Genetic bottlenecks are touted as the means by which accelerated evolution has occurred in any number of species.
Evolution relies upon severe inbreeding, not just once but many times. It’s not a point of differentiation with Creationism at all.
Nothing is as severe as having only a single mating pair to generate all the genetic material for effectively 6 billion progeny, for a complex species.
Can you cite such a drastic circumstance in any evolutionary bottleneck?
