Consider the different forms of evidence scientists use to support the evolution of species. In 3–5 sentences, describe two forms of evidence scientists might use to analyze how alligators and crocodiles evolved from a common ancestor.(4 points)

Answer 1

Scientists use fossil evidence and comparative anatomy to analyze the evolution of alligators and crocodiles from a common ancestor. Fossil evidence provides insights into the morphological changes over millions of years, showcasing transitional species that exhibit characteristics of both groups. Comparative anatomy involves examining the similarities and differences in the skeletal structures and physical traits of modern alligators and crocodiles, which can reveal homologous features that suggest a shared evolutionary history. Together, these forms of evidence support the understanding of how these reptiles have diversified while retaining traits from their common ancestor.
