i can't, nobody can, that's not the point. the point is not to "prove" anything, the point is to understand how life is shaped by properties of 3d space, properties of molecules, properties of genes and how they are transmitted from one individual into the next. it's like trying to see what a marble statue looks like, but all you have are the pieces that have been chopped off by the sculptor, not the actual statue. you can reconstruct the entire block of marble around the statue and see the "shape" that is left by the empty space. this gives you a reasonable approximation of what the statue might have looked like, but you will never be able to see the statue itself. based on many of this "bits of marble" that have been assembled, we can begin to have an idea how a horse might have developed from a fish and say "hmmm there is a reasonable likelihood this model describes that happened", but then you challenge that idea and look for weaknesses in the model, you look for more "bits of marble" that make the image just a bit clearer. so it's not about "proving" anything. in any case:   doi/10.1098/rsos.171782
