Mention any two examples of evolution by anthropogenic action.

Explanation

**Step-by-Step Solution:**

1. **Understanding Anthropogenic Action**: Anthropogenic action refers to changes in the environment or evolution that are caused by human activities. This includes artificial selection, where humans selectively breed organisms for specific traits.

2. **Example 1 - Domesticated Animals**: One example of evolution by anthropogenic action is the selective breeding of domesticated animals. For instance, cows have been selectively bred for high milk production. Farmers identify cows with the best milk yield and mate them with selected bulls to produce offspring that also have high milk production traits. Over generations, this has led to the development of breeds that are significantly more productive than their wild ancestors.

3. **Example 2 - Crop Plants**: Another example is the evolution of crop plants through selective breeding. A prime example is the domestication of wild kohlrabi, which has been selectively bred to produce various vegetables such as cabbage, cauliflower, and kohlrabi itself. Through this process, humans have enhanced the traits of these plants to improve yield, taste, and nutritional value.
