Natural selection. Only spiders that were more resistant to the pesticide lived through the first spraying of the pesticide, thus we're the only ones that could reproduce. This in turn made the offspring of the previous generation more resistant as well; thus making the pesticide less effective.

Finches that live in an isolated area with limited access to seeds and water is an example of what mechanism in Darwin's theory
Brums [2.3K]

Answer:

c. Limits on population growth

Explanation:

Darwin was heavily influenced by Malthusian theory of how population growth was influenced by growth limits. For Darwin, the population growth of species of living beings would be influenced by the limits imposed by the environment in which these species live, through the amounts of natural resources available to the population.

Thus, Darwin concludes that when the environment allowed an abundance of natural resources, such as water and food, the population of living beings would tend to grow more, however, when natural resources are limited, the population would grow less. This is called "population growth limits".

An example of this can be seen in the question above, where finches that live in an isolated area have limited access to seeds and water.
