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. 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.

Station in Ames, Iowa. Sunflower is one of only a few important crops domesticated from germplasm native to North American.

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.

To successfully feed a society using plants, the first humans had to continually work to improve their yield in quality and quantity. The domestication of the plant was man’s crowning achievement. It allowed us to develop into the complex global society that we are today.

Thousands of distinct plant species have been domesticated throughout human history. 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.

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.

The aim was to preserve wild plants and animals from commercial overexploitation.
