🐻 Could dolphins evolve to live on land?

The oceans are teeming with tetrapods—“four-legged” birds, reptiles, mammals and amphibians—that have repeatedly transitioned from the land to the sea, adapting their legs into fins.

Coming straight onto land is only an evolutionary pressure for the dolphin as is, if the sea has become very inhospitable at which point a lot of a dolphin's intelligence will likely be sacrificed first. Instead consider that dolphins first become tool users.

The rationale is that their best food source was in the water (when they were land animals) and thus they spent so much time in the water that they gradually adapted to it.

It is difficult to answer the question “Why did marine mammals go back to the sea?” Remember that evolution by natural selection facilitates tiny changes generation by generation allowing ...

Again beached dolphins often end up stuck on the sand and are unable to return to the ocean because they are incapable of walking on land or, in the case of a beached dolphin, back to the ocean.
