  2. Fossil evidence of Human Evolution 17.3 pp.327-330 Homo erectus…upright man • 1.8 mya – 50,000 ya • Brain 700-1250 cm3 • One skeleton 5’7” tall • Probably first to travel out of Africa: • Found in Africa, China, & Europe What is the genus? Genus = similar group level (can be some interbreeding); first name always capitalized. What is the species? Species = biologically unique organisms; can reproduce fertile offspring; second name always lowercase.
