How the hell do fish "evolve" and "mutate" to where they can go from only breathing underwater to being able to breathe oxygen on land?
It makes no sense.
I watch a lot of cable television so I'm pretty sure I'm qualified to address this query.
The first ones that came out of the water would basically just slide around on the mud to eat muddy things in the mud. It would then return to the water to breath. Or whatever breathing is called underwater. Over time it could "hold it's breath" longer and longer until eventually it just stopped going back to the water to breath and started hunting with tools.
Disclaimer:
I have know idea if that's accurate. I just made that shite up.

No, that would be like saying if you shoot a bow and arrow a lot, you'll adapt to shooting a bow and arrow over generations.
What happens is a mutation occurs or there is genetic trait which makes you mo betta at shooting a bow and arrow. Like really fawking strong shoulders..freakishly strong. Then you kill lots of animals and live and pass on your genes while chicken arms boy dies because he couldn't hold his bow up as long and missed animals. So, his genes die with him.
Take the fish. There is a mutation that allows some air to be processed in the gills (ie...primative lungs) so the mud fish can stay out of water longer, not hold his breath longer. Although, that could be a trait selected for as well. Well, lungfish lives through droughts and gillfish dies. Now you have a primitive lung passed on...and so on.
Need to see over tall grass to avoid the big toothed predator...tall neck horse is going to live while short neck dies. Necks get longer as more of the longer necked ones live and shorter necked ones die.
