Abstract:
The woolly mammoth inhabited large parts of the Northern Hemisphere for hundreds of thousands of years before finally becoming extinct ca 4,000 years before present. Analyses of ancient mitochondrial DNA from a large number of mammoth remains suggest that changes in climate had marked impact on the mammoth’s distribution and population size, likely due to it’s effect on the habitat availability and through sea level changes. At the onset of the Holocene, rising sea levels resulted in that mammoths became isolated on Wrangel Island. Recent analyses on multiple mammoth genomes has now allowed us to trace the consequences of this isolation on the mammoth’s genetic architecture.
