I was going to continue with my review of chapter 5 of Evolutionary Genetics: Concepts & Case Studies today, but time does not permit. This section was to focus on the orgination of advantageous mutations from the stochastic cauldron of generation 1 (which, as we've seen exhibits a 1/3 probability of immediate extinction in th subsequent generation assuming Poisson distribution of reproductive variance and fixed population size), so I will point to my older posts on introgression (of advantageous alleles):
The baby model
My fixations
Archaic-modern hybridization
Intogression-1
Introgression in wolves & dogs
Introgression related papers
Bumping uglies with the Neandertal
These will come in handy in the near future because papers are pending which make the general conceptual framework extremely relevant.
