What Bones Reveal: Fossils, Human Evolution, and the Technology of Discovery
Ava Nederlander hosts a Halloween episode that looks past ghost stories to what skeletons can tell us about life, movement, and evolutionary history. She speaks with Dr. Gabrielle A. Russo, Associate Professor of Anthropology at Stony Brook University and Interim Director of the Turkana Basin Institute. They talk about how a single bone can record whether a primate climbed, swung through trees, or walked upright, including the loss of the tail in apes and the shift toward bipedalism, and about searching for fossils at Napudet in Kenya. The second half turns to the technology of discovery: high-resolution CT imaging, three-dimensional digital models, and how researchers compare ancient bones with living primates when a fossil is incomplete. They also discuss enamel proteomics, an emerging way to recover evolutionary information from proteins preserved in tooth enamel long after DNA has degraded. The full recording will also be available on YouTube.
