The Unani Concept of Mizaj (temperament) and its Correlation with Biodiversity in Present Epoch- A Review

Global biodiversities are very important characteristics of nature, which provide different variability among living organisms to all geographical areas including, terrestrial, marine, and other aquatic ecosystems etc. The origin of life as well as biodiversity on the earth was being the issue of contemplation up to now. In BC centuries, Greek philosophers also proposed different ratiocination regarding the same. They provided the knowledge about biodiversity and ecological system and what factors which are essential for their maintenance. Ancient philosophers explicated that the diversity within the species and ecosystems is based on the four basic constituents (fire, air, water and earth) and their temperament (hot, cold, dry and moist). Thus, this paper aims to interpret the significant thoughts of Greek philosophers with the present rational era of ecological knowledge.
