PRE-HISTORY EVOLUTION OF MAN

HOMO HABILIS 3 to 1 million years ago Larger brain than ape Made simple tools from stone Found in Eastern and South Africa Did not migrate

HOMO ERECTUS 1.6 million years ago Walked more upright, taller Larger brain, wider/longer skull Less prominent jawline Developed more sophisticated tools » Flint » Hand axes » Discovered fire Migrated beyond Africa to Europe, Asia and eastern China

NEANDERTHAL 200,000 BC Shorter and stockier Flat skull with receding forehead and thick brow ridge Specialized tools – Spears – Chisels – Borers Buried their dead with rituals – Skeleton remains encircled by stones, animal horns and flowers, due to evidence of pollen. Resided in communities Confined to Europe and Middle East Died out in 35,000 BC (co-existed with Homo sapiens)

HOMO SAPIENS (WISE MAN) 100,000 BC (current man) Dome-like skull to hold a larger brain Less pronounced eyebrow ridge Evolved variations in height, color and physiognomic features More advanced Developed projectile weapons (ie.. spears) – Could kill from a distance – Decrease injuries Ability to build shelters Hearths to keep fires alive longer Different material for tools Needles from bone Rope and thread from animal and plant fiber

START OF MIGRATION Negroid – Remained in Africa Mongoloid – 60,000 BC – Migrated from Africa to Asia Caucasoid – 40,000 BC – Migrated from Africa to Europe and Western Asia

DATING METHODS

SEQUENCE DATING Studying pottery Each civilization’s pottery was different in design, shape or texture

CARBON-14 All living things absorb a radioactive substance that decays at a known rate every year. The remains of the radioactive substance tells how long it has been dead. Not used to date beyond 1000 BC

POTASSIUM The decay of radioactive minerals in rocks Potassium is a metal-like element found in nature Argon is a gas Only applied to rocks formed by great heat, like volcanic action

TREE RING Used to double check carbon-14 dating Count the rings inside the tree trunk
