There are several ways that scientists provide evidence of evolution, including comparative anatomy, comparative embryology, and fossils. Comparative anatomy looks at homologous and analogous structures between species, while comparative embryology examines similarities in development. Fossils provide direct evidence of extinct species and how they changed over time. Scientists use both relative dating of fossils layers and radioactive dating to determine the age of fossils and track changes in species. Adaptations like camouflage and mimicry help organisms survive and reproduce more successfully.
