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.
The correct sequence of the following events under the influence of natural selection will be:
The natural selection theory explains how evolution occurs within a population. It should be noted that the environment is in a constant state of change.
Furthermore, the poorly adapted individuals have decreased survivorship while the well-adapted individuals leave more offspring than the poorly adapted individuals.
Lastly, genetic frequencies within the population change.
In conclusion, the sequence is 2, 4, 1, and 3.
