Which statements about microevolution and macroevolution is true

The options are missing from the question.

The options are;

1) Microevolution can lead to macroevolution.

2) Macroevolution can lead to microevolution.

3) Genetic drift cannot affect microevolution.

4) Natural selection only acts on macroevolution.

The correct answer to the question is option 1

MICROEVOLUTION CAN LEAD TO MACROEVOLUTION.

Explanation:

When we talk about microevolution,we are talking about the formation of species via the process of speciation. This formation of species via speciation is made possible by natural selection,a process whereby organisms that are better adapted to their own environment survive in their environment as well as bring about) reproduce new one/species that are similar to themselves. In this process, changes occur with traits but they do so with time. On the other hand, when we talk about macroevolution,we are referring to when major group of organisms form from those groups of species of organisms that are different in a distinct way/manner.

In macroevolution large number of changes occur in the characteristics of the living organisms present,for example, the evolution of entirely new species from the ones that are previously existing. Therefore,we would say that macroevolution is the result of many microevolution processes.

A good example of this is the development of mammals from non-mammalian species or evolution of whales from terrestrial mammals.
