B: All species descended from a single common ancestor, and evolution is driven primarily by genetic mutations.
C: Life spontaneously generates from non-living matter, and only the strongest individuals survive.
D: Organisms strive for perfection and pass acquired traits to offspring, leading to adaptation.
