Se hela listan på maize.teacherfriendlyguide.org All of this means that the domestication process involved simple unconscious/conscious selection targeted at specific mutations controlling discrete (single) traits and more complex plant-people-genetic-environmental interactions that often played out during plant ontogeny and involved humans “reconfiguring” (Lauter and Doebley 2002:341) the preexisting pool of variability into new combinations. The rst de nite signs of domesticated plants in the Old W orld appear in a string of Early Pre-Pottery Neolithic B (PPNB) farming villages that developed in south-west Asia (Map 1) by ca. Domestication of Plants in the Old World reviews and synthesises the information on the origins and domestication of cultivated plants in the Old World, and subsequently the spread of cultivation Se hela listan på academic.oup.com Domestication is the process of adapting plants and animals to meet human needs. Different regions of the world have worked to domesticate species of plants and animals over many generations The origin of agriculture is one of the defining events of human history. Some 11,000-10,000 years ago bands of hunter-gatherers started to abandon their high-mobility lifestyles in favour of growing crops, and the creation of settled, sedentary communities. Background: The genetic mechanisms underlying the domestication of animals and plants have been of great interest to biologists since Darwin. To date, little is known about the global pattern of gene expression changes during domestication.
The initial phase of domestication represents a selection for increased adaptation to human cultivation, consumption, and utilization. 2019-07-22 · The domestication of plants and animals has been described as one of the most important developments in the history of Homo sapiens. Beginning at the start of the Holocene after the last major glacial period, approximately 12,000 years ago, hunter-gatherer societies began the cultivation of plant species as a major source of food and fiber 1 , 2 , and today we rely on domesticated species for our survival. Se hela listan på dailyhistory.org Continued domestication was gradual, a process of intermittent trial and error, and often resulted in diverging traits and characteristics.
This is from The Variation of Animals And Plants Under Domestication, chapter twelve, 'Inheritance'. Here we find Darwin overflowing with enthusiasm when

As plant domestication increased, so did societies based horticulture cultivation of crops carried out with simple hand tools such as digging sticks or hoes. 26 Areas of Early Plant and Animal Domestication. Domestication took place in such widely scattered areas as Southwest Asia (A1), Central Africa (A2), China (B1), Southeast Asia (B2),
the removal or competing weed species when growing cereal crops). Specifically, we will discuss some of the modern analytical tools that have allowed plant biologists and archaeologists to learn more about crop evolution. We will examine where plant cultivation started and how plants were modified as a consequence of the selection pressures imposed by cultivation leading to their eventual domestication. crop plants compiled across 36 categories, including center of domestication, changes in phenotype and use from the wild to the cultivated forms, uses, exploited organs, and conser-vation status.
Plant domestication fundamentally altered the course of human history. The adaptation of plants to cultivation was vital to the shift from hunter–gatherer to agricultural societies, and it stimulated the rise of cities and modern civilization. The domestication of plants was a signature technology initiated by humans during the transition from hunting–gathering to agriculture, about 12 000 years ago. The initial phase of domestication represents a selection for increased adaptation to human cultivation, consumption, and utilization.

Daniel Zohary, Maria Hopf, and Ehud Weiss. A comprehensive review of the origin and the spread of domesticated plants in southwest Asia, Europe, and North Africa 2018-09-30 · While the topic is not heavily focused on, domestication of animals was just as important as the domestication and farming of plants, because the animals were needed to be able to work the land and were a more reliable source of food than the harvest that may not come. 2018-08-06 · After the harvest, the plant is cut down, and one sucker is allowed to grow up to produce the next crop. Banana Phytoliths The evolution, or plant systematics, of bananas are difficult to study archaeologically, and so the domestication history was unknowable until recently. We studied several key ornamental plant species and conclude that their domestication and breeding, however, is a specific aesthetics-driven dimension of human niche construction that has coevolved with socio-economic changes, new scientific technologies and symbolic-material asset shifts, with a foundation in human sense of beauty and aesthetic values to which ornamental plants appeal. Domestication is a change that happens in wild animals or plants, when they are kept by humans for a long time.

Background: The genetic mechanisms underlying the domestication of animals and plants have been of great interest to biologists since Darwin. To date, little is known about the global pattern of gene expression changes during domestication. Domestication is a process characterized by the occurrence of key mutations in morphological, phenological, or utility genes, which leads to the increased adaptation and use of the plant; however, this process followed by modern plant breeding practices has presumably narrowed the genetic diversity in crop plants. Domesticated plants have long served as excellent models for studying evolution.
