Despite 27 million years of dominating the oceans, the mosasaurs did not become radically different from their terrestrial lizard ancestors.  Both inside and outside of the water, they were always more akin to lizards than to any fish or other marine reptile. 

     The success of the mosasaurs is a testimony to an oft overlooked evolutionary pattern – namely, it is not necessary for a lineage to become radically different from its ancestors in order for it to succeed in a new habitat.  Mosasaurs did not need to become fish in order to succeed in the ocean.  They did fine just being lizards, and they even outcompeted the fish as successful predators. 

     Applying this to the Cambrian Explosion, one might ponder why so many different forms suddenly emerged in the Cambrian, for they did not need to diverge into such an array of various forms to fill new habitats.  Cambrian life could have retained the same basic structure of the most primitive phyla, cnidarians and sponges, and made only small adaptations over time to attain the full potential of those phyla.  There was no adaptive necessity for radically different structures to evolve in the Cambrian as they did.

     Besides mosasaurs, other terrestrial creatures have invaded the seas,  including whales, sea cows, sea lions, ichthyosaurs, plesiosaurs, and turtles.  Each of these comes from a lineage distinctly different from the others, which was originally terrestrial, and each retains many features of its terrestrial ancestors.  They have not become fish-like, nor have they converged to become like each other.  Rather, each has retained its unique structure from when it used to be terrestrial, and this remains true down through the aeons.  Nor did any of them develop the ability to breathe underwater as fish do, though it would be an evolutionary advantage for them to do so.  Why has evolution proved incapable of allowing sea faring reptiles and mammals to breathe under water as fish do?

When multiple lineages evolve to fill the same habitat, there is no rule that they must become similar to each other.  This fact is seen not only in marine reptiles, but in winged animals too.

The creationist narrative in Genesis 1 is contradicted by many ancient Christian texts.  Instead of an Almighty Creator God, ancient Christian texts espouse that the universe is born from blind arrogance and stupidity.  The angels caused evolution to occur from species to species.  There are many gods, (or aliens?), and the Christian God is just one among them.  Satan the Devil writes scripture, and thus the Bible was polluted with Genesis 1.  Archaeology and modern scholarship demonstrate that Genesis is indeed corrupted.  Cavemen walk with Adam and Eve.  Esoteric prophecies reveal the coming of Christ, and also reveal the dark forces that govern the cosmos.  Such are the ancient Christian writings.
