Microevolution
Evolutionary changes within a species or small group of organisms, particularly over a short period.
Genetic Changes
Alterations in the DNA sequence of an organism, which can affect its characteristics or behavior.
Population
The total number of individuals or organisms residing within a particular area or habitat.

Final Answer :
A
Explanation :
Microevolution refers to the small genetic changes that occur within a population or species over a relatively short period of time, such as through natural selection, genetic drift, or gene flow. This can lead to the development of new traits or the differentiation of populations within a species. Coevolution, on the other hand, refers to the reciprocal evolutionary changes that occur between two or more species that interact closely with each other, while macroevolution refers to larger scale evolutionary changes that can result in the formation of new species, genera, or higher taxonomic groups. Convergent evolution refers to the independent evolution of similar traits in distantly related species due to similar selective pressures or environmental factors.
