Discover your exact phenotype in 3D—completely free. 🧬
I built PhenoPlot, a metric-based physical anthropology calculator that uses custom coordinates from craniofacial landmarks. No facial photos or raw DNA data needed.

It seems like you have a fundamentally incorrect view of both the contemporary phenotype community and of basic human anthropology/biology. There are definitely some points to clarify ⬇️

3. These phenotypes, formed through the biological processes and bottlenecks still appear in modern people due to pleiotropy and linkage disequilibrium which causes some of these traits to come in "chunks" - this is of course not always true though.

Neolithic-Bronze Age qpAdm model of 3 Pre-Norman Medieval Gaelic Irish samples (665AD-1150AD)
︀︀This roughly adds up to 55% Steppe-like DNA, 33% Neolithic Farmer and 12% Western Hunter Gatherer.
︀︀This also proves my theory of the Irish being more Megalithic local EEF.

qpAdm breakdown of 15 Proto-Germanic Jastorf samples from Jutland (412BC-1CE) with their modern distances.
THE JASTORF CULTURE
In 600bc, the Proto-Germanics emerge out of Northern Germany and migrate in every direction, possibly reaching as far as the Netherlands and Romania in a few hundred years.
Full-Res and related Threads below ⬇️
The Jastorf Culture evolves out of various Initial Iron Age cultures on the Lower-Elbe with heavy La-Tene influence. After 200bc, it starts to Transition into the Histsorically Attested groups such as the Cimbri, Teutones, Suebi, Ingvaeones, Irminones, Lugians and Bastarnae.

Great tool to get a good idea of your phenotype, very cheap too.

A potentially better model for Proto Nordid, they require an Eastern Mediterranid source because of their high vaults (tall skulls) relative to EHGs.
For this it chose Pontid and Iranid.

Dalofaelid isn't a perfect proxy for the EHG/Pre Mediterranid phenotype however, its just simply the best out of the options.
For a perfect proxy I would suggest looking to John Nordid:

For reference here are some Nordid types using this model:
Proto Nordid = Official Yamnaya/WSH phenotype
Hallstatt = Unetice, Urnfield, Hallstatt phenotype
Keltic Nordid = La Tene, British MBA-IA, France IA phenotype
This is pretty cool, I thought about making a special file for ancestral populations, the major problem would be divergence though.
This is a rather smart workaround though because the samples you used are the most representative modern phenotypes of each ancestral population.
The Scandinavian Viking Phenotype: Trønder ⚔️
Rugged jawlines, high stature & narrower features (Common across Norway/Sweden).
PhenoPlot NNLS model (89.2% fit):
• 55.6% Brunn
• 23.5% Hallstatt
• 20.9% Proto-Nordid

The Anglo-Saxon phenotype, characterized by its light pigmentation, robust but harmonious features and prominent cheekbones was described as and now confirmed to be mix of Nordic and Cro-Magnon remains by: phenoplot.streamlit.app/
It's most common in North-Western Europe.
I added facial morphs to the PhenoPlot PCA to make it easier to visualize.

Yes, the axes capture environmental adaptation.
• Gobid (Top Left): Extreme cold-adaption & lighter pigmentation
• Proto-Nordid (Bottom Left): Temperate-adaption & light pigmentation
• Bambutid (Far Right): Extreme tropical-adaption & dark
