Medicine was especially well studied by Islamic scholars working in Greek thinker traditions, whereas natural history drew closely on Aristotelian thought, particularly in upholding a fixed hierarchy of life.

Evolutionary research is concerned with the origin and descent of species, and their change … Read More
