Summary

There have been several times in evolutionary history where a land-dwelling group has transitioned to life in the water, but few have done it so successfully as the cetaceans. Not only are modern whales diverse and fascinating, but their ancestors have left behind an incredible fossil record of their transition into the sea. All that and more as we discuss the Evolution of Whales. In the news: the evolution of ant castes, the strange skulls of aye-ayes, really old worms (maybe), and a shark turnover.
