The wings of a bird and the wings of a beetle are considered as?
Correct answer: D. Analogous
- A. Taxonomic
- B. Phylogenetic
- C. Homologous
- D. Analogous
Explanation
The correct answer is " analogous." The wings of birds and beetles are considered analogous because they both serve the function of flight but do not share a common evolutionary origin. Analogous structures result from convergent evolution, where different species independently develop similar traits due to adaptation to similar environments or ecological roles. This contrasts with homologous structures, which have a similar origin but may serve different functions. The options 'Taxonomic' and 'Phylogenetic' are incorrect because they pertain to broader classification and evolutionary relationship studies rather than directly comparing the function or origin of specific traits.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.

The evolution of birds has long been a difficult issue for biologists until the discovery of the Archaeopteryx fossil in 1861. This ancient bird exhibited teeth, a long tail containing 20 vertebrae, and wings with movable fingers and claws. In light of the mentioned facts, who were the ancestors of the birds?
