      Do you think this would be particularly useful? If you can’t think of a specific survival or reproductive advantage to this behaviour, then it probably didn’t evolve for that reason… So, aside from the fact that we are big and heavy and walking on water would be tremendously difficult…behaviours tend not to evolve unless they are useful.
