<u>Option- A:</u> Is the best option to choose from the given four, as we have the explanation given as below;
<u>Charles Darwin: </u>He was a British naturalist who proposed the theory of biological evolution by natural selection.The mechanism that Darwin proposed for evolution is natural selection.
Explanation:
<u>Darwin’s process of natural selection has four components:</u>
<u>Variation:</u> Organisms (within populations) exhibit individual variation in appearance and behavior.
<u>Inheritance:</u>Some traits are consistently passed on from parent to offspring.
<u>High rate of population growth:</u>Most populations have more offspring each year than local resources can support leading to a struggle for resources.
<u>Differential survival and reproduction: </u>Individuals possessing traits well suited for the struggle for local resources will contribute more offspring to the next generation.
Answer: Multiple types of evidence support the theory of evolution: Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features).
