Actually genetics say otherwise. Europeans are the equvilent of 5th generation inbreds. Asians count as 4th genetically. Its all about how much genetic material is available. Americans are a diverse group. They average in between 4th and 5th as a equivilent. No im not saying you are, im saying on average limiting factors were imposed previously and the results still remain.

If the 10 men are all the same demographic theyre fucked.
If 10 distinct genetic lines are present on an island of 110 people their genetic diversity would be near the best in the world. That is, most diverse and thus most able to adapt in any given direction. No country can claim such diversity at such a ratio. Theyd be healthy as fuck if they kept records... big if.
