Question: Enumerate three evidence of convergent evolution to show that birds might have descended from reptilian ancestors?

Convergent evolution is the process by which unrelated organisms evolve similar traits or adaptations in response to similar environmental pressures. One way to investigate the evolutionary history of birds is to look for evidence of convergent evolution with their reptilian ancestors. Here are three examples of such evidence:

- Feathers: Feathers are modified scales that provide insulation and enable flight in birds. Some fossil reptiles, such as Archaeopteryx and Microraptor, also had feathers, suggesting that they were an ancestral trait that evolved before the divergence of birds and reptiles.

- Bones: Birds have hollow bones that reduce their weight and enhance their flight ability. Some fossil reptiles, such as Coelophysis and Pterosaurs, also had hollow bones, indicating that they were an adaptation to a fast and agile lifestyle.

- Eggs: Birds lay hard-shelled eggs that protect their embryos from dehydration and predation. Reptiles also lay hard-shelled eggs, implying that they share a common reproductive strategy that originated in their ancient ancestors.
