Carina Hoorn on the Evolution of the Amazon Basin

The Amazon Basin is the most biodiverse region on Earth, being the home of one in five of all bird species, one in five of all fish species, and over 40,000 plant species.  In the podcast Carina Hoorn explains how the rise of the Andes and marine incursions drove an increase in biodiversity in the Early Miocene. This involved the arrival of fresh river-borne sediments from the eroding mountains and the diversification of aqueous environments caused by influxes of salt water during the marine incursions. Hoorn is an Associate Professor in the Institute for Biodiversity and Ecosystem Dynamics at the University of Amsterdam and Research Associate at the Negaunee Integrative Research Center, Earth Science Section, Field Museum of Natural History, Chicago.
