Yup, unless we start to live in water 24/7 and do so for millions of years, we are not going to develop gills...
I remember reading a few years ago about a liquid that can be put into the lungs to stop them collapsing under massive pressure, linked up to a respirator with the said liquid, and lungs full of it, you could breath it.
However, i imagine the transition between air-liquid would be somewhat uncomfortable!!
We can?

Yes, although it's not something you could do while walking down the street

I'm pretty sure liquid breathing is real. If there's a high enough concentration of oxygen in the liquid, and not much else that could be absorbed into the bloodstream then it's possible you could breathe it.
According to Wikipedia there have been experiments done for medical purposes.

thats easy to get around you just put a tube down the persons throat.
The notion we got our ears from fish is... an interesting one. I'd go off on one about the reptilian jaw bones and transitional fossils but I doubt anyone would care.
As for gills, they'd be useless on us. We'd near gills like parachutes to get enough oxygen into our system. Mammalian physiology burns oxygen a hell of a lot faster than fish or reptile physiology so we need more of it. We can get it from air because air contains a much higher concentration of Oxygen than water.

Correct!
Yeh i suppose our bodies aren't very efficient in how we use up oxygen, however, we can adjust it to an extent. Take a Kenyan (average) and an American (average) and judge how much oxygen each one requires and absorbs. The Kenyan, due to mountain climate (if in the mountain region) will absorb oxygen much more efficiently and need much less.
Same as some people can hold their breath for upto 9 minutes.
We devolved our gills...
