Episode 102 - Parasites
Saturday Dec 12, 2020
Saturday Dec 12, 2020
The word parasite doesn’t typically invoke a lot of happy thoughts for us humans, but as far as life on Earth is concerned, parasitism is a path to success. As we discuss in this episode, an incredible diversity of organisms, past and present, have developed an equally incredible diversity of strategies for stealing, siphoning, and exploiting resources from other organisms.
In the news: surprise bird beak, alligator tails, flightless birds, and chemical re-assessment.
