Say liverwort to some random person on the street and you are going to get some funny looks. Say it to the right person, however, and brace yourself because you are about to enter into a world hundreds of millions of years in the making. Liverworts represent something akin to the earliest stages in terrestrial plant evolution. Despite their diminutive stature, the world of liverworts is endlessly fascinating. For this reason I was very excited to sit down for a conversation with this week's guest. Laura Briscoe is a Research & Collections Assistant at The Field Museum who specializes in liverwort biology and her work focuses on cataloguing and describing liverwort diversity. Her research takes her to a small island off the coast of Chile where liverwort diversity far outnumbers that of vascular plants such as trees. This was one of the most fascinating conversations I have ever had and I really think you are going to enjoy it.
