Seriously, how cool would it be to be able to breathe underwater? The possibilities seem endless. We could swim around coral reefs indefinitely. We could play with dolphins without drowning. We could find out what Ringo Starr was trying to tell us with "Octopus's Garden." But as fun as undersea adventures would be, how would having gills affect our day-to-day life?

Surprisingly little. Unfortunately, primates aren't really suited to aquatic living. Our limbs are inefficient for swimming. We don't have enough body hair and subcutaneous fat to spend much time in the water before we are dehydrated and get hypothermia. On top of that, most lakes and rivers aren't clear enough to let us see underwater. Swimming in clear, shallow water in the ocean is fun, but for most islanders there'd be little to do besides sit on a few hundred meters below the surface without the protection of a submersible. Oxygen from our gills would keep us from blacking out as we moved deeper, but below 200 meters or so we'd reach the bathyal zone, where it's dark and the water is 59 degrees Fahrenheit or colder [source: Britannica].....
