SOI seminar: The genomic history of killer whale ecotypes
click for details
Killer whales rival humans as one of the most widely distributed mammals, being found in all the major oceans, from the Arctic to the Antarctic and at all latitudes in between. This global radiation from an ancestral population appears to have occurred rapidly, in less than 250 KYA. Yet, despite their high dispersal potential, killer whales frequently exhibit fine-scale geographic variation in ecology and morphology, often coupled with social and reproductive isolation, and are thus an emerging model for the study of incipient speciation. The role of geographic context and the processes underlying correlated ecological and genetic divergence are still poorly understood and remain hotly debated. Here, we present a global dataset of whole genome sequences to reconstruct the history of the colonisation of the species’ known range, focusing on the establishment of known ecotypes to better understand this potential early stage of speciation.
