Genetic connectivity across marginal habitats: the elephants of the Namib Desert - Ecology and Evolution.The importance of intelligent, memetic evolution, as opposed to genetic evolution, is being increasingly recognised especially in sentient species. Groups of sentient animals can appear to be a different species based on lifestyle, habitat, social organisation, etc and yet be genetically almost indistinguishable. Pods of killer whales, for example, may have very different hunting strategies and occupy different parts of the ocean but differ only from other pods by culture.
