If Fish Had Hands

The origin of species from a common descent is compelling, as is speciation, multiplication and diversity over eons.

Evolution can occur without morphological change; and morphological change can occur without evolution.

Yet I never imagined an operatic mermaid could move me to tears.

One can't say humans share common ancestry with mermaids for the same reason reputable scientists are skeptical about fairies.
There may be fairies at the bottom of the garden. There is no evidence for it, but you can't prove that there aren't any, so shouldn't we be agnostic with respect to fairies?
~Richard Dawkins
That is why I am trying to be agnostic with respect to humans descending from butt-ugly fish.

Still, the evidence is compelling.

Fish and humans have many of the same organs, a digestive system and a reproductive system.

But humans breathe through opposing nostrils while fish breathe through opposing gill slits.

If fish had hands, would they pinch their gills when they jumped out of the water?
