When did Humans arrive on the scene? • Age of hominids? 7 million years • Age of homo sapiens? 500,000 years • Neanderthals? 140,000-50,000 y.a. • Separate evolutionary line: First genocide? • Cro-Magnon? 40,000 y.a. (fully modern anatomy)
Great Leap Forward When? 50,000 b.p. Emergence of: • Fish hooks, Arrows, Bows, Needles, Engravers, Awls • Art • Jewelry (Beads at first) • Navigation/Boating? (Australia from New Guinea) Proposed Causes: • Voicebox development / language • Brain organization change Lascaux Caves, France
Hunter-Gatherers • Humanity’s only “economic” activity for at least 90% of our existence. • Low population densities (small groups of 40-60; 1 person/ mi2) • Largely egalitarian - every person performs essential functions.
Pleistocene Overkill Hypothesis • Large, slow, or tame animals become extinct shortly after hunter-gatherer arrival in New World, Polynesia, Australia / New Guinea. • Flightless birds, giant cave bear, ground sloth. Giant Extinct Moa, New Zealand Skeleton of Giant Ground Sloth, Los Angeles
Agricultural and Industrial Societies Accelerate Extinctions • Flightless birds, whales, otters • U.S. Passenger Pigeon Mauritius, Indian Ocean Dodo Bird discovered in 1598, extinct by 1681. Dodo Bird, Mauritius, Indian Ocean
Agricultural Revolution Domestication of Plants and Animals • Seed Agriculture - Fertile Crescent, western India, northern China, Ethiopia, southern Mexico (10,000 b.p.) Rice, wheat, and corn account for more than 50% of world population's food calories and were among the first plants domesticated (along with millet, sorghum wheat, rye, barley).
Neolithic Revolution Domestication of Animals • Dog was probably first. • Early domesticated animals: cattle, oxen, pigs, sheep, goats, guinea pigs, llama • role in agricultural production and success • Relationship to success of particular cultures: Indo-European Horsemen
Neolithic Revolution Primary effects: • Urbanization • Social Stratification • Occupational Specialization • Increased population densities Teotihuacan
Human Expansion and Ancient Empires Urbanization and increased efficiency lead to population growth and increased density, which leads to need for more space. Ancient Examples: • Aztecs, Maya • Chinese Warlords / Dynasties • Polynesians • Roman Empire • Muslim / Ottoman Empire Human and environmental costs are inevitable.

Age of European Discovery, Exploration, and Colonization 1492 - 1771: • Bartholomew Dias (Portugal), 1488 - rounds Cape of Good Hope • Columbus, 1492 (Spanish/Italian) - first of four voyages to “New World” • Vasco De Gama (Portugal), 1498 - reaches India • Magellan (Portugal), 1519 - First Circumnavigation • James Cook (England), 1768-1771 - voyages in Pacific / Polynesia; end of era of Discovery The geographical knowledge acquired was crucial to the expansion of European political and economic power in the 16th Century.
Industrial Revolution 1733, First Cotton Mill opens in England 1793, Eli Whitney invents cotton ‘gin 1800, steam engines become common (steamboats, locomotives) 1837, Morse and two Brits, independent of Morse ) invent telegraph 1877, Bell invents telephone 1908, Henry Ford delivers first Model T Geographic Effects?
Global Communications and Transportation Revolution Technology: • Containerization of Cargo (1950s) • Inexpensive International Air Transport (1960s - present) • Internet and earlier Arpanet (1960s) • Personal Computer (1980s) • Satellite Communications (1990s) Geographic Effects?
Today’s Technological Revolution What emerging technologies will change the world? Which parts of the world stand poised to capitalize on them? : • Nanotechnology • Genetic Engineering and Biotechnology • Artificial Intelligence • Robotics and micro-robotics Geographic Effects?

Globalization • The increasing interconnectedness of different parts of the world through common processes of economic, political, and cultural change. The economic, cultural, and environmental effects of globalization are highly contested. Panama, 1997
Transnational Corporations • These companies conduct business in many countries, moving products and capital rapidly across national borders.
