He added: “This is the first time that we have unequivocally discovered fingers locked in a fin in any known fish.

“The articulating digits in the fin are like the finger bones found in the hands of most animals.”

The evolution of fishes into tetrapods — the group of four-legged vertebrates to which humans belong — is one of the most significant events in the evolution of life.

Vertebrates with backbones could leave water to eventually conquer land.
