Javier Ortega-Hernández will discuss his approach to answering this question by studying organisms that lived more than half a billion years ago in the Cambrian Period (485–541 million years ago). By focusing on the earliest-known animals—some of the most versatile to ever exist—Ortega-Hernández aims to reconstruct the early evolutionary history of major animal groups and contribute to our understanding of Earth’s biodiversity.
