Models of Selection, Isolation, and Gene Flow in Speciation

摘要: Many marine ecologists aspire to use genetic data understand how selection and demographic history shape the evolution of diverging populations as they become reproductively isolated species. I propose combining two types analysis focused on this key early stage speciation process identify selective agents directly responsible for population divergence. Isolation-with-migration (IM) models can be used characterize reproductive isolation between (low gene flow), while codon differences at molecular level (especially positive high rates amino acid substitution). Accessible transcriptome sequencing methods generate large quantities needed both analysis. highlight recent examples (including our work fertilization genes in sea stars) which confluence interest, models, has led taxonomically broad advances understanding spec...
