Lucy Long Ago: Uncovering the Mystery of Where We Came From
Starred Review. Grade 5-10–The Beatles song Lucy in the Sky with Diamonds was playing the night paleoanthropologist Donald Johnson found the first fossilized remains of the hominid that became known around the world as Lucy. This extraordinary discovery changed how scientists understood one of the basic concepts of human evolution–it proved that our ancestors began walking upright before the size of their brains increased. Thimmesh uses this discovery to explore several topics in the fields of anthropology and evolutional biology, such as how the bones were fossilized, the process for deciding that Lucy belonged to a previously unknown species (Australopithecus afarensis), and the cast-making process that allowed biological anthropologist Owen Lovejoy to reconstruct her pelvis and prove that she was bipedal. The author even touches upon what fossils can't teach us about our ancestors–their emotions and family patterns. The final chapter discusses the process used by paleoartist John Gurche to create a life-size sculpture of Lucy. The book's greatest strength is how it underscores the fluidity of our understanding in a field like anthropology; it shows how one discovery can change the thinking of scientists in a dramatic way. This book also emphasizes the rigor of the sciences that study our human ancestors and explains clearly how these scientists carefully take the known to formulate new ideas about the unknown parts of our human history. The clear writing, excellent photographs, and the unique approach of exploring the field of anthropology through one spectacular specimen make this book a first purchase.–Caroline Tesauro, Radford Public Library, VACopyright © Reed Business Information, a division of Reed Elsevier Inc.
