Concept:Darwin's natural selection theory does not support the inheritance of acquired characteristics; this idea belongs to Lamarck.
Explanation:Darwin stated that variations appear naturally in a population.
He also explained that heritable variations are transmitted to offspring.
The "fittest" individuals contribute more offspring to the next generation.
However, Darwin never proposed that characteristics acquired through use or disuse are passed on to offspring.
That idea is Lamarck's theory, not Darwin's natural selection.
So the statement that is not part of Darwin's theory is option A.
Answer:Option A: Characteristics acquired through use or disuse are transmitted to offspring.
