Leakey, Louis Seymour Bazett (1903–1972)
Kenyan paleoanthropologist and archeologist. Leakey and his wife Mary (1913–1972),
conducted important research on human evolution. Many of their most important
discoveries were made in Olduvai Gorge, Tanzania. Here, they unearthed (1959)
a hominid fossil Zinjanthropus
or Australopithecus bosei about 1.75 million years old, and found
(1964) the remains of Homo habilis
– thought to be a direct ancestor of Homo sapiens sapiens.
Leakey proposed the "Out of Africa" model of human development. After his
death, Mary and their son, Richard Leakey,
continued to make important finds.
