Explanation / Answer

The explanation for disease processes in context of,

Proximate is the immediate reaction that is caused by the diseases. For example, respiratory infections

Developmental method explains different stages of infections that took up the form of disease

Evolutionary approach of disease explains the adaptability and process of evolution

Phylogenetic approach explains about the family tree of the disease

2. Three examples: Evolution, limitations, and time period

3. Coevolutionary arms race can be applied to both humans and their pathogens, as the survival of the pathogens is purely dependent on the host. Hence, the pathogens evolve to stay live by making the host sick but too sick that will make the host to die.

4. Three explanations: Trade-off for reproduction, no selection on post reproduction, and trade-off for speedy harvest
