Which of the following orders is classified by arm, hand and extra long finger bones covered with a membrane which resembles a wing?

The order classified by arm, hand, and extra-long finger bones covered with a membrane that resembles a wing is Chiroptera. This order includes bats, which are uniquely adapted for flight. The term "Chiroptera" translates to "hand wing," reflecting the anatomical structure of their wings, which are formed by a flexible membrane, or patagium, stretching between their elongated fingers and body.

Bats possess this specific wing structure, which allows for a wide range of motion and maneuverability in the air. This adaptation is crucial for their feeding habits and predator evasion. The ability to control their flight through their fingers is a significant evolutionary advantage.

In contrast, the other orders mentioned do not share these adaptations. Accipitriformes includes birds of prey such as eagles and hawks that have wings structured differently, primarily based on the alignment of feathers and wing shape suited for soaring and gliding. Galliformes comprises ground-dwelling birds like chickens and turkeys that have robust bodies and shorter wings adapted for short bursts of flight. Passeriformes, or perching birds, have a descended foot structure for gripping, which contrasts with the wing structure of bats. Thus, the specialized anatomy and adaptations of Chiroptera
