Most Wings Are 'Good Enough'

A Nature Communications study built a theoretical space of possible wing shapes, evaluated flight performance across modes, then mapped real bird wings onto that space and found most species fall far from the theoretical performance optima. Some groups (hummingbirds, penguins) align with high‑performance solutions, while many everyday birds occupy middle or low optimization ranks, suggesting constraints and trade‑offs (including non‑flight uses like display) shape wing form. — Shows evolution often yields satisficing (good‑enough) designs, a corrective to teleological public narratives and a practical warning for engineers using biological form as a shortcut to 'optimal' solutions.
