Chris, one of the hosts, is a lefty. He’s always had to deal with what that means. But, why are 85% of humans right-handed while only a disproportionate few are left-handed? It’s not fair! But, it is evolutionary. On today’s episode we talk about how we know when handedness in humans likely developed and why it was the right side that became dominant. Segment two features an interview for Lana Ruck, an archaeologist that studied handedness for her Master’s research.
