Paleoanthropologists classify ancient human fossil remains into different species – but what are fossil species, and how can we recognize, define, and delimitate them? Ryan McRae is a biological anthropologist in the Center for the Advanced Study of Human Paleobiology at the George Washington University and an expert in understanding the patterns of evolution in our lineage. In this presentation he will discuss how early species are defined and what we know about the completeness of the early human fossil record. 

Moderator: Briana Pobiner, paleoanthropologist and educator at Smithsonian’s National Museum of Natural History.

This Zoom webinar with Ryan McRae aired live on March 15, 2022 as part of the ongoing "HOT (Human Origins Today) Topic" series.
