Question: Bird wing and butterfly wing analogous or homologous?
Bird wings and butterfly wings are analogous structures, meaning that they have a similar function but evolved independently in different lineages. Bird wings are modified forelimbs with a complex bone structure and feathers, while butterfly wings are membranous and covered in scales. They do not share a common ancestry and have evolved separately in response to similar selective pressures for flight. While they both serve the function of flight, their structures and origins are fundamentally different, and they are not homologous structures.
