Insect homology and diversity attributed to mutations

Genetic code

Ancient homology underlies adaptive mimetic diversity across butterflies Excerpt: “Surprisingly, our results suggest that modulation of this conserved developmental gene has occurred in tandem between these two deeply divergent butterfly lineages, implying an unexpected and remarkable level of predictability in…

Nutrient-dependent pheromone-controlled stickleback evolution

translocated chromosome

Sexual imprinting on ecologically divergent traits leads to sexual isolation in sticklebacks Excerpt: “Odour differences may be owing to pleiotropic effects of adaptive differences in diet [18], habitat [12] and major histocompatibility complex (MHC) alleles selected by parasite differences [19,20].”…
