Convergent evolution occurs when unrelated organisms independently evolve similar (analogous) structures because they face similar selection pressures/functional demands, even though the underlying structures have entirely different developmental and evolutionary origins. Bird wings develop from the vertebrate forelimb skeleton, while insect wings are outgrowths of the exoskeleton (cuticle) -- structurally unrelated, yet both serve flight. This contrasts with divergent evolution (where a common ancestral structure diversifies into different forms/functions, producing homologous organs, e.g. the forelimbs of diffe …
