Interesting. I imagine it's been studied, will have to check the literature. Lol at the idea Japan (e.g.) needs "fresh blood" from outside

Two most obvious downsides of excessive inbreeding: 1. Bad recessive genes more likely to come together and reduce offspring fitness. (can

be solved by weeding these out) 2. Inbred population is more homogeneous, more vulnerable to certain threats. Eg

new disease wipes everyone out. With more diversity, at least some would survive.

However, inbreeding is your friend if you're trying to speed up evolution & direct it towards certain traits.

I do remember hearing that, extrapolating from fruit fly expts, we could dramatically increase lifespan with only selective breeding
