Just about all DNA tests (FamilyTree DNA, AncestryDNA, 23andMe, etc.) I have taken as shown me to people 100% East Asian, which is no surprise. I am of Taiwanese background (Taiwanese-American) with ancestry from 8-9 generations ago from Fujian Province, China (southeastern China) who moved to Taiwan. Hence, I am predominately Southern Han Chinese in ancestry. But, I have transferred data to places like DNA.Land, WeGene and Gedmatch to see further breakdown. That was what I was interested in. The Han people in China are not "pure." They are though mostly 100% East Asian, but mix of various groups. For example, my Southern Han ancestry is really a mix of Central Plains Han (Sino-Tibetan people) who moved south and intermarried with non-Han aborigines of Southern China such as Daic People, She People, Miao/Hmong people. When I transferred my 23andMe and AncestryDNA raw data to WeGene, it confirmed that I am a mix of Southern Han, Northern Han, Miao people, Daic People and even some Taiwanese Austronesian. Yes, these people are all East Asian. So, from a continental standpoint my ancestry is virtually all from East and Southeast Asia. But, a mix of different people groups within this region.

With power comes responsibility and given the nasty history of eugenics some of those whacks might not be so whacky in being leary of science that are done by flawed and imperfect human beings.

The Human Genome Project has associated many mutant genes with physical ailments and the genetic basis of certain behavioral characteristics is being seriously discussed. In the 1920s and 1930s, advocates for eugenics claimed that genes influenced human behavior, but with no valid evidence. In Germany the Nazis adopted their ideas to justify violent anti-semitism. In this new, expanded edition of the English translation of his compelling book T f6;dliche Wissenschaft, the distinguished German geneticist Benno M fc;ller-Hill documents the long-suppressed collusion of eugenics and racist politics which resulted in the mass murder of millions. In a new Afterword, he warns against the misuse today of newly emerging knowledge about human heredity. In an accompanying essay, Nobel Laureate James D. Watson, an architect of this new era of genetics, vividly describes a recent visit to Berlin and his impressions of the legacy of eugenics in German science.

Quote:
In the wake of the sequencing of the human genome in the early 2000s, genome pioneers and social scientists alike called for an end to the use of race as a variable in genetic research (1, 2). Unfortunately, by some measures, the use of race as a biological category has increased in the postgenomic age (3). Although inconsistent definition and use has been a chief problem with the race concept, it has historically been used as a taxonomic categorization based on common hereditary traits (such as skin color) to elucidate the relationship between our ancestry and our genes. We believe the use of biological concepts of race in human genetic research—so disputed and so mired in confusion—is problematic at best and harmful at worst. It is time for biologists to find a better way.

I also suggest reading the Zionist critic Franz Boaz: Anthropologists as Spies.

Most white Americans are purely European...much to their dismay.

...and a lot of black people come close.

Very true.

It probably depends on how you define close... Black people in the US are somewhere between 17-26% European in DNA. Not what I'd call close, then of course I guess it depends on what you mean by "a lot" too.

False. Africa is the most genetically diverse place in the world. This is consistent with all the other evidence that suggests mankind originated there:

etc. Plenty of data out there.

Phenotype diversity is not the same thing as genetic diversity.

A large percentage of American blacks and West-Indians are well over 90% African.

Please cite your source. All studies I've seen have shown the average European DNA for African Americans are again between 17% (the most recent study that is probably the most accurate) to 26% (an older 23andme study, this data used in the newer study but probably biased towards African Americans with more European DNA).

Here's the newest study:

PLOS Genetics: The Great Migration and African-American Genomic Diversity

Quote:
An estimated 82.1% of ancestors to African-Americans lived in Africa prior to the advent of transatlantic travel, 16.7% in Europe, and 1.2% in the Americas, with increased African ancestry in the southern United States compared to the North and West. Combining demographic models of ancestry and those of relatedness suggests that admixture occurred predominantly in the South prior to the Civil War and that ancestry-biased migration is responsible for regional differences in ancestry.
That's obviously the the average, meaning there are plenty of people above and below that 16.7% of European DNA. The study slices the data lot of ways but I'm not sure they show anything to reveal the amount of African Americans with "well over" 90% African DNA... They also don't include the median ancestry breakdown. With that said depending on what you define as "a large percentage" I think you are likely wrong... again depending on how you define "a large percentage."

I am sure that I am 100% white, and so is the majority of Europeans.
This to me is kind of a strange question.

Saying "pure" has racial connotations but it is very common on dna tests for people to be 100% European and even 100%British Isles. Most people appear to want to have some "exotic" ancestry and are often disappointed when they don't. It is very common for Americans to be very disappointed if they don't have some Native American ancestry showing up in their dna tests.

I believe that Edmund S. Morgan's book American Slavery, American Freedom: The Ordeal of Colonial Virginia has some material on this.

Mulattoes were more expensive, they could work in house tasks, etc. (house n-word). That is why most AA have probably more Anglo Saxon blood than recent immigrants.

The history of North America is not so short, during the 17th and 18th century, blacks and Indians were accepted couple as most white female died....more so in the outback, that was all the continent.

People lived in encampments, away from bible thumpers and "christian families" that were the ones that messed the continent.
