Did x-rays solve this 3.2-million-year-old mystery?

Lucy, a 3.2-million-year old skeleton of the hominim species Australopithecus afarensis, is among the most famous specimens in anthropology since her discovery in Ethiopia in 1974. Named after the Beatles' "Lucy in the Sky With Diamonds," she still has a bit of a mysterious past. A recent report in Nature Communications details how a team used the High-Resolution X-ray Computed Tomography Facility at Jackson School of Geosciences to scan Lucy for 10 consecutive days.

The research team believes it has found evidence that Lucy died from a fall, perhaps out of a tree, as detailed in Washington Post update. Others, however, call in to question such an assumption, claiming such a conclusion is something which cannot be proven or disproven.
