Lucy, Ardi, Frodo, and us: what old bones and new genetics are revealing today. Who are these people and can we call them family? Listen to Greg Laden and Lynn Fellman discuss how recent fossil and tool discoveries are changing the shape of our family tree. A report earlier this week showed evidence for stone tool use at 3.39 million years ago - much earlier than previously thought. In addition to ancient bones and tools, genetics is filling some of the pre-historic knowledge gaps. For instance, genetic material from 40,000 year old bones show that some of us are one to four percent Neanderthal. As a biological anthropologist, Greg Laden has insight into how the recent finds are challenging intrenched ideas. He'll talk about what new trends are changing our understanding of human evolution. Taking us through past and recent discoveries, Greg's engaging way of thinking critically about the mixing of bones and genes reveal a remarkable and controversial family story.
