A subpopulation of sociopaths is GTO for social organisms, but a subpopulation of autists might be GTO for a social culture @DoTheWeirdStuff
@St_Rev we were just talking about variability - why do you think predictability determines this? (cool insight)

@sarahdoingthing ...to arise in the fast-mutating pop. OTOH if the organism is already well-adapted, the 2% tax dominates. -
@St_Rev YES YES YES this is a great structure - 4 more replies

@sarahdoingthing But if you have one population that mutates once in 1000 generations & another that mutates one in 50 generations... -
@St_Rev god dammit I hadn't even thought about mutation rate being itself variable (and perhaps selected fuck)

@sarahdoingthing ...then the fast-mutating pop generates 20 times as many positive mutations as the slow-mutating pop.Thanks. Twitter will use this to make your timeline better. UndoUndo

@sarahdoingthing Mutation rate imposes a small fixed cost--if you mutate once in 50 generations, that's effectively a 2% tax on reproductionThanks. Twitter will use this to make your timeline better. UndoUndo

@sarahdoingthing Now IF the pop is experiencing high selection pressure--it's far from an optimum--then adaptation is 20x more likely...Thanks. Twitter will use this to make your timeline better. UndoUndo

@sarahdoingthing There was a pretty simple mathematical explanation of selection for mutation rate in the paper. Basically...Thanks. Twitter will use this to make your timeline better. UndoUndo
