Some of our assholes are known only from very few fossils, such as the jaw piece somewhere in the heel bone. In such cases, it is up to us to portray the story of human evolution. However, this story begins to be rewritten with fascinating current findings such as Australopithecus sediba and Homo haili in forms we have never dreamed before.
A breeze from the past: a skull of Sahelanthropus tchadensis
Below, the five most common ancestors of fossils are mentioned among others. Who knows, perhaps when more evidence is found, their stories change most things.
Sahelanthropus tchadensis : Was it a monkey?
About 7 million years old S. tchadensis is the oldest of all probable human beings in Africa so far. This type, officially known in Chad in 2001, contains only a very small number of fossils consisting of several teeth, fragments of two different subspecies, and most importantly, a relatively whole, one-piece skull
The features on the back of the skull indicate that this crawl is sitting on a vertical spine similar to a human being, indicating that S.tchadensis is walking upright. To make sure about this, more fossils are needed, especially from the leg area. Unconfirmed reports have reported that there is a thigh bone as well as a skull, but this finding has not yet been published in a scientific document. Only little evidence is available about it S.
tchadensis is still skeptical that it can be described as a human being rather than an ape species.
Orrorin tugenensis : Is there a connection between walking on two legs with the thigh bones?
In 2000, he discovered in the west of Kenya. Tugenensis is officially known as a dozen fossils of six teeth. Other fossils include a finger bone, two jaw pieces, pieces of three different femoral bones, and a piece from the upper arm bone. Many of the examinations were concentrated on one of the thigh bones. With this examination, He. Trying to determine whether tugenensis can walk on two legs like other human beings. At least this walk of the walk compliments many things. It is believed that more fossil recordings will attain certainty.
Between 1998 and 1999, the 3.3 million-year-old sediments of northwestern Kenya were brought to light K. platyops is best known for its skull, which is mostly entirely crushed and distorted. At the same time, it is said that there are several dozen pieces of fossils consisting of many teeth, fragments of a second skull, and several lower and upper jaw crests.
Up until now all K. Although the platyops belonged to the upper reaches of the fossils, there were also some very primitive stone tools on the same fossils later on. These instruments K. platyops but a researcher suggests that the maker of these instruments may be more or less a mysterious humanoid Australopithecus deyiremeda known only to a few chin pieces.
Homo rudolfensis : is it really a kind of person?
Most researchers believe that the human species emerged 2 to 3 million years ago in Africa, but no consensus has been reached about how many early human species share this land. Homo rudolfensis is at the very center of this dispute.
H. rudolfensis was known for many years only for its 1.9 million-year-old giant, flat-faced skull discovered in Kenya in 1972. In addition, three hundred and jawbone bones in Kenya, between 2007 and 2009, helped confirm that the skull in 1972 of some researchers really belonged to a different species, but A. sediba and H. Other researchers, including Lee Berger, who discovers continued to skeptical about the subject.
Even so, there is a dispute even in the name of the tide: this name was given in 1970 by a Russian researcher who was not involved in the discovery of the skull in 1972. The three fossil-analyzing researchers found later, H. rudolfensis says there is a need for more fossils to confirm whether the name is valid, or whether it can really be included in the human species
The Denisovals: the last and certainly the least
In terms of fossil record, Denisovals are least known among all human beings. Up to now, there are only four small fossils, three of which are found to belong to them, all 50,000 to 225,000 years old, and one finger bone.
All four fossils from Siberia's Denisova cave contain enough DNA to confirm that they belong to the same genetic pool. This gene pool is different from the two other known human beings in Nebraska, Neanderthals and our species, gene pools in Eurasia over the last few decades. Between 2007 and 2014, two ancient human skulls found in China are said to belong to Denisovalla, but if DNA can not be obtained from these skulls, it is unlikely that we are sure of that.
