Axiom V is "Current Biodiversity is the Result of Evolution." We can deduce Principle I from the following physical evidence, empirical observations or established theories which are part of Axiom V.
Current Biodiversity is the Result of Evolution
Devolution not Evolution
Evolution is Biblical. We'll lay out some logic for evangelical Christians so that they can avoid having heart attacks because we're telling you that evolution is Biblical.
Distribution of Biodiversity
There were two horses on Noah’s ark but now there are at least seven species in genus Equus. That's speciation or macro-evolution. It's not a problem because the process of evolution has a scriptural context.
Species Concepts
Understanding how the process of evolution incorporates into the creation narrative solves a lot of issues, not the least of which is the potential space problem on Noah's ark.
Extinction of Some Species
"Extinction of some species." Dead bodies buried in sediment from Noah's flood represent entire flocks, herds and populations of animals. If they were the only living members of their species, that's why they're extinct.
