Convergent evolution is a biological phenomenon where unrelated species develop similar traits or adaptations due to similar environmental pressures. This process occurs when different organisms face comparable challenges in their habitats, leading them to evolve similar solutions, even though they do not share a recent common ancestor. A classic example of convergent evolution is seen in the wings of birds and bats. Although these animals belong to different groups, both have evolved wings to enable flight. This similarity arises not from shared ancestry but from adapting to the same functional need in their respective environments.
