Homework due dates : due by 5pm in ta"s mailbox (ms 7150) Laboratory assignment due dates : origins of the human footprint on the environment. Modern humans emerged in africa (organized as hunter-gatherer societies) Because their numbers were so small tiny global environmental footprint of these societies. Hallmark of their behavior = systematic exploitation of the local natural environment (ex. exploited shellfish and vegetation) Humans are different from all other animals. Nearly all non-human species specialize in a particular food source and exploit a particular ecological niche (ex. cats caught small rodents) Humans consume an unusually wide variety of plants & animals good at exploiting just about everything. Humans migrated out of africa (map based on mitochondrial dna patterns in contemporary human populations) Hunter-gatherer techniques allowed early humans to colonize an extraordinarily wide variety of environments (ranging from tropical savannah to polar tundra)
