SciShow: Solving the 70 Million Year “Gap” in Flower Evolution

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: More than 90% of the plants on Earth are angiosperms, flowering plants whose seeds are enclosed inside fruit. And they’re everywhere -- but exactly how and when these plants came to be so ubiquitous is one of the most stubborn questions in science! Hosted by: Stefan Chin SciShow has a spinoff podcast!
