Episode notes
Meteor Triggered Global Collapse
- A giant meteor impact around the Yucatán caused forest fires, acid rain, and a sun-blocking 'nuclear winter'.
- That collapse of ecosystems wiped out large dinosaurs because food and habitats vanished quickly.
Small Generalists Survived Best
- Small, generalist animals that could eat many foods survived the mass extinction better than specialists.
- Traits like small body size, varied diet, and hiding abilities increased survival odds after the impact.
Favor Flexibility To Improve Survival
- Consider ecological flexibility as key to survival in catastrophic change.
- Favoring diverse diets, small size, or refuges like water or underground improves resilience.
