2 laws about genetics.
>New distinct genetic profiles form *only* because of inbred populations. What I mean by inbred is a small clan/region that only mix with each other for many generations maybe 1,000s of years. There will never be an American genetic profile because there are no breeding populations.
>Every generation is about 30 years.
The modern European are a mixture of many differnt Upper Paleolithic inbred populations. Two admixture events that occurred 8,000-4,000 years ago between distinct populations who were a mixture of earlier inbred populations defines most genetic diversity in Europe.
The two admixture events I'm speaking of are.
>Between Near Eastern immigrants and native "WHG" 8,000-5,000 years ago.
>Between East European immigrants and the new natives(Near Eastern+WHG) between 4800 and 4,000 years ago.
Each admixture event technically lasted for over a 1,000 years, although most admixture occurred in relatively short time periods. The last one was especially short, but mostly only applies to North Europe, most of it probably occurred for only a few hundred years.
I thought it'd be interesting to get a basic idea how many of our ancestors were apart of biracial couples during those short admixture events. Also, how many common ancestors differnt ethnic groups have during differnt time periods.
If you combine the "2 laws about genetics" with some guesses about all Pre-Historic society you can get some answers to those questions.
Here are those those guess you can combine with the "2 laws about genetics".
>Clan size varied from a few hundred to a few thousand.
>Nuclear families usually had 3+ kids. Polygamy makes things complicated though.
>People usually mated with non-relatives from their clan or near by clans. Extended family unites varied from 30 to 100 people.
Before the Ice age most European's ancestors probably lived in only a few very inbred regions. Nothing resembling modern regional genetic diversity had formed. The "WHG", "Basal Eurasian", "ANE" ancestry in modern Europeans probably comes from the exact same ancestors and exact same regions.
In the first admixture event, Near Eastern+WHG. There's a low chance most Europeans have any significant shared ancestry within Europe. WHG and EEF mixed with each other multiple times in differnt regions. One wave of EEF went via the Mediterranean sea and one via land. There wasn't an inbred populations that all Europeans share lots of ancestry from.
The second admixture event though occurred in a shorter time period and in a single region: East-Central Europe. Ukraine, Hungary, Poland, Germany were probably the primary locations admixture occurred. Then hybrid populations expanded into most of Europe and eventually as far east as India. There's a higher chance that EUropeans share lots hyprid ancestors in from this time period.
