In today's Year Nine Museum Project session, we were very lucky to welcome Sarah Lloyd from the Oxford Natural History Museum who had brought a collection of skulls!
As she brought the first one out, she explained that the skulls were all replicas, made from 3-D printing, and asked everyone how that made them feel. She observed that people often feel disappointed when they hear that something is a replica, but there are various reasons why museums might use replicas, such as handling, ethical considerations concerning human remains, and also simply that the museum does not own an item, but would like a copy.
This was the case with the first skull. She explained that it was a human skull - human being defined as a mammal with a large brain which walked on two legs. She revealed that this was a model of the skull of the famous "Lucy".
Lucy was discovered in 1974 by palaeoanthropologist Donald Johanson, who was exploring the Afar region in Ethiopia. Lucy was a type of early human called a "Australopithecus afarensis" and her remains are just under 3.18 million years old.
Sarah asked you to put several skulls of different chronological order. You tended to order them on size, but some of you used other things such as the shape of the jaw or the brow. Sarah explained how a researcher had once tried to work out what the brow was for on an early human skull, so he had made a model of it. He discovered that it wasn't much use in stopping the rain or sun getting in his eyes, but it did make him look a bit threatening. He concluded that it must have had some sort of social function.
