A distinction can be made between botanical science in a pure sense, as the study of plants themselves, and botany as applied science, which studies the human use of plants. Early natural history divided pure botany into three main streams morphology-classification, anatomy and physiology – that is, external form, internal structure, and ...
Plants are considered domesticated when their life cycle, behavior, or appearance has been significantly altered as a result of being under artificial selection by humans for multiple generations (see the main article on domestication for more information). Thousands of distinct plant species have been domesticated throughout human history.
Human history or world history is the record of humankind from prehistory to the present. Modern humans evolved in Africa around 300,000 years ago and initially lived as hunter-gatherers . They migrated out of Africa during the Last Ice Age and had spread across Earth's continental land except Antarctica by the end of the Ice Age 12,000 years ago.
2-dimensional section of Reeb foliation 3-dimensional model of Reeb foliation. In mathematics (differential geometry), a foliation is an equivalence relation on an n-manifold, the equivalence classes being connected, injectively immersed submanifolds, all of the same dimension p, modeled on the decomposition of the real coordinate space R n into the cosets x + R p of the standardly embedded ...
Plants are also used as feedstock for many industrial products including timber, paper and textiles, as well as a wide range of chemicals. Ornamental plants give millions of people pleasure through gardening, and floriculture is a popular pastime among many. Viticulture and winemaking can provide both culinary and economic values to society.
Beginning in the 1940s, plant pathologists developed breeding programs that were examples of human-induced coevolution. Development of new crop plant varieties that were resistant to some diseases favored rapid evolution in pathogen populations to overcome those plant defenses.
