Answer: Microevolution can lead to macroevolution.
Microevolution refers to the formation of species through the process of speciation. The element responsible for this process is natural selection. In this process changes in the traits occur with time. Macroevolution refers to the development of major group of organisms from groups of species that are distinctly different. For example development of mammals from non-mammalian species or evolution of whales from terrestrial mammals.
Macroevolution refers to the large number of changes that occur in the characteristics of the living organisms, like the evolution of entirely new species from previously existing species. Macroevolution is the result of many microevolution processes.
Therefore, microevolution can lead to macroevolution is the true statement.
