1. Simple life to complex
	"…the most ancient strata in which fossils are formed would contain the most primitive forms of life capable of leaving a fossil record." (Gish, p.41)
2. Complex life always following simple life-forms
3. Transitional forms in a "continuum" from simple life to progressively more complex life forms
4. Newly emerging types of life would retain characteristics used to define the ancestral group
	"(T)he criteria we use to classify plants and animals today would be less and less useful as older and older fossils show the in-between characteristics of presumed common ancestors for different groups." (Morris, H and Parker p.125)
5. Many examples of "bad designs" which were replaced by more highly evolved forms
