Which one of the following characteristics is not shared by birds and mammals?

  1. Viviparity
  2. Warm blooded nature
  3. Ossified endoskeleton
  4. Breathing using lungs

Answer

(1) Viviparity

Solution

As per NCERT, birds are oviparous, while mammals (with a few exceptions) are viviparous.

∵ Both birds and mammals are warm blooded (homoiothermous), have an ossified (bony) endoskeleton and breathe by lungs,

∴ viviparity is the characteristic not shared by them.
