It is apple picking season here in New England. Take a stroll through a local orchard and you’re likely to see a bunch of different types of apples. In fact, you might even find a type of apple that you haven’t previously seen. The reason for this is explained in a new TED-Ed lesson titled Why Are There So Many Types of Apples?

In the lesson students can learn how new types of apples are developed, the benefits of developing new types of apples, and how many types of apples currently exist in the world.
