In the late Devonian era, the seas began to recede and the land became more fertile. These environmental changes resulted in the
emergence of land-dwelling vertebrates. Some animals are better able to survive and reproduce under changing environmental conditions. This is an example of:A. evolutionB. mutationC. speciationD. natural selectionE. adaptation
<em>Natural selection is an evolutionary process in which organisms that are better adapted to changes in the environment survive and contribute more to the subsequent generations in terms of reproduction.</em>
The weak organisms gradually phase out of the population because they are weakly adapted to changes in the environment. Hence, they are not able to survive and or reproduce.
<u>Hence, processes whereby some animals are better able to survive and reproduce under changing environmental conditions ahead of others are natural selection processes.</u>
