Species are fixed on a continuum from simple designs to more complex designs. All living forms could be arranged on this ladder. Each group of organisms was fixed, permanent, and did not change. Believed that species were created, then evolved. Discovery of the creator"s (god"s plan) through the study of nature. Developed taxonomy (classification hierarchy for naming organisms) Binomial system of naming organisms (genus species) Profound change is the cumulative product of slow continuous processes.
