Hi there, the only question I can answer is regarding the inventor of fins. The first patent on fins was taken out by the Frenchman Louis DeCorlieu in 1933. Owen Churchill, an American, patented improvements to the fins and distributed them in America under a contract with DeCorlieu.
Before that, Leonardo Da Vinci drew up some designs for swim fins. Tahitians were diving with home made rubber fins for ages when Churchill bought a pair, giving him the idea to patent them in 1938 (too late...Louis had already patented his fin).
This reflects the Western idea of history....similar to Columbus' or the Norwegians' "discovering" of America, with not too much regard for the fact that civilizations had lived there for 1000s of years before Europeans "civilized" them.
I suspect that people have been strapping fins on for thousands of years.
Good luck with your paper, and keep us posted with your development of new fins!
Cheers,
