Along with physical characteristics, scientists also use genetic analysis to classify organisms by comparing DNA sequences of species. Suppose a scientist classifies two newly discovered fossils as being very closely related based on their physical characteristics. What type of genetic evidence would likely cause the scientist to reevaluate the classification of these fossils? Explain your reasoning.
