Inbreeding certainly causes problems. The question is when it causes
problems. The book, Geckoes, talks about someone inbreeding pictus to the 13
(not exactly sure, in the ballpark) generation without noting any ill
effects. By selecting the strongest individuals, the colony lasted and may
still be going! An interesting thing about pictus is how females can mate
once and have all the sperm needed to lay eggs for the rest of their lives.
I believe pictus are the food for most of the larger animals where they live.
If a whole pictus population is exterminated, a single female has the means
to correct it and so maybe they have evolved to withstand inbreeding?
just some thoughts,
