A team of scientists, led by Natural History Museum postdoctoral researcher Dr. Anne-Claire Fabre, have conducted the first study on how metamorphosis has influenced the evolution of salamanders.

Using micro-CT scanning to study the skulls of this group of animals, the team were able to build a huge dataset of 148 species of and used cutting-edge methods to describe the shape of the with nearly 1000 reference points, known as landmarks.

Dr. Fabre said, “Most studies of this kind are limited to just a few dozen landmarks. Our study is the first large-scale investigation of this incredibly diverse group. We have captured the shape of the skull in such great detail that it has allowed us to learn more than ever before about how these creatures evolved.”
