Document Summary
Domestication: involves genetic alteration of plants brought about by human activities. Independently developed in multiple locations (no single cradle of agriculture) Abundant remains of plants that are known to have been cultivated or of tools used for preparing soil, cultivating, or harvesting. Looking at human skeletons as they can provide us with ratio of isotopes that can be compared to skeletons that did not eat cultivated foods. Amount of wear on the teeth of archaeological skeletons. Fossilized plant material that differ signi cantly from wild plants in nearby areas. Nding plant remains that show morphological characters of domestication. Changes in plant characters such as seed size or fruit morphology. Pollen grains because they have characteristic sculpting that allows botanists to determine the species or genus from which they came from. Phytoliths: silica particles found inside the cells of many plants.
