Paleontology is more than just the study of old bones; it is a high-stakes forensic investigation into how life adapts or fails to adapt when the world changes. In this talk, we move beyond basic fossils to explore biological history through time. We will examine how evolutionary paths are paved by both survival and sudden collapse, uncovering how the genetic signatures of extinct species continue to shape the biological reality we inhabit today. Join me for a look at the dark side of evolution and how humanity can learn from the survival strategies of creatures from the earths past.
