Europe's last hunter-gatherers avoided inbreeding by [[Dario Radley]]
Any evidence of moieties in these groups? How would one test this compared to modern instantiations in indigenous peoples?
-
The genomic analysis also challenges earlier theories that suggested hunter-gatherer communities assimilated women from neighboring farming communities.

mutational meltdown
Mutational meltdown happens in a population of animals if their number is so low that negative mutations and deletions in their DNA accumulate.
-
Minimum viable population is about 500 individuals, with 1000 to prevent negative genetic drift
Rule of thumb: 500 minimum viable population, 1k minimum to prevent negative genetic trends (inbreeding).
Is a similar rule of thumb thinkable for communities of practice in terms of maintaining the community itself, and in terms of keeping it varied / valuable enough on all [[Community building 20100210214508]] aspects Wenger et al list?
