#457 Trowel Blazing
This week we look at some of the lesser known historical figures and current public perception of anthropology, archaeology, and other fields that end in "ology". Rebecca Wragg Sykes, an archaeologist, writer, and co-founder of the TrowelBlazers, tells us about the Raising Horizons project and how their team is trying to shine the spotlight on the forgotten historical women of archaeological, geological, and palaeontological science. And Kristina Killgrove, assistant professor of anthropology at the University of West Florida and science writer, talks about the public perception of the fields of anthropology and archeology, and how those science are represented -...
