Moth Survival Strategies And A Rodent Thumbnail Mystery
If you’re a moth trying to stay uneaten, there are competing strategies. Some moths rely on camouflage, trying to blend in. Other moths take the opposite approach: They’re bold and bright, with colors that say “don’t eat me, I’m poison.” Biologist Iliana Medina joins Host Flora Lichtman to describe a study that placed some 15,000 origami moths in forests around the world to investigate which strategy might work best. Then, mammologist Anderson Feijó and evolutionary biologist Rafaela Missagia join Flora to dive into another evolutionary conundrum: why so many rodents have thumbnails. Guests: Dr. Iliana Medina Guzman is a Senior Lecturer in the School of BioSciences at the University of Melbourne in Australia.Dr. Anderson Feijó is a mammal curator at the Field Museum in Chicago. Dr. Rafaela Missagia is an assistant professor at the University of São Paulo in Brazil.Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Anthropologists Have A Bone To Pick With New Skull Finding
There’s fresh drama in the field of human origins!

The new study claims that Homo sapiens, and some of our relatives, could have emerged at least half a million years earlier than we thought. But big claims require big evidence.Anthropologist John Hawks joins Host Flora Lichtman to piece together the details.Guest: Dr. John Hawks is an anthropologist and professor at the University of Wisconsin-Madison.Transcripts for each episode are available within 1-3 days at sciencefriday.com.
