Five research punchlines — scan before you dive.

Genetic distance myths is a reference layer for the Peoples atlas: patterns you can check, not a podium for continents.
Each layer explains what the measure is, where it misleads, and how it connects to culture pages without racial ranking.
Demography and linguistics change; treat figures as era-bound.
Genetic distance myths overview
What Genetic distance myths measures and why it matters.
This layer exists to answer “where?” and “how connected?” without sliding into “who is better?”
Read it beside culture pages: tongues, cities and migrations are how peoples actually meet.
- Define the unit of measurement before coloring any map.
- Prefer gradients and networks over sealed continental boxes.
- Separate speaker counts, genetic metrics and cultural identity labels.
- Flag colonial and census distortions explicitly.
- Link out to diversity topics when biology is misused in public debate.
Layers
- What distance measures
Average allele-frequency differences — not souls, IQs or civilizations.
- Isolation by distance
Nearby peoples usually share more alleles; oceans and deserts add noise.
- Sampling tricks
Cherry-picked populations can fake tidy racial clusters.
- Within vs between
Most heterozygous diversity still sits inside local groups.
- Responsible use
Ancestry models can aid medicine without resurrecting race hierarchy charts.
How to read this map
Signals a careful reader looks for — and the traps that turn maps into myths.
Within-group variation dwarfs between
Revisiting Lewontin with modern data still undercuts folk race biology.
Medical ancestry ≠ census race
AIMs can aid some risk models — checkboxes often fail; precision language saves lives.
Online distance-chart propaganda
Extremist forums circulate FST tables as hate fuel — captions must refuse that reading.
Research, in plain language
Scholarly themes rewritten for curious readers — not paywalled jargon, and never a race ranking.
FST is not a race score
Genetic distance statistics measure differentiation; they do not rank cultures or intellect.
Takeaway A number isn’t a podium.
Within-group variation dwarfs between
Revisiting Lewontin’s insight with modern data still undercuts folk race biology.
Takeaway Most diversity is local.
Neighbor-joining trees misread as pedigrees of worth
Pretty trees tempt racist storytelling; branches are sampling artifacts too.
Takeaway Don’t worship the dendrogram.
Medical ancestry vs folk race
Ancestry-informative markers can aid some risk models; folk race checkboxes often fail.
Takeaway Precision language saves lives.
Online distance-chart propaganda
Extremists circulate genetic distance charts as hierarchy porn; this atlas layer names the con.
Takeaway Charts need captions against hate.

FAQ
Is this a ranking of peoples?
No. Atlas pages refuse superior/inferior framing.
How often are numbers updated?
When masters revise; UN and linguistic datasets move — check dates in prose.
Can I use this in class?
Yes, with attribution to Tool-Lifes and underlying public datasets named in text.
Why Wikimedia images?
Reusable licences and stable Wikipedia titles feed our media pipeline.
Do maps show race?
No. They show languages, density, migration or methods — never race league tables.
What about disputed borders?
Cultural pages note conflict when relevant; atlas layers prefer demographic basins over propaganda maps.
Is genetic distance racist?
The metric is not; using it to rank human worth is.
Where should I start reading?
Pair this page with Race is not biology in the diversity pillar.
