The shrimp's protein and ours are not exactly the same, but they're sosimilar that if you turned up in court and tried to convince a judge that yourversion was not a badly concealed plagiarism, you'd be very unlikely to win.In fact, you'd be a laughing stock, for rhodopsin is not restricted to vent shrimpand humans but is omnipresent throughout the animal kingdom.... Trying to persuade a judge that your rhodopsin is not plagiarisedwould be like trying to clajm that your television set is fundamentally differentfrom everyone else's, just because it's bigger or has a flat screen.
