→ Darwin believed that the need to adapt, in similar words, the changes occruing in the environment caused evolution.
The main cause of evolution, according to Darwin, was natural selection. Natural selection is a process in which a group of organisms with certain characteristics survive and thrive, in comparison to other organisms with different characteristics. This idea basically means that having some characteristics makes you suited for an environment.
And how would that ↑ explain Evolution?
Well, evolution is the change in species that occurs during time. But for you to change, there must be a cause for that change, which is none other than the need to survive, reproduce, etc.

Explanation:
Innate immunity is the nonspecific immunity. These immune defenses are present at birth and do not involve specific recognition of a microbe. Being nonspecific in nature, it acts against all microbes. Innate immunity includes the first and second lines of defense.
Some of the examples of components of innate immunity among the first line of defenses are physical and chemical barriers of the skin and mucous membranes. Innate immune responses are the immunity’s early warning system that is generated immediately after the encounter with a pathogen to prevent them from entering the body and to help eliminate the ones that have entered the body.
Once a microbe has entered the body, secretion of antimicrobial substances and activities of natural killer cells, phagocytes, the process of inflammation, etc. serve to eliminate it from the body. All these responses are the components of innate immunity.
