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.

Answer 1

Scientists use fossil evidence and comparative anatomy to analyze how alligators and crocodiles evolved from a common ancestor. Fossil evidence provides insights into the physical characteristics and timeline of species that existed before modern alligators and crocodiles, allowing researchers to trace their evolutionary lineage. Comparative anatomy involves examining similarities and differences in the anatomical structures of alligators and crocodiles, revealing homologous features that suggest a shared ancestry. Together, these forms of evidence help scientists understand the evolutionary processes that led to the diversification of these reptiles.
