Which of the following statements is NOT correct ?

The Hardy-Weinberg Principle states that allele frequencies in a population are stable and remain constant from generation to generation, provided there is no evolutionary pressure. This state of genetic stability is called genetic equilibrium. Therefore, statement A is incorrect because it describes the frequencies as "unstable."

• Statement B: Branching descent and natural selection are indeed the two key pillars of Darwin's theory of evolution.
• Statement C: Lamarckism is the hypothesis that an organism can pass on characteristics that it has acquired through use or disuse during its lifetime to its offspring.
• Statement D: The Hardy-Weinberg equilibrium is disturbed by five specific factors: gene migration (or gene flow), genetic drift, mutation, genetic recombination, and natural selection. Any change in the frequency of alleles in a population indicates that evolution is occurring.
