@ Louis Leakey is remembered for his contribution to anthropology, but he was also a linguist, an authority on the Kikuyu tribe of Kenya and hand- writing expert. His contribution to Kenyan and to world culture was unique # Leakey was born into a missionary family who settled in Kenya during British rule. He grew up with black children, and so spoke Kikuyu better than he did English. After he graduated from an English university he went back to Kenya to begin his lifelong study of pre-history # In the nineteenth century Charles Darwin had argued that humans were descended from apes. Since then, scientists have wanted to find evidence to prove who our ancestors are and, as far as is possible after so many thousands of years, how they lived their lives # In the Twenties anthropology had been astonished by the discoveries of Raymond Dart. Digging in South Africa, Dart uncovered fossils which seemed to confirm an early evolutionary relationship between apes and human beings # Leakey worked in East Africa for over 40 years. He made several discoveries which confirmed Dart's findings, but he went further than Dart. Leakey argued that a number of man-like species had existed along- side each other, but only one sur- vived to become the human race # Leakey's findings did not go unchallenged by other anthropo- logists - in particular, many found it hard to agree that more than one species of early human once walked our planet. Today, anthropologists accept at least one other man-like species coexisted with our ancestors # In 1967 Leakey claimed that apes and humans, while they have common ancestry, took separate paths millions of years earlier than anyone previously thought. Leakey's research also confirmed - as Charles Darwin had suggested - that East Africa was the cradle of human civilisation @
