Cheddar Man, Mesolithic Britain

[Bellbeaking]

haak et al gave significantly more WHG to scotland than england (like 60% more), how can the distance be the same to england and scotland?

I uploaded him to DNA Land, let's see what they report, how much coffee did he drink, etc.

I have uploaded him to GEDmatch Genesis:

Cheddar Man England 7150 BC, GEDmatch Genesis kit number - NW6414429

Where did you get the raw file for this?

Segment threshold size will be adjusted dynamically between 200 and 400 SNPs
Minimum segment cM to be included in total = 1.0 cM
Mismatch-bunching Limit will be adjusted dynamically to 60 percent of the segment threshold size for any given segment.

Largest segment = 1.8 cM

Total Half-Match segments (HIR) = 6.1 cM (0.169 Pct)

4 shared segments found for this comparison.

488390 SNPs used for this comparison.

55.063 Pct SNPs are full identical

Great work!

Let me preface by saying, I'm new to this...

That being said, I really like your explanation of the SNPs and agree that his skin was likely intermediate.
We still dont know exactly what produces the level of pigmentation in every population.
I think it makes a lot of sense that Cheddar Man didnt have all of the components/genes that make up modern day European skin genetics.
This man had been out of Africa for 10,000 years less than us, and did not have the shared ancestry with modern Europeans (farmers and Yamnaya).

His relation to other hunter gatherer populations (Estonians) surely means that he may have looked similar to them in several ways, but had the darker skin of a population that was less mixed with other Eurasian gene pools. (Many of which probably selected for lighter skin simultaneously).

Doesnt lifestyle turn on or off genes which influence skin color?

True European native.

True European native.

brotha from anotha motha

[PaleoEuropean]

So where did the brown skin come from? Artistic licence?

He matches most with Saami people according to the heat map so he was probably one of the first instances of mixing with Siberians

[Bellbeaking]

rs1426654(G;G) ---> G is darker skin, modern Northern Europeans have A;A here
rs16891982(C;C) ---> C allele is darker skin, also 7x more likely to have black hair

Japs and Chinese have this genotype on both SNP's but are pale skinned. But then again our boy didn't have the Genes for light skin asians do have.

They almost certainly where not Blonde though, I am C;G (inherited from my Norman, North West Euro Side - only 3% of NW Euros are this) and my hair is black despite all the other genes for Blonde hair, (greek/welsh mother is light blonde haired). My siblings all have Blonde hair probably due to not having this allele. I think this is a powerful SNP. His hair was black like mine I think.

rs1408799(C;C) ---> C is lighter pigmentation & higher skin cancer risk in Europeans (per SNPedia)
rs1834640(A;A) --> associated with skin pigmentation (modern Europeans have A;A too)
rs12203592(T;T) ---> T associated with less tanning ability, common in Irish people
rs1015362(G;G) ---> G associated with less tanning ability, Sub-Saharans have A;A

Are you able to confirm that these are on Cheddar Man's DNA raw data? Interestingly the natural history museum has a download listing his pigmentation data but seems to have omitted what I have quoted.
