Wings of birds and that of flying lizards provide evidence of:

Explanation

Convergent evolution is the process by which unrelated or distantly related organisms develop similar traits or adaptations independently, often as a result of adapting to similar environmental pressures or ecological niches. This phenomenon leads to the appearance of analogous structures-features that perform similar functions but do not arise from a common ancestor. Classic examples include the wings of bats, birds, and insects, which evolved separately to serve the purpose of flight, and the streamlined bodies of dolphins (mammals) and sharks (fish), which both developed to move efficiently through water. Convergent evolution illustrates how similar environmental demands can shape different species in similar ways, despite their distinct evolutionary backgrounds.
