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.Nick Lane

We should not be too quick to dismiss our own [ocular] arrangement. As so often in biology, the situation is more complex...we have the advantage that our own light-sensitive cells are embedded directly in their support cells (the retinal pigment epithelium) with an excellent blood supply immediately underneath. Such an arrangement supports the continuous turnover of photosensitive pigments. The human retina consumes even more oxygen than the brain, per gram, making it the most energetic organ in the body. .Nick Lane
