Podcast 161 - Whales Not Whales

The gang discusses two papers that look at how various animals associated with whales have reacted to environmental shifts over the last several hundred thousand years. The first paper looks at polar bears and reviews data on the potential utility of whale carcasses on polar bear survival during warmer periods in recent Earth history. The second paper investigates how changes in the shell chemistry of barnacles attached to whales may preserve important information on whale migratory patterns. Meanwhile, James has ideas about Final Fantasy and all Square Enix protagonists, Curt thinks James is the Kuja of the podcast, and Amanda finds her ideal Nobody name. Somehow we got on a real theme this episode.

Up-Goer Five (Amanda Edition):

 Today our friends do not talk about very large big heavy things that had hair once. Instead our friends talk about small weird hard things that don't move that do not look like tiny things with many legs but are actually very close to tiny things with many legs. These things that do not look like tiny things with many legs but are actually very close to the tiny things with many legs are hard and live on the very large big heavy things that had hair once, but do not hurt them. They are friends, but the large big heavy things that had hair once don't actually care about the small weird hard things that don't move. But the small weird hard things that don't move can help us see if the big large heavy things that had hair once move around when it goes from warm to cold or not. It turns out that maybe even very old big large heavy things that had hair once might have moved around just like today's do. Our friends also talk about large white angry things with hair that want food that eat the large big heavy things that had hair once. These large white angry things with hair are in trouble because their home is going away. Their home has gone away in the past, and maybe they ate the big large heavy things that had hair once when they died and came on land. One big large heavy thing that had hair once can be food for lots and lots of large angry white things with hair. But people have killed a lot of the big large heavy things that had hair once, and that might be a problem. Maybe the big white angry things with hair won't be able to eat the large big heavy things that had hair once anymore, and they will all die.
