The process by which wild plants and animals are genetically modified over time by humans for their benefit is a fundamental concept in AP Human Geography. This selective breeding results in organisms that are more suited to human needs and environments, often exhibiting traits that would be disadvantageous in a natural setting. A prime example is the cultivation of teosinte into modern corn, or the taming of wolves into domestic dogs.
Understanding this concept is crucial because it underpins the development of agriculture, sedentary lifestyles, and ultimately, the rise of civilizations. The ability to control and manipulate food sources provided a stable surplus, allowing for specialization of labor, population growth, and the emergence of complex social structures. Furthermore, the spread of domesticated species, along with agricultural practices, significantly impacted global landscapes and biodiversity.
