The finding reported (well, derided and oversimplified for Luddites) was apparently not totally unexpected.

Great pictures. There's been a lot of important work in this area. Just to clarify for the current context, the shrimp would have diverged from the same putative ancester and evolved tail segmentations beyond the ones shown.

Consider that in going from being a shrimp to being an insect, you have to first leave the water, or at least learn to breathe while not in it.

That suggests a simple experiment: Go to your local fishing and tackle store and buy yourself a couple of dozen bait shrimp, put them down on the floor in your garage (i.e. out of water), and come back in two or three hours and see for yourself how many of them are still alive.
