How was Lucy reconstructed?
They use casts of the fossils, build up muscles and flesh out of clay, paint them and add hair. The result is a reconstruction of what Lucy might have looked like (Figure 2). Scientists do not know exactly how much hair Lucy had, but she may have had less than a chimpanzee and more than a human.
How complete is Lucy’s skeleton?
about 40 percent
Fast Facts on an Early Human Ancestor. Perhaps the world’s most famous early human ancestor, the 3.2-million-year-old ape “Lucy” was the first Australopithecus afarensis skeleton ever found, though her remains are only about 40 percent complete (photo of Lucy’s bones).
How were Lucy’s Bones Found?
Lucy was found by Donald Johanson and Tom Gray on November 24, 1974, at the site of Hadar in Ethiopia. They had taken a Land Rover out that day to map in another locality. After a long, hot morning of mapping and surveying for fossils, they decided to head back to the vehicle.
What percentage of Lucy’s bones were found?
40 percent
Over the next three weeks the team found several hundred pieces or fragments of bone with no duplication, confirming their original speculation that the pieces were from a single individual; ultimately, it was determined that an amazing 40 percent of a hominin skeleton was recovered at the site.
What is the fossil Lucy?

What does the fossil Lucy tell us about human ancestry?
In 1974, Lucy showed that human ancestors were up and walking around long before the earliest stone tools were made or brains got bigger, and subsequent fossil finds of much earlier bipedal hominids have confirmed that conclusion. Bipedalism, it seems, was the first step towards becoming human.
What does the fossil Lucy tell us about human history?
Is Lucy 40\% complete?
Lucy, nickname for a remarkably complete (40 percent intact) hominin skeleton found by Donald Johanson at Hadar, Eth., on Nov. 24, 1974, and dated to 3.2 million years ago.
Why was finding Lucy so important?
Lucy was one of the first hominin fossils to become a household name. Her skeleton is around 40\% complete – at the time of her discovery, she was by far the most complete early hominin known. As the team found more and more fragments, they began to appreciate that they were uncovering an extraordinary skeleton.
