There were no migrations in the Middle ages except towards empty steppes. #genetics #scholarshipwithoutBSishardIknow
2- Even places that underwent yuuuuuge ethnocultural changes such as Turkey show little gene flow. Turkey has tiny Turkic genes.

Historians are clueless about migrations.
3- Tiny rates of migration such as .5% per century can lead to big cumulative effects such as Subsaharan gene flow into Egypt ...
4- Historians, anecdote-gatherers, and other entertainers are way behind; genetic evidence is like paternity tests. The last 5 years brought a yuuuge overhaul of beliefs.

5- What the globalist idiots don't realize is that migration is as counterintuitive as compound interest. Had we had a migration rate similar to what we have today over 5-10 C, there would be no differenciation between populations.

Very similar to entropy.
6- This argument explains why historians talking about migration rates in the middle ages > .00005 are wrong (that is close to zero; today's rates are yuuuge by comparison). A tiny rate of migration multiplies...
7- The above thread shows why journos are BS vendors, even with a PhD.

8- Pple forget that history is thousands of years and give you salient anecdotes that effectively dilute when seen locally (as per year or lifetime)

Always funny to see pple like @AdamRutherford lecture people on pseudoscience then miss elementary things from high school math.
