- description: What does a ginkgo tree have in common with a dinosaur? SUBSCRIBE, it's FREE! http://bit.ly/iotbs_sub ↓ More below ↓ Every fall, in cities like New York, the smell of vomit fills the crisp air. The culprit? The pungent seeds of the ginkgo biloba tree. So why would a tree evolve such a disgusting and revolting way to disperse its genes and make baby trees? Why not be more like the delicious apple? Join me for an evolutionary ghost story. We'll find out why the ginkgo is so weird, visit with some prehistoric beasts, and learn how an avocado is a bit like a dodo bird.
