Pretty much, yeah. And we have a very good fossil record demonstrating that progression.
Marine mammals are indeed still evolved from reptiles. They are secondarily aquatic. All marine mammals evolved from terrestrial mammals which in turn evolved from synapsids which evolved from reptiles.
@Pikachu Wow, the idea of secondarily aquatic just kinda excites the mind and thinking about that transition of switching from land to sea over time...

Even the Bible teaches evolution =
Wisdom 19:18-21 (CEB) = "18 If we are careful to observe events, we can see just how the elements of the universe are transformed. It’s the same transformation that happens when someone changes the sounds that a harp makes by changing the key while continuing to play the same melody. 19 In this way, land animals were changed into underwater creatures, while animals that swam in the waters now moved onto the land. 20 Fire was able to burn on the open water, while water forgot that it was supposed to put fire out. 21 Flames no longer burned the exposed flesh of living beings, who were able to walk through the flames. Flames didn’t even melt the frostlike crystals that were a kind of food of everlasting life."
