GuDViN [60]

Answer:

2. A change occurs in the environment.

4. Poorly adapted individuals have decreased survivorship.

1. Well-adapted individuals leave more offspring than do poorly adapted individuals.

3. Genetic frequencies within the population change.

Explanation:

The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.

Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.

Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.

Hence, the sequence of events is 2, 4, 1 and 3.
