I can see that you’re new to the Internet. Welcome!

That’s balance. Now the right half is just as fake as the proposed origin on the left.

Well, to be fair to evolution, surgeries weren’t really on its list of considerations. With no surgeries to the neck/chest it won’t be a problem at all. Most of us, including giraffes, have no problem with it and it works flawlessly. Is it a detour? Yes. But it works, and that’s the only thing that matters in evolution.

Your already can talk to animals. We all understand you.

Same line break on my screen. Thanks, that’s one more thing to blame.

Turns out I’m to drunk to read. Sorry, I misread the headline. Man, I hate english writing words separately…

Nope. The air pressure on the inside of a submarine is close to ~1 bar = ~1 atmosphere.

No? It’s the hull of the vessel that counters the outside pressure. The main reason to use a submarine, instead of scuba diving, is to shield yourself from the pressure. If the inside pressure was even close the the outside, which it would have to be to keep it from imploding, you wouldn’t need the submarine at all; you’d be crushed regardless.

At the depth of the Titanic, roughly 4000 m, the water pressure is ~400 bar. The record for highest survived air pressure is around 70 bar. That was for 2 hours, breathing a special gas mixture of 99,5% hydrogen and 0,5% oxygen.

I find it highly unlikely that they’d rely on the inside air pressure for anything other than the comfort of the passengers.

“catastrophic loss of pressure”?

Wouldn’t it be a catastrophic increase of pressure? They were at the bottom of the ocean.
