I love your thoughts, as you know, its about about creating thought.
Lets look at it another way.
Back then, these animals were nothing like they are today and their ranges are nothing like they are today. At one point, they started from a common ancestor. As they evolved, we have no idea, what they looked like or if what we call morphs were a normal phenotype.
Many colubrids must or may have evolved from a common ancestor. As they have no genetic problems interbreeding. So species divergence must be fairly recent.
These are just examples, but its clear, that what we see today, is not what was here even in the fairly recent past.
When species migrated, the environment must have been very consistent to allow that. Then the climate changed and cause localized adaption as needed to exist.
The truth is, all we have is bones, so no color or pattern types are known from the past. ALso because the environment was different, we have no idea what was phenotypic. Thanks for the conversation and your thoughts
