1. Adaptive radiation: A pattern of evolution in which slightly different species evolve from one common ancestor.
2. Coevolution: A pattern of evolution in which two species evolve in relation to each other.
3. Convergent evolution: A pattern of evolution in which similar characteristics evolve between two unrelated species.
4. Divergent evolution: A pattern of evolution in which very different species evolve from one common ancestor.
5. Gradualism: A theory of evolution that states that a species evolves by consistent, small, steps.
6. Punctuated equilibrium: A theory of evolution that states that a species evolves in spurts of rapid change and then no change.
If the inner lining of the air sacs neither thin nor highly vascularized, then it can be inferred that AIR SACS ARE CANNOT BE THE SITES OF GASEOUS EXCHANGE BETWEEN AIR AND BLOOD. Air sacs are generally lined with mucus and surrounded with blood capillaries.
In case of birds, air sacs play an important role in respiratory system.
