Thomas Malthus, a political economist, showed that the human population would outstrip available resources unless kept in check
vredina [299]

Answer:

C. Darwin realized this also applied to plant and animal populations, and this struggle for existence resulted in an opportunity for natural selection to act on differences within populations.

Step-by-step explanation:

Thomas Malthus in his Malthusian theory of population concluded that since population increases geometrically and  resources only increase arithmetically, there will reach a point in time when the resources will be not be able to sufficiently cater for the population.

The Charles Darwin theory of Evolution is based on five key observations and conclusions drawn from them. These observations and inferences are summarized as:

  • Species are more fertile. They birth more offspring than can grow to adulthood.
  • Populations remain fairly stable with miniscule fluctuations.
  • Food resources are limited, but are relatively constant most of the time.

<em>Based off these observations, it is seen that there will be a </em><u><em>struggle</em></u><em> amongst the members of the specie for the </em><u><em>limited resources.</em></u>

  • In sexually reproducing species, generally no two individuals are identical. Variation is rampant.
  • Much of this variation is heritable.

<em>From the last two observations, the species that survive then pass on their traits to their offspring and the cycle repeats itself with each subsequent generation being </em><u><em>better evolved</em></u><em> than the previous ones.</em>

Thus, Darwin discovered that the Malthusian theory of population also applies to plant and animal populations where <u>scarcity of resources</u> gives room for <u>natural selection</u> to take place due to the variation within populations.
