Final answer:
Scientists can use morphologic and genetic evidence to classify cheetahs and leopards in different genera.
Step-by-step explanation:
Scientists can use two types of evidence to classify cheetahs and leopards in different genera: morphologic (form and function) and genetic. Morphologic evidence involves comparing physical features, such as the shape and size of bones, to determine similarities and differences. Genetic evidence involves studying the DNA of cheetahs and leopards to identify similarities and differences at the molecular level. By combining both types of evidence, scientists can establish the evolutionary relationships between cheetahs and leopards and classify them into separate genera.
