Dogs that have a desirable coat color are bred with one another to produce puppies.

Detailed explanation-1: -Natural selection is the process through which organisms with greater environmental adaptations survive and reproduce more. After industrialization, the proportion of dark-winged moths rose, an example of natural selection.
Detailed explanation-2: -This is ‘natural selection’. Consider the giraffe, for example. A Darwinian theory of evolution posits that it was through random variation that some giraffes had longer necks than others. Thanks to their long necks, they were able to reach leaves high up in the trees in their environment.
Detailed explanation-3: -Which of the scenarios is an example of natural selection? During a five-year drought, the proportion of late-blooming plants in a wildflower population decreases. Natural selection favors traits that improve survival and reproductive success.
Detailed explanation-4: -Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
