Human and Turtle Skin: Similar Proteins Evolved From Common Ancestor To Toughen Skin
visa online casino What do humans and turtles have in common? While this may sound like a set-up for a bad joke, researchers from the Medical University of Vienna discovered we have a bit more in common with the reptiles than you might think.

For their study, led by molecular biologist Leopold Eckhart of the University Department of Dermatology at MedUni Vienna, researchers explored the genes responsible for the development of shell skin layers and compared them with the genes of human skin.

It turns out turtles evolved with a hard shell following mutations in a group of genes known as the Epidermal Differentiation Complex (EDC). This genetic variation occurred when turtles split from other reptiles roughly 250 million years ago. Additionally, researchers found the basic organization of the EDC genes found in turtles is similar to those found in humans. This suggests the prototypical EDC genes evolved in a common ancestor of the two species about 310 million years ago.
