Answer: Increased reproductive success of individuals with the ability to survive in a variety of water temperatures

Explanation: Natural selection establishes that the conditions of an environment favor or hinder (select) the reproduction of organisms according to their characteristics. Natural selection was proposed by Darwin as a means to explain biological evolution.

The trait subject to selection must be inheritable.

There must be variability of the trait among the individuals of a population.

The variability of the trait must give rise to differences in the survival or success of the player, making certain characteristics of the new appearance can be extended in the population.

The accumulation of these changes over generations would produce all evolutionary phenomena.
