Have you ever wondered what makes humans different from other animals? What makes us different from even our closest living relatives, chimps and other primates? Approximately 7 million years ago, the human and chimp lineages diverged from a common ancestor. What environments, behaviors, and selective pressures contributed to the distinct evolutionary history that produced our species? There are many factors, but one key aspect of our evolutionary trajectory was the acquisition of animal products and incorporation of meat and marrow into our diet. Initially, this was done via scavenging, which involved both anatomical and behavioral adaptations. In particular, the production and use of stone tools was a major factor shaping the evolution of the human hand. In this episode we talk about the human hand and how it is different from other primate hands. A few key differences that are discussed are:
As a reminder of how important our thumbs are, Bone Lab Radio had the opportunity to attend a summer music education program called “Somerville String Fest”. We decided to go straight into the community and talk to people who know how critical it is to have a strong thumb. To hear the interview and recorded music segments please tune in to our podcast. . The Somerville String Fest is open to violin, viola, cello and bass students age 7+ from and adults from Somerville and surrounding communities. Beginners are welcome! Students with a year or more of experience will be placed in orchestra according to their ability. The string program offers daily orchestra rehearsals, chorus, chamber music, and music theory. Classes include technique and improvisation. Somerville String Fest is a great opportunity for string students to refine their playing abilities over the summer.
