1997. Margaret Poynter. Louis and Mary Leakey helped found the science of paleoanthropology - the study of the earliest ancestors of human beings. The Leakeys' groundbreaking work helped prove that early humans used simple tools and were directly descended from ape-like animals. In 1978, Mary amazed the world with her discovery of fossilized 3-million-year old footprints. These footprints show that early human ancestors walked upright, much the same as modern humans. Richard Leakey, like his parents, became a noted anthropologist and made many important discoveries, including skulls of Homo habilis and Homo erectus. 128 pages, soft cover, b&w photographs. Grades 4-10.
