Why can evolution not be explained only on the basis of acquired traits?
Answer and explanation
Correct answer: Because acquired traits usually do not change genetic information in reproductive cells
Evolution across generations depends on heritable changes that can pass from parents to offspring. Acquired traits, such as increased muscle strength from exercise, generally affect body cells and do not alter the genetic information of reproductive cells. Hence they are usually not inherited in that form, making option A correct. The other options incorrectly claim that acquired traits are always inherited, never occur, or are chromosomes.
