Scientists from the UAB and Iowa State University have generated the genome assemblies of two hidden-neck turtles. The results, which revealed a new three-dimensional structure of the genome within ...

In most vertebrates, skin appendages such as hair, feathers, or scales originate from placodes—small, specialized skin regions whose spatial organization is controlled by well-conserved genetic ...

In vertebrates, the formation of feathers, hair, and scales is typically governed by molecular genetic factors. However, crocodile head scales are an exception, as they form through a purely ...

Learn how a 260-million-year-old Permian reptile, once thought to explain turtle evolution, turned out to belong to a different lineage, reshaping the story of turtle origins in the Triassic Period.
