@Billare yes. that is the (broader) context here: https://twitter.com/AndrewSabisky/status/664445191751880704 … (^_^)@AndrewSabiskyThis Tweet is unavailable. -
@hbdchick@AndrewSabisky If you have a species that is just perfectly adapted to its niche, inbreeding & purging of load can be beneficial -
@hbdchick@AndrewSabisky Fuzzily: In some sense the inbreeding loses the sexual "noise" that prohibits reproducing the adapted phenotype -
@hbdchick@AndrewSabisky But I wouldn't associate that kind of story with humans, who adapt to niches promiscously & need sex's variation -
@Billare not small hunter-gatherer groups, perhaps? some amazonian groups?@AndrewSabisky -
@hbdchick@AndrewSabisky Don't know way-way pre-history. But Gat tells a story that even small hunter-gatherer groups have ways to deal here -
@hbdchick@AndrewSabisky Even though they live at low densities, they consciously cultivate affiliations w/other groups for later exchange - 2 more replies
