I was just listening to eons in my car and specifically the episode about armored fish, and the thought occurred to me: isn't evolution ultimately selecting for adaptability? (m.youtube.com)

It would seem the design that can survive the most extinctions would be the clear winner in the end.

A coastline absolutely can vanish(submerged) or be against geography, such as rocky cliffs, that is unsuitable. "Coastlines can't stop existing, only move" is semantic nonesense.

EDIT: for ya downvoters, where's the coastline on an island that vanishes due to rising sea levels? The Marshall Islands have a max elevation of ~7' and are already having issues with rising sea levels. When the sea rises above them, where does their coastal ecosystem go?

If a coastline submerges a new coastline is created further inland. ie, it moved. Or are you proposing a situation where all land is submerged?

You’re right, a beach can be replaced by cliffs that a crocodile wouldn’t be able to make use of. That’s a good point.
