Question

why is the carpals, metacarpals, and phalanges are fusion together in birds. What environmental pressure likely caused this evolution change?

Answer 1

In birds, the carpals, metacarpals, and phalanges have fused together to form the carpometacarpus, providing strength and stability for flight.

Step-by-step explanation:

In birds, the carpals, metacarpals, and phalanges have fused together to form a structure known as the carpometacarpus. This adaptation is believed to have evolved to provide strength and stability for flight. The fusion of these bones reduces the number of joints and increases the rigidity of the wing, allowing for more efficient and coordinated flight movements.
