Have you ever wondered how there are so many breeds of dogs in the world. Or, have you wondered why there are so many varieties of fruits and vegetables. It’s all thanks to artificial selection and selective breeding! Akshay visits the animal shelter in search of a new pet, and sees all of these hundreds of breeds to choose from. Curious about selective breeding, Akshay visits Dr. Ian Dworkin, a professor at McMaster University in Canada, in his awesome fruit fly lab to learn more about artificial selection. You’ll see why fruit flies are important to the study of artificial selection and will learn more about this concept in this amazing episode.

Special thanks to Dr. Will Ratcliff for arranging this interview with Dr. Dworkin!
