How can pharmacology benefit from the concepts of evolutionary principles and adaptational mechanisms?

Pharmacology as a modern science tends to combine many disciplines both within its theoretical aspects and practical applications. Indeed, pharmacology, benefits from both studies and results obtained in other fields such as traditional medicine (Ghanemi and Boubertakh, 2015), genetics, physiology and zoology (Ghanemi, 2015). Pharmacology is even very close to some specialties such as toxicology (Ghanemi, 2014a,b) and biology. The current situation strongly links pharmacology with numerous modern sciences within the context of current finding and discoveries.
