Scientists have offered a first look at some of our pre-historic relatives, the Denisovans, so it seemed.
The researchers, led by scientists at the Hebrew University of Jerusalem, and have reconstructed it in the Denisovan skeleton of the animal.
While a lot is known about the Neanderthals because of the many remains discovered in Europe and Asia, some experts note that the Denisovans are still shrouded in mystery. “Denisovan remains were first discovered in 2008 and is inspired by the human evolution and to researchers ever since,” he said, the Hebrew University, in a statement. “She was living in Siberia and East Asia, and became extinct about 50,000 years ago. We still don’t know why.”

With this in mind, there is a great deal of uncertainty about the Denisovans’ physical characteristics. “And this is exactly what our Denisovan relatives could have been like as a person, it is recommended to have a simple reason for this: the whole of the collection of the Denisovan remains, consists of three prongs, of a pinky bone and a lower jaw”) Hebrew University, explains.

In an effort to shed new light on the Denisovans, the experts studied the methylation, or chemical changes in the DNA, in the development of their reconstruction of the long lost human ‘cousins.’
“We provide the first reconstruction of the skeleton of the anatomy of the Denisovans,” said Hebrew University Professor Liran Carmel, who is the study’s lead author, in a statement. “In many ways, Been looked at, that all of Humanity, but there are some traits they looked at us, and in others, they were unique.”

Carmel, and his co-investigators have identified a 56 anatomic features that Denisovans differ from those of modern humans and the Neanderthals. 34 of the positions are in the place of a skull, with experts noting that the Denisovans’ skulls are likely to be larger than that of a human and the neanderthal man. According to their research, the scientists believe that the Denisovans had a longer palate, and a pronounced chin.

The researchers spent three years studying the chemical changes that have an impact on gene activity, but do not address the underlying DNA sequence, and compared them with the human and the neanderthal man. “So, we’ve got a prediction of which parts of the skeleton may be influenced by the differential regulation of each gene and the direction in which that portion of the structure would have to change to a longer or a shorter femur bone,” study co-author David Gokhman, D. Ph. explain.
The study is published in the journal Cell.
In a separate project, which is a a tooth has been excavated from the Denisova cave in Siberia’s Altai Mountains, in 2010 it was extended and analyzed. Findings released in the year 2015, showed that the Denisovans were much earlier than anyone had expected.

Earlier this year, in another case, researchers found that of a Denisovan finger bone, and bears a closer resemblance to a human finger, a leg, than a Neanderthal’s.
