Humans evolving from fish!?

If humans evolved from fish, why can't we breathe underwater?

Humans actually didn't evolve from "fish", the idea of "fish" doesn't even make sense. As was well pointed out in the Oxford Encyclopaedia of Underwater Life, a salmon is more closely related to a camel than it is to a hagfish. So if the concept of a fish does exist than a camel must be a "fish", infact all living things must also be "fish"!!! So if camels are "fish" and they can't breath water hence why should we as "fish" derivatives, "fish" ourselves be able to breath water!!!
We do actually have gills, but they only activate when you are severely oxygen starved. Try holding your breath underwater for at least ten minutes to activate your gills for the first time.

Just because we evolved from fish doesn't mean we can breathe underwater.

Suppose there are mutations, evolutionary advantageous mutations that cause a different species, and that species is "evolved".

Now suppose there are more mutations, gradually changing groups of animals until they are different species.

These different species have different mutations that eventually cause them to split into separate species.

These mutations can cause different traits/advantages/disadvantages to be expressed, evolutionarily. Therefore one trait that can be an evolutionary advantage or possible in one species can be an evolutionary disadvantage or even impossible in another species (and therefore weeded out).

For example, breathing underwater.
