If a drought occurred reducing the amount of available water, some trees, such as those with deep roots that can reach the water table, would be naturally selected over other trees. If the drought continued for an extended period of time, the tree population would likely evolve until most of the trees possessed drought-resistant characteristics.
Which of the following allows natural selection and evolution to occur?
A) All members of the population are phenotypically identical.
B) Using other plant parts instead of roots to absorb water from the ground.
C) Increasing the height of the water table (more water available to all the trees).
D) All members of the population have an identical genetic make-up.
E) There is variation among the trees and competition for resources.
