C. The selective breeding of animals by humans
D. A sudden adaptation of species to their environment

Answer 1

Evolution is a change in the characteristics of living things over time. It occurs through a process called natural selection, where advantageous traits are passed down to offspring. This leads to major changes in species' characteristics over many generations.

Step-by-step explanation:

Evolution is a change in the characteristics of living things over time. As described by Darwin, evolution occurs by a process called natural selection. In natural selection, some members of a species, being better adapted or suited to their environment, produce more offspring than others, so they pass "advantageous traits" to their offspring.

Over many generations, this can lead to major changes in the characteristics of the species. Evolution explains how living things are changing today and how modern living things have descended from ancient life forms that no longer exist on Earth.

As living things evolve, they generally become better suited for their environment. This is because they evolve adaptations. An adaptation is a trait that helps an organism survive and reproduce in a given environment.
