Have you ever wondered if this is how we, as in humans have always looked? Yes, of course, we all differ in our appearances, but what if the ancient humans had an altogether different look?
A recent article on the internet about the ancestors of the present-day humans, and their traces still being present in a few of us compelled me to find out more about the ancient versions of us and how they looked.
The recent discovery of a reconstructed jaw in a cave in the Philippines, which is said to be quite different from the remains found till now, has led to the study of the most ancient form of human existence, termed the Denisovans. The Neanderthals, also a part of the vast human variations are similar to them as they are related, but what’s more fascinating is that in spite of being closely connected to the Denisovans, the present human features share a great percentage of similarities with the Neanderthals.
The information we have acquired till now is still inadequate to find out in-depth about the Denisovans, but the only proof of existence or determination of this species until now is given by the teeth, finger bones or minute fragments that have been found in the Siberian caves which were believed to be their habitat.
As suggested by archaeologists and studies conducted, the rigid structure of the teeth and other parts found are in such a way, so as to protect them from the high-altitude temperatures in Tibet.
Researches carried out in the areas of New Guinea panning over to Tibet and China claim that the modern humans residing there have acquired about 3%-5% DNA of the Denisovans.
But the most interesting point here is the common link between the Neanderthals and the Denisovans who share a common ancestor, Homo heidelbergensis, who originated in Africa. The study reveals that Homo heidelbergensis who moved to Asia evolved as the Denisovans, and the ones that migrated to Europe had turned into Neanderthals. And the ancestors who stayed back in Africa are the homo sapiens, which are of our kind.
Digging into various previous news revealed that the first discovery of the Denisovan existence was in the year 2008, when a few Russian paleoanthropologists found a tiny fragment of a finger bone that belonged to a girl aged between 5-7 years old who might have died 40,000-45,000 years ago and DNA tests were conducted on this fragment by the Max Planck Society. The research conducted by them stated that the genomes of this girl were compared to various genomes of modern-day humans and the Neanderthals and it showed several similarities between them. After these findings, the scientists have also come up with assumed facial features of Denisovans or how they might have looked like- a flat nose, big forehead, and hard built hands. They were capable of bearing extreme cold temperatures and were rigid in their physique.
Imagine, if just with the unearthing of a few fragments and a jawbone, a new yet ancient human species could be found, how many more would there be left to be discovered? It all remains to be seen if the Homo sapiens, are the only ones we can relate to or could there be more we never knew of? Only time will tell.

You might want to discuss Australopithecus too, who we have known for very little. (He being 4million years old ). A skull of his, Nick named MRD , found in Ethiopia,from which we could draw how his eating habits were, his height ,consequently the evolution.
