Which of the following is not a step in the process of natural selection
Paraphin [41]

Answer:

A step that is not part of natural selection is people select which individuals breed and which ones do not.

Explanation:

Natural selection is a process in which favorable or unfavorable environmental conditions determine the evolution of species, producing differences in their genotype over a long period of time.

As its name indicates, it is a natural selection, in which no intervention by people is contemplated, so that <u>people cannot determine which individuals breed</u>.

Natural selection implies that the characteristics on which the environment influences are inheritable, that there is genetic variability in the population and that the variability of these characteristics implies the ease of reproduction and survival capacity.

<em>The other options do form part of natural selection, since they are based on the three premises of this process: </em>

  • <em>Inheritable characteristics. </em>
  • <em>Genetic variability. </em>
  • <em>The variability of characteristics influences reproduction and survival.</em>
