SciShow: Was Johnny Appleseed Wasting His Time?

Teacher or professor: SciShow

Content of the Lesson: If you know anything about apple genetics, you know that Johnny Appleseed had no way of knowing what apples would come from those seeds. But genetic studies suggest he, or people like him, may actually have helped apples maintain their genetic diversity up to the present day. Hosted by: Olivia Gordon SciShow has a spinoff podcast!
