Question

Quizplus · Accepted Answer

Progressive changes in the fossil record demonstrate descent with modification, which is a key component of evolutionary theory. As organisms evolve over time, they acquire genetic changes that are passed down to their descendants, resulting in a pattern of gradual change over many generations. This pattern is reflected in the fossil record, which shows how different groups of organisms evolved over time.
