There are two types of behavior:
- Innate behavior
- Adaptive behavior
Innate behavior is in-built, behavior, present by default. On the other hand adaptive behavior is what we learn to survive. For example, on a cellular level, our immune system has innate nature to defend us from germs but when it encounters a new type of pathogens, it develops immunity against it along time to keep our body protected.
Similarly in order to survive in a constantly changing environment, adaptability is important.
