Answer:
Evolution by artificial selection is a process in which humans selectively breed plants and animals in order to enhance or suppress certain desirable or undesirable traits. This process is commonly used in agriculture to produce food that is larger, tastier, more nutritious, and more resistant to pests or disease.
One example of this process is the evolution of modern corn. Corn is a staple food in many cultures and has been selectively bred by humans for thousands of years. Early farmers would save the seeds of the best crops and plant them again the following year, gradually selecting for plants with larger kernels, more rows, and more uniformity. Over time, this process resulted in the evolution of the modern sweet corn that we eat today.
Similarly, many fruits and vegetables have been selectively bred to enhance their flavor, size, and nutritional content. For example, wild strawberries are small and tart, but selective breeding has produced larger, sweeter, and juicier strawberries that are more appealing to the modern palate.
Artificial selection has also been used to produce food that is resistant to pests and disease. For example, many crops have been genetically modified to produce toxins that repel insects, reducing the need for pesticides. This has resulted in more efficient and cost-effective food production, as well as reduced environmental damage.
In summary, evolution by artificial selection is an important process that has shaped the food we eat. By selectively breeding plants and animals, humans have been able to produce food that is tastier, more nutritious, and more resistant to pests and disease, resulting in more efficient and sustainable food production.
