Misconceptions about evolutionary theory and processes. MISCONCEPTION: Evolution is a theory about the origin of life. CORRECTION: Evolutionary theory does encompass ideas and evidence regarding life’s origins (e.g., whether or not it happened near a deep-sea vent, which organic molecules came first, etc.), but this is not the central focus of evolutionary theory.

Does evolution fashion perfect organisms? The answer to this question, in a word, is no. There are at least four reasons why natural selection cannot breed perfection. Organisms are locked into historical constraints. As we saw in Chapter 20, each species has a legacy of descent with modification from a long line of ancestral forms.

It’s easy to identify what aging is, but rather difficult to explain why it happens. Professor Michael R. Rose The prevailing theory is that aging is a product of evolution. and what happens.

This is how evolution works—it’s not like X-Men or Pokemon, where an individual can evolve in their own lifetime. Evolution acts on the population, not the person. I think this is the greatest tragedy.

4. Why doesn’t natural selection produce perfectly adapted organisms? Natural selection does not produce perfectly adapted organisms because each population’s evolution is constrained by its existing gene pool, which limits the possible allele combinations and may not contain every allele necessary to confront every challenge. Chance events may also wipe out adaptive allele combinations.
