If you are implying one these choices not needed for survival it would be parents only when you can survive on your own (I'm not that sure but I hope this helped the slightest but)

Explanation:
The immune system develops integrated innate and adaptive modules that are pathogen type-specific and no single response can effectively control all types of pathogens
Both innate and adaptive immune system operate in cooperative and interdependent ways
Innate immune system is present since birth in an organism and is non specific in nature which means acts against all foreign antigens and molecules and provides first line of defense against pathogens
Adaptive immunity system is the acquired one which is capable of recognizing and selectively eliminating specific foreign antigens and is antigen specific which means can discriminate among different antigens; also has the ability to respond to various kinds of epitopes of pathogens
These structures are called Vestigial structures, they resemble structures from the organism's ancestors, but don't have a real purpose for them now.
Pray this helps you :)
