Plant Sciences. Sometimes intercropping (different crops in alternate rows) and relay planting (starting the next crop before the previous one is harvested) are part of the multiple-crops-per-year cycle. Categories: Coupled with hybridization between dissimilar species, introductions of a tremendous number of new forms were generated. . Since the middle of the nineteenth century the population has increased from one billion to six billion, an increase that would not have been possible without increases in agricultural yields. Premium Membership is now 50% off! The transgene can come from a different type of organism, which is possible because all species use the same genetic code to manufacture protein . Recent yield improvement traces back to the rediscovery of Austrian botanist Gregor Mendel's (1822-1884) classic experiments on the heredity of garden peas. . For whatever reason, by 8,000 BC, the die was cast, and humankind had turned towards agriculture. However, fifteen thousand years ago, conditions were quite different. All of the major food crops and domestic farm animals known today were known and used worldwide.

After the cold lifted, the climate rebounded quickly. The work of Charles Darwin and Gregor Mendel in the late nineteenth century, in evolution and genetics, respectively, revealed the biological ." Search through the entire ancient history timeline. And now, there is bioengineering where a gene can come from anywhere in the biological world (genetically modified crops). The agricultural crop list is short. Agriculture started independently in at least three places in the world, each with a distinctive cluster of plants drawn from the local flora: Mesoamerica (Mexico/Guatemala: corn, beans, squash, papaya, tomatoes, chili, peppers), the Fertile Crescent (Middle East from the Nile Valley to the Tigris and Euphrates Rivers: wheat, barley, grapes, apples, figs, melons, lentils, dates), and north China (mid-reaches of the three-thousand-mile-long Yellow River: rice, soybeans, peaches, Chinese cabbages such as bok choy). 1960 – First use with aerial photos in Earth sciences and agriculture.

The PreCeramic Neolithic period saw the gradual intensification of the collecting of wild cereals, and by 8000 BC, fully domesticated versions of einkorn wheat, barley and chickpeas, and sheep, goat, cattle, and pig were in use within the hilly flanks of the Zagros Mountains and spread outward from there over the next thousand years. Agriculture is the raising of domesticated animals and the planting, cultivation, and preservation of crops. see also Agriculture; Agronomist; Grain; Organic Agriculture; Plant Pathogens and Pests.

There are many options for those wishing to study an agriculture-based degree due to the nature of the breadth of the subject. Potatoes were a staple in settlements in the Andes Mountains in South America about four thousand years ago. Once a displaced variety is no longer planted, its genes are lost to future generations unless it is conserved, usually in a seed bank collection or as a heirloom variety. Traditional agriculture selects valuable variants among individual organisms, and breeding is between members of the same or very closely related species. Domesticated animals tend to have developed from species that are social in the wild and that, like plants, could be bred to increase the traits that are advantageous for people. Cite this article Pick a style below, and copy the text for your bibliography. The YD lasted for some 1,200 years, during which time people moved south again or survived as best as they could. But in the 1790s, the horse-drawn cradle and scythe were introduced, the first of several inventions. Agricultural biotechnology began in the 1970s, and people in the United States have been eating genetically modified foods since the mid-1990s. A Timeline of Agricultural Developments. History of Agriculture. Origins of agriculture, the active production of useful plants or animals in ecosystems that have been created by people. Domesticated plants and animals have been (and continue to be) raised at scales ranging from the household to massive commercial operations. For the first time the plant breeding community had a set of principles by which to proceed with the crop improvement process. By eight thousand years ago, farming settlements and villages ringed by crop fields had spread from the Middle East to Eastern Europe.
