Homo erectus lived from an estimated 2,000,000 down to 100,000 years
ago. Java and Peking man are included among Homo erectus.
Locations: Europe, India, China, Southeastern Asia, and Africa.
Height: 5 feet 2 inches to 6 feet; Weight: 100 to 150 pounds. Fossils:
Jaws, teeth, and an occasional skull cap and thighbone have been
uncovered. In 1984, a well-preserved almost complete erectus was
discovered in Kenya. Remarkably similar erectus bones and tools have
surfaced in Africa, Asia, and Europe.
Brain Capacity: Donald Johanson says 850 cubic centimeters to 900 c.c.
Richard Leakey claims 900 c.c. to 1100 c.c.. compared to 350 - 400
c.c. for australopithecines, 650 c.c. for Homo habilis and 1400 c.c
for humans. It is thought that erectus' brain weighed around seven
ounces at birth. It would mature at thirty-two ounces compared to
forty-five ounces for an adult human.
Johanson describes Homo erectus as "tall, thin, and barrel-chested."
Their weight and height would place them in the top 17 percent of
modern human males. Based on reconstructed skeleton of a twelve-year-
old male, Johanson believes erectus had a body shaped like many
African groups today. But there were differences....
