Eons: How the Walrus Got Its Tusks
The rise and fall of ancient walruses, and how modern ones got their tusks, is a story that spans almost 20 million years. While there are parts of the story that scientists are still trying to figure out, it looks like tusks didn’t have anything to do with how or what these animals ate. Part of the "Eons" series. Please note this title contains discussions on sexual reproduction and selection.
