DANG, Lucy's calves and thighs were more than twice the size of those of modern humans.
The ‘granddaddy’ of all early hominins walked on Earth a lot longer than we thoughtPreviously, paleoanthropologists disagreed on Lucy’s bipedal stance. Some thought she likely waddled around with her back hunched over, not unlike today’s chimpanzees. However, Ashleigh Wiseman, a paleoanthropology research associate at the University of Cambridge, created 3D models of the leg and pelvis muscles of the 3.2 million-year-old.

Her thighs in particular were made up of 74 percent muscle, compared to the average 50 percent split between fat and muscle in our species today.
This shouldn’t be too surprising, however, given the world ancient hominids lived in. To manage life in East Africa 3 million years ago, Lucy and her cousins would’ve had to roam wooded grasslands, while swiftly switching to
