Question

What is microevolution compared to macroevolution?

Answer 1

Microevolution happens on a small scale, while macroevolution happens on a scale that transcends the boundaries of a single species.

Explanation:

Microevolution happens within a population; it may involve change in allele frequencies due to selection pressure. Macroevolution happens on a scale that transcends the boundaries of a single species, but it must be remembered that small microevolutionary changes add up to appear as macroevolution.

Despite their differences, evolution at both of these levels relies on the same, established mechanisms of evolution such as mutation.
