text: how do you think the sport of swimming orginated? and why do you think people keep participating in the sport? who invented it? why do you think it was needed in the first place? who benifited from it the most?? who 'invented' swimming?    why was it needed? are you kidding? can you really be this thick?  ok.  swimming was invented by microorganisms who thought it would be a good idea to move about in the water to find food and get some exercise.  these little critters evolved (okay i skipped a bit) into human beings.  cavemen (and women) probably swam to catch food or to escape predators.   people keep swimming today because it's just so darn much fun, and an important survival tool.  duh.
