Dr Wills said it had been amusing to watch the internet debate unfold, but "the answer is still no", humans will not evolve into crabs.
"The convergent evolution of crabs has happened about five times in history, but it's happened within the group of decapods."
I am skeptical
But at least four groups of decapods - including sponge crabs, porcelain crabs, king crabs and the Australian hairy stone crab - are "imposters" that have gradually transformed their shape by tucking their tail underneath.
Have we not already began this process by losing our tail? Do men not often spread their legs out as widely as possible to feel comfortable?
