Genetic Bucket Chain, Part 1

This is the story of how you and Inuk are almost certainly both direct descendants of Confucius.

NOTE: Yes, Julius Caesar was a poor choice, and Cleopatra is not much better. Their heirs may have been part of the 20% that we are NOT related to. Confucius, on the other hand, is much clearer.

Part 2 will be posted when I can finish it, probably on Saturday. My apologies for the sound quality, my microphone is in the slow process of death. I'm sure this one is riddled with math errors. Feel free to point them out.

"No evidence of Neandertal admixture in the mitochondrial genomes of early European modern humans and contemporary Europeans."
"Neandertals, the archaic human form documented in Eurasia until 29,000 years ago, share no mitochondrial haplotype with modern Europeans. "

You are very severely underestimating inbreeding. The

Neanderthal ancestry is found by analysing autosomal DNA, not mitochondrial DNA.

No North Asian autosomal markers whatsoever are found in African populations, for example. No 'Neanderthal' markers are found in Africans - even if those are not 'Neanderthal', they would have been present if there was interbreeding. Groups that end up dissimilar on IBS SNP analysis share no recent common ancestry.

@Humanophage

Factually false:

Am J Hum Genet. 2002 May; 70(5): 1197–1214.

"A Back Migration from Asia to Sub-Saharan Africa Is Supported by High-Resolution Analysis of Human Y-Chromosome Haplotypes"

You can read more if you research M207, which is now called UTY2. It is a lineage marker found in Central and Northern Asia, and also in some populations in Cameroon. Many Africans possess autosomal markers for the near East and Europe.

However, genetics is diluted over time ancestry is not.

@mphello Please rephrase terms like "identical ancestor point" in terms of existential and universal quantifiers and nodes and edges in graph theory. Thanks!

I LOVE THE MATH! DON'T LET UP ON THE MATH MODELING!

[anarksee]

Goolge Image the word "phylogenetic tree".

YES I read some similiar in a bbok

[squirrelywrath2]

I can only begin to imagine how you have time to keep up with so many comments on this stuff o.O

@MetroAdventures i LOVE how you say that but dont say why

[MetroAdventures]

It really bothers me that this video doesn't have more dislikes.... This is terrible science.

@C0nc0rdance Near east... NOT confucious.down to the Cape of Good Hope or to the Andaman islands...

Bais Bias Bias Bias! Isolated populations, man! Isolated populations!

Some tribes did not interbreed with Eurasian people for thousands of years!
