Andrea and Casey dive into their Zoological roots on this episode of ThunkTink! What could make for a more harsh environment than ghosts? And why don’t people go hunting for animal ghosts? What coloration is associated with pride in the animal kingdom? What if we designed an experiment to look at whether fishes took more pride in some of their offspring? Why aren’t there fossil records of mythological creatures in fantasy series? What would be required to facilitate the evolution of fairies? All this and more discussed this time on ThunkTink!
