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>
The statement environmental influences begin at birth and continue throughout life is definitely False.
<h3>What do you mean by Environment?</h3>
Anything which is present in the surrounding of an organism is called its environment. The environment is surrounded by abiotic and biotic factors.
Environmental influences will not remain the same throughout life. If a human is affected by a natural disease, it will definitely be cured with medications. Environmental influences sometimes behave as genetic diseases, which stay long or sometimes endless.
Therefore, the statement environmental influences begin at birth and continue throughout life is definitely False.
