Two types of immunity systems, innate immunity and adaptive immunity. Adaptive immunity is formed when it is exposed to a harmful substance, vaccines for example create adaptive immunity.
Innate immunity is present at birth which consists our skin protects us physically, chemical substances in our blood that protect us from bacteria and infections and also our blood cells such as T cells.
Since innate immunity forms one of the first lines of defense in our immune system and is the first to respond to a threat in a few hours down to as little as minutes, it is not slower than adaptive immunity in its response to infections and pathogens.

Answer:
coevolution
Explanation:
Coevolution refers to the process where two or more species modify each other's evolution via natural selection. Darwin mentioned how insects and flowering plants could coevolve by reciprocal evolutionary modifications. Coevolution has firstly been associated with mutualism between species including, for example, birds and flowering plants. However, coevolution may also involve host-parasite relationships, such as associations involving parasitic organisms and their sexually reproducing hosts. Finally, there are situations where coevolution involves both parasitism and mutualism (i.e., antagonistic coevolution).
