Episode summary introduction: “How old is the Earth?” Generations of scholars have asked this fundamental question, and estimates ranged from a few thousand years to indefinite time spans. Geologic and biologic observations from the 18th and 19th centuries (like Darwin’s theory of evolution and Hutton’s concept of deep time) suggested that Earth was old – but […]
Episode summary: This episode of GEOY takes you back to the 18th century when James Hutton set out for his famous expedition to Siccar Point, and introduced the concept of geological time.

This episode of GEOY is dedicated to brilliant interdisciplinary scientist, and pioneer polar explorer Alfred Wegener, whose theory of continental drift shook the foundations of geology, paleontology, and biology research. While today continental drift and plate tectonics are firmly established concepts, when first proposed Alfred Wegener’s theory was ridiculed and received immense push-back by the scientific community. In this episode geology researchers Janne Liebmann and Bryant Ware take you on a science odyssey from initial rejection of Wegener’s ideas as a “geo fairy tale” to the accumulation of evidence that finally prompted its acceptance and laid the groundwork for the theory of plate tectonics.
