[QUOTE]Originally posted by DD'eDeN: [QB] Lucy (fell from the) Sky? https://anthropology.net/2016/09/06/did-lucy-fall-from-a-tree-and-die/ Four decades after the discovery of Lucy, her remains are quite possibly the most famous discovery in paleoanthropology and one of the more important. The impact of finding a nearly entire skeleton from a 3.2 million year old hominid revealed a lot about human evolution. We’ve learned a lot from Lucy, from biophysics to the geological environment she lived in. Up until recently, however, her cause of death was unknown to us, until now.

Credit Marsha Miller/University of Texas at Austin Almost 10 years ago, Lucy went on tour. While at the University of Texas at Austin, a team put her through a CT scanner and conducted a sort of forensic and paleontologic experiment. Their findings were published in Nature, last week. The team discovered she sustained a compressive fracture, which was confirmed by consulting multiple orthopedists. Lead author, Kappelman, looked at the remainder of the skeleton and found more compressive fractures along with greenstick fractures. The scientists concluded that she came down feet-first and then tumbled forward, holding out her hands in a futile hope of protecting herself. The fractures to her rib cage suggest crushing injuries to her internal organs that would have killed her. Dr. Kappelman and his colleagues hypothesize that Lucy must have fallen from a tree because geologists have determined about the environment where she lived, at the time, was a low-lying wooded area around a stream, with no cliffs nearby. While this is certainly a plausible scenario, many paleoanthropologists are skpetical. - - - Forensic opinion on 'Lucy bad fall'. Nature magazine should not be content with a "plausible scenario for the demise of Lucy", as said by paleoanthropologist William Jungers of the State University of New York at Stony Brook, who reviewed the paper for Nature. Normal fossilization processes can specifically result in this "about mandible ten fragments". The fact certainly indicates a very severe blow to the symphysis. This is the only possible conclusion and, when it comes to topics fossilized, likelihood is that fractures are the result of fossilization. https://www.academia.edu/657066/Dental_Microwear_And_Mechanisms_In_Early_Ho minids_From_Laetoli_And_Hadar  [/QB][/QUOTE]
