Brittle star fossils provide insights into when, how and why major evolutionary change occurs in Earth history
Present-day biodiversity is the result of millions of years of evolutionary change. Although we can trace back in time most of the major organismal groups using fossils, the very origin of these clades is generally deemed impossible to grasp, hampering our understanding of what drives evolutionary innovations. An international team of paleontologists, including Mats Eriksson and Johan Lindgren, re
