The secrets in a 240M-year-old tree of life
Squamates are among the most successful species on the planet. They’ve been evolving for 240 million years, including the mosasaurs of the Cretaceous Period and the lizards and snakes that populate Arizona—and the entirety of the planet—today, despite the extreme diversity of environments that exist. Biologist Marc Tollis is leading an NSF-funded project to sequence the complete DNA of 100 species in the Squamate order with the goal of uncovering what genes have contributed to their successful evolution.
