Question

The forelimbs of birds are modified

• A. For walking
• B. For swimming
• C. For flying
• D. For grasping

Hint:

The structure of bird wings is highly specialized, including features like feathers and a lightweight skeletal system, which are all adaptations for flight.

Answer 1

The Correct Option is C

The forelimbs of birds have evolved primarily for flying. Over time, these limbs have undergone significant modifications, enabling birds to achieve and sustain flight efficiently. The wing structure is uniquely adapted to their lifestyle, providing the following advantages:

• The bones of the forelimbs are light yet strong, allowing for both strength and reduced weight.
• Feather presence aids in lift and control during flight.
• An aerodynamic shape minimizes air resistance.

The adaptive evolution of bird forelimbs illustrates the remarkable changes that natural selection can impart to meet environmental challenges and survival demands.
