To adapt to a 'water world', Dr Skinner expects humans would develop webbed hands and eyes like those of cats to help us see in the poor lighting conditions underwater.
We would also retain a layer of baby fat into adulthood as an insulator for spending long periods submerged.
Regular foraging in shallow waters could lead us to develop artificial 'gills' to help us breathe, extracting oxygen from the water and delivering it to the bloodstream.
This would also lead to our lung capacity becoming greatly reduced, and our rib cages shrinking.
An additional layer in the retina - like cat's eyes - could develop to help us see in poor light under water. We might also evolve an extra translucent eyelid to protect the eyes from water.

Now PANIC --- and go check yourself.. Could wake up tomorrow and find yourself foraging in shallow waters without FLIPPERS and a SNORKEL.



Nope.. Nobody is HYPING the claims for GW.. Nah uh.. Doesn't happen. Except I wager the good Prof got a bag of GW gold grant money for producing that entertainment.
The INTERESTING part of this work is how much Darwin DIDN'T know about evolution. Since it's generally agreed on now that massive genetic changes can occur VERY RAPIDLY. Even spontaneously in the timeframe of evolution or climate.
