| Outline of Final Research Achievements |
Morphological innovations are those evolutionary novelties that appear without a clear ancestral structure, totally de novo. The turtle shell is a classical morphological innovation that has mesmerized researchers over a century, and despite deep studies addressing its origin, how turtles acquire the shell remains a mistery. During my project, I have utilized state-of-the-art technologies in order to tackle this problem. By using techniques of next generation sequencing, like ChIP-seq, I have been able to establish hundreds of candidate regultatory elements that seem to be turtle-specific and linked to the carapacial ridge, the embryonic structure that controls de development of the turtle carapace.
