Anatomy’s Scott Simpson discusses recent human-ancestor fossil finds

Surprise human-ancestor find—key fossils hidden in lab rock

National Geographic: Last month, researchers found 2 million-year-old human-ancestor fossils trapped in a rock that had been sitting in their lab for years. The findings could resolve unanswered questions. For example, “It’s unclear how the shape of the rib cage evolved in hominins, and also what the relationship of the rib cage shape is to upper limb function,” said anatomy professor Scott Simpson.
