Brother-sister unions (think pharoah) could be considered mere extreme consanguinity (all grandparents shared, vs one set of shared grandparents). Consanguinity is considered permissible in many cultures, including most western societies. The genetic disadvantages are presumably outweighed by the stable environment (=property) rights conserved in a family. Consanguinous unions are much studied, and are not so bad as all that, providing there are no pre-existing genetic conditions in the lineage. Incest taboos among humans in the Pacific are interestingly different, though my knowledge of this is exceedingly slim. <br />As for the animal kingdom, It is a curious fact that all thoroughbred horses in England are descended from only three stallions imported from Arabia in the 18th century. The horse racing scene seems healthy enough.<br />So though personally I'm a believer in the value of hybrid vigour, I think we should acknowledge the ideological nature of this discussion, and I'd be more optimistic about the outcome of the last man/last woman scenario than you. I guess it would depend on which man and which woman. Obviously that's a much chancier situation that starting off from a population of 7 billion...Douglas Carnall, @juliuzbeezerhttps://www.blogger.com/profile/13563159368217318352noreply@blogger.comtag:blogger.com,1999:blog-404048195677170545.post-76984873316107085692015-03-12T21:40:29.542-04:002015-03-12T21:40:29.542-04:00This an interesting concept.

Who knows what kind of interesting populations might come from the process, and what positive and negative evolutionary traits might arise throughout the generations. Still, survival of the fittest has to have contributed extensively to the humans of today, and we are not perfect. Good enough to reproduce and get our offspring to reproduction age and so on. Maybe in the end, the rest is self-correcting?Chandler L. Walker, Ph.D.https://www.blogger.com/profile/05286452268298448852noreply@blogger.com
