A new study, published on Tuesday in the journal Nature Communications, has discovered that human hands could be very similar to those of the last common ancestor of humans and chimpanzees – with chimps displaying even more dexterity. The concept that advanced humans and knuckle-dragging apes is evolving. Before, many believed that human beings started out with chimp-like hands but these eventually groomed over time as humans started using tools for daily chores.
Researchers from Stony Brook University found that early human relatives like Ardipithecus ramidus, which lived 4.4 million years ago, had hands similar to our own. In fact, human-like hands — which have long thumbs compared to their fingers — may goes as far back as 6 million years. Evidence of tool use only goes back 3.3 million years.
It indicates that human hands have reformed little since the human-chimp evolutionary split. Chimp hands, however, have evolved a great deal.
We aren’t alone in our primitive state. Gorilla hands are also very similar to those of the extinct creature that links man and ape.
