Discuss the Genetic Changes in the Domestication of Plants in the New

Question

Examlex · Accepted Answer

The Answer is The genetic changes in the domestication of plants in the New and Old Worlds were influenced by different selective factors and resulted in different outcomes. In the New World, plants such as maize, beans, and squash were domesticated, while in the Old World, plants like wheat, barley, and rice were domesticated.

In the New World, the selective factors for domestication were likely related to the need for plants that could thrive in the diverse environments of the Americas. This led to genetic changes that allowed for adaptation to different climates and soil types. In the Old World, the selective factors were likely related to the need for plants that could withstand the challenges of large-scale agriculture and trade.

These differences in selective factors led to different genetic changes in the domesticated plants. For example, in the New World, maize was selected for larger kernels and more efficient harvesting methods, while in the Old World, wheat was selected for traits that made it easier to process and store.

These facts and their role in the history of domestication help explain the differences between natural selection and artificial selection. Natural selection is the process by which organisms with traits that are better suited to their environment are more likely to survive and reproduce, leading to the gradual evolution of a species. In the case of plant domestication, natural selection played a role in the initial adaptation of wild plants to human cultivation.

Artificial selection, on the other hand, is the process by which humans intentionally breed plants or animals for specific traits. This can lead to rapid and dramatic changes in the genetic makeup of a species, as seen in the domestication of plants in both the New and Old Worlds. The different selective factors in each area led to different genetic changes, demonstrating the power of artificial selection in shaping the genetic diversity of domesticated plants.
