Conquest of the Post-Anthropocene seas.
Hello again, it's time for another illustrated post of speculative concepts. I had read a few times, in popular books about mammal evolution, that the transition to fully aquatic habits can show some convergences that may prove illuminating. For example, the earliest member of the seal and sealion group, looked much like an otter, and that the earliest whales swam like otters before they lost their hind-limbs. This invariably leads to the question, what will the aquatic mammals of today evolve into, in the future? What if all cetaceans went extinct? Would we have seal evolving into whale-like forms?

True seals do not swim like whales or otters, so really, they may evolve into something a bit more strange. They undulate their bodies sideways, with their back-feet forming a fin-like organ.So in this sens
