CARTA: How Did Lucy Become a Fossil? Investigating the Life, Death, and Preservation of a Famous Hominin with Anna Behrensmeyer

8/23/2024; 21 minutes

Lucy's 1974 discovery reshaped our understanding of early hominins. Geological studies dated her to 3.21 million years ago. Questions arose about her life and death, leading to investigations into her burial site and skeletal preservation. Found scattered on the surface, less than 40% of her skeleton was preserved. Some parts were articulated, indicating rapid burial, possibly by a river. Missing elements suggest scavenging and erosion. Debate surrounds her cause of death, with theories including a fall or predation. Bone fractures hint at trauma, but the exact circumstances remain unclear. Geological evidence disputes death by mudslide or flood. Tooth marks on her bones lack conclusive evidence of predation. These debates underline Lucy's enduring influence on paleoanthropology, sparking ongoing research into human evolution. Recorded on 04/06/2024. (#39823)
