In the analysis of a human disease and its pathology, researchers may apply different explanations, depending on the disease. If their interest is in the immediate mechanisms that cause the pathology, they will use explanations.

proximate

Explanation:

In evolutionary medicine, it is widely recognized that diseases have both proximate and evolutionary explanations that enable us to understand how natural selection may lead to the disease state.  

The questions raised under this idea are the following:  

- How is the mechanism leading to disease  

- Which is the ontogeny of the mechanism

- Which is the selective advantage of the disease state

- What is the evolutionary phylogenetics of the mechanism
