The term for the phenomenon where similar traits arise in unrelated lineages is convergent evolution. This occurs when different species independently evolve similar solutions to similar environmental challenges. For example, the wings of bats and birds serve the same function but originate from different evolutionary backgrounds. Convergent evolution highlights how similar environmental pressures can lead to analogous adaptations, providing insights into evolutionary processes and the concept of functional morphology. It explains the diversity of life forms while showcasing how organisms can exhibit similar traits under specific ecological contexts.
