Document Summary
Origins: hunter-gatherers were the first human foragers, this shifted ~10,000 years ago. Cultural progress: assuming that agricultural life is inherently superior to foraging, energy is conserved through human efficiency, a more civilized and settled state is achieved, progression. Environmental change: correlation of agriculture"s origins with end of pleistocene era, terminal pleistocene. Marked era of warm climate change, rise of sea level and extinction of many game species. Population pressure: population growth necessitated shift to agriculture over foraging, advantages. Land crops (esp. seed crops) suffers less overexploitation. Coevolution: mutual evolutionary effects of two interacting species on each other, humans proto-domesticate plants and animals. Wild species that are subjected to the domestication process. (e. g. domestic animals and crops: evidence of pd found in many ancient cultures, and some have carried into today. Coevolution (cont. : over time, artificial pressures cause wild resources to increase yield to humans.
