Explaining how biodiversity is affected by natural selection

Species with a higher biodiversity (number of differences) will be more likely to survive environmental changes and pass those adaptations onto their offspring.

Explanation:

Natural selection is essentially the "survival of the fittest", so having a variety of organisms with their own adaptations may decrease the chances of them going extinct. If all organisms were the same, there would be very little biodiversity and (almost no) ability to fight change.
