From the options provided, the correct statements about natural selection and evolution are:
1. Natural selection is dependent upon the current environmental conditions.
2. Evolution occurs over multiple generations.
3. Evolution occurs in a population, not an individual.
Explanation:
1. Natural selection is a process where organisms that are better adapted to their environment tend to survive and reproduce more successfully than those that are less adapted. The adaptation is essential for the survival and reproduction of organisms within their specific environment.
2. Evolution is a gradual change in a species over time. It occurs through the process of natural selection acting on heritable traits that affect an organism's ability to survive and reproduce. This process happens over multiple generations, as individual organisms do not evolve within their lifetimes.
3. Evolution is a population-level phenomenon, meaning that changes in the genetic makeup of a population occur over time. While individuals within a population may exhibit variations, it is the collective genetic changes in a population that drive evolutionary processes.
By understanding these concepts, you can appreciate the intricate relationship between natural selection and evolution in shaping the diversity of life on Earth.
