Question

why are birds considered more advanced than reptiles?

Answer 1

Birds are considered more advanced than reptiles because of the following reasons:

• They have four-chambered heart.
• They are warm blooded.
• Forelimbs are modified into wings and hind limbs have scales; used for walking, swimming, or clasping tree branches.
• They have the ability to fly because of the presence of wings (with exception of flightless birds).
