attempt at a deboonking where they looked at the vaginal micro biome:


There is no significant difference in vaginal pH level between black and white women after controlling for differences in confounding factors, particularly vaginal flora.

Which is like… worse than just having a different pH, IMO. Not to mention, the difference in bacteria is probably CAUSED by the difference in pH. But whatever, scientists these days are all either retarded or engaging in willful obfuscation for political reasons.
 
ADME genes (Absorption, Distribution, Metabolism, and Excretion) are those that code for enzymes that are responsible for, among other things, breaking down pharmaceutical drugs. One of the most important is Cytochrome P450 (CYP450) - a large family of heme-containing enzymes.

Africans have a completely different family of ADME genes and make completely different CYP450 enzymes than Europeans: https://www.sciencedirect.com/science/article/pii/S2352396417300762

Note that Asians have their own versions as well. This is not surprising to anyone who believe there are multiple human species (or at least subspecies) in existence.

What all this means is that certain drugs will have increased or decreased efficacy, and work at higher or lower dosage in Africans, Asians, and Europeans.
