10 Ways Humans Would Look If We Had Evolved Differently

Evolving To Live Underwater

Geologic findings show that the evolutionary branch of fish separated from terrestrial vertebrates 400 million years ago. From that point to now, aquatic life-forms have differentiated themselves in significant ways from humans.For that reason, if we wanted to live underwater, we would need a lot of physical changes. Fortunately for us, scientists have described several ways that humans would appear in an underwater world.Starting with the theory with the lighter changes, humans would have longer fingers with skin connections between each finger. Thus, we would become palmipeds like ducks. Our eyes would develop a special membrane to see in low-light conditions, just like cats. In addition, we would have much less body hair to move faster through water and we would store more fat to withstand the cold of the watery depths.A more “hard-core” theory also suggests that humans would be web-footed. But their legs would join in a single limb, like a fish tail, to save more energy when swimming.However, the most extreme description of “aquatic people” states that they would have gills along their chests. Meanwhile, their legs would be like fish fins and their arms would remain the same as those of humans.[7]The neck would be connected almost to the back of the head so that the creature could see forward while swimming in a horizontal position. This would cause the human living underwater to have a frog-like face and communicate with simple grunts.
