I kinda agree with the GP that this seems weird. Yes, ocean temps are rising very quickly, but this experiment only took 5 years, and was presumably a only a tiny fraction of how many wild coral there are. Ocean warming has taken place over several decades, and with millions of times as large of a natural population. It just seems weird that, if this kinda of adaptation is possible (and they showed it is), it wouldn't be happening in the wild. And that does seem to be true, it just seems weird.
