We're going to use the Cherubim as a case study of the benefit of using spherogenetic systematics as a deductive tool. According to scripture Cherubim have mostly mammalian, not reptilian, characteristics.
The Reptile-Mammal Transition
The reptile-mammal transition is abiogenesis not evolution. It's evidence that God created in a systematic manner of increasing complexity.
Abiogenesis not Evolution
The first day of creation included development of cellular and multicellular life which was capable of photosynthesis. This may seem far-fetched but it's in harmony with scientific theories of the origin of life.
Whether or not a Biblical word translated as a kind of serpent refers to something which may have been a dinosaur is context dependent. Sometimes a snake is just a snake. Sometimes a serpent is a Sauropod.
Extinction of Giant Land Reptiles
Behold Behemoth, a Sauropod dinosaur which lived in the Jordan valley during the time of Job and Abraham. Clearly not all of the giant land reptiles were made extinct by Noah's flood.
Voltziales and Glossopterids
"Rise of Northern Hemisphere Voltziales and diversification of Southern Hemisphere glossopterids. Extinction, arborescent lycopsids, and sphenopsids. Diversification of reptiles."
The Origin of Abundant Diversification
"Origin of reptiles, diversification of amphibians. Insects abundant." Here we can see how doublespeak is used to establish the premise that the evolution narrative envisions the development from simple to complex.
The whole of the narrative of Revelation 12 centers on the enmity, hatred, between Satan, the dragon, and the woman. If we apply the relationship of cause and effect we can again place this event after the fall of man.
The Fall is Coming
Something has to happen which changes an intelligent bipedal reptilian humanoid into a limbless snake. This happens in the context of changing the Earth from its newly created very good state into its cursed state.
After Noah's flood a wind caused the waters to evaporate. The cooling effect caused the formation of equatorial and polar ice. Temperate zones were in the mid-latitudes of the Northern and Southern Hemispheres.
