Check out the fascinating science behind the evolution of the turtle shell, over 260 million years in the making. --Modern turtle shells are almost as diverse as the turtles themselves. Sea turtles have flatter, lighter shells for gliding through the water. Land-dwelling tortoises have domed shells that can slip free of predators jaws. Leatherback turtles have shells without the ring of bone around the edge. So how did the shell evolve? Judy Cebra-Thomas explores the ancestry of the turtle.Lesson by Judy Cebra-Thomas, directed by Cabong Studios.Sign up for our newsletter: http://bit.ly/TEDEdNewsletterSupport us on Patreon: http://bit.ly/TEDEdPatreonFollow us on Facebook: http://bit.ly/TEDEdFacebookFind us on Twitter: http://bit.ly/TEDEdTwitterPeep us on Instagram: http://bit.ly/TEDEdInstagramView full lesson: https://ed.ted.com/lessons/how-turtle-shells-evolved-twice-judy-cebra-thomasThank you so much to our patrons for your support!
