Theories on Evolution.. Scale of Nature..

Way back many years ago, even leading back to the time of Aristotle, several scientists gave studied and proposed their theory on evolution.

One of the first scientists who have studied evolution was Aristotle. Hr proposed a theory on evolution named the "Scale of Nature."

Scale of Nature- this theory of Aristotle's states that species are arranged in a ladder-like order where the inanimate matter(non-living things) is on the lowest step while the human was on the highest.

Chain of Being- another influential philosopher at the time of Darwin, nature exists in an orderly ladder or "Great Chain of Being." At the bottom of the ladder is inanimate matter (i.e. dirt and rocks). At the top of the latter are immaterial, spiritual beings like the gods. Half way up the ladder are humans--half material and half immaterial spirit.
