Orcas exist in every ocean, adapting to different conditions and diets. Genome sequencing has allowed insights into their evolution - and similarity to humansGeneticists have deciphered the brief history of the killer whale: the predator that exists in every ocean but has evolved over the generations to hunt in disciplined packs, and specialise in a range of diets.The lesson is that genetic mutations that may have favoured survival in changing circumstances were then enhanced by natural selection - and by social learning within killer whale family groups.
