?Are Neanderthals considered ancestors of humans
The Nobel Prize in Medicine and Physiology for Science 2022 went to the Swedish scientist Svante Pääbo, one of the most important figures of the Max Planck Institute in the field of evolutionary biology.
25 hours of cooking time is the virtuous gesture of Neanderthal man, one of the ancient ancestors of humans, and of Kardin 40,000 years ago.
“Svante Pääbo” is a Swedish geneticist, born on April 20, 1955. He specializes in the field of evolutionary genetics. He has worked on this task with his team for 25 years. If we enter the website of the German Max Planck Institute located in the German city of Leipzig, we will find that he is the head of the Evolution Department. Human

But are Neanderthals really considered human ancestors?
Since the Neanderthal was a contemporary of Homo sapiens, and some of its members interbred with us, and was even skilled at making jewelry, boats, and cooking, and used tools similar to those we used, why is it classified as an independent species and not just an ordinary race like the rest of the human races?
?What is the definition of type
A species is a group of individuals that share a single gene pool and can intermarry and produce fertile offspring and new individuals. This is the classic definition of a species, which is correct, but it is old and not comprehensive. The definition of a species varies according to usage. Neanderthals and Homo sapiens are of the same species, but they are not of a single species. .
Initially, the volume of the skull of Homo sapiens is 1,350 cubic centimetres, while the volume of the skull of Neanderthal man is 1,500 cubic centimetres. The base of the skull of modern humans is circular in shape. The skull of his Neanderthal counterpart has a linear downward curvature, the frontal square is your name. That is, the skull of the Neanderthal type was larger, but the rate of consciousness and intelligence of Homo sapiens and its brain was more complex than the brain of "Neanderthals."
The Neanderthal's structure and body are stronger and larger than the body of modern humans. This is due to the difficult and arduous nature of their lives, as it is scientifically proven that they hunted cats and large animals such as woolly mammoths, lions, and tigers. The center of gravity of the Neanderthal's strength is located 2.5 centimeters below the navel. They also had 3 points in the middle ear that helped them hear better.
Two out of 100% of Europeans currently have Neanderthal caveman genes in their DNA, and the fewest people carrying his genes are Africans, while evidence says that Homo sapiens appeared to me for the first time on the continent of Africa, especially in the eastern Horn of Africa region, and this explains why. We find most of its skulls and skeletons there, and then it began to spread to various parts of the world.
?Dimension ratio and genetic distance
The proportion of distance and genetic difference between all human races, meaning an Indian, Chinese, African, European, or American person
The percentage of genetic difference between them does not exceed 0.1%, while the percentage of genetic difference between modern humans and Neanderthals reaches 0.3%. Although it seems a small percentage, it has a huge impact. You can refute the existence of something called Neanderthals by proving that there is a human race with a genetic distance between it and the rest of the races. To 0.3%, adding that the differences found above will not be found in any human race existing at the present time.
Neanderthals did not live at the time of the discovery of agriculture 12,000 years ago, nor did they live at the time of the emergence of religious rituals 11,000 years ago, or the time of the emergence of civilization and empires 10,000 years ago, or the time of the invention of writing 5,000 years ago.
All of these morphological, anatomical, and genetic differences and differences make Neanderthal classified as an independent species in its own right, not just an ordinary human race as some claim, and not a branch of man.
The most important differences between Neanderthals and Homo sapiens can be summarized:
The size of the Neanderthal skull would be about 1,500 cubic centimetres. Easy, give us the skull of the current human being of this size. The current human has a skull volume of 1,300 cubic centimetres.
There are three pieces of bone present in the middle ear of Neanderthals, which you will find different anatomically and formally from their counterparts in the anatomical ear of current humans.
The scapula is broad and richly muscled in Neanderthals.
The joints of Neanderthals' arms were stronger and wider than those of modern humans
Tibia tibia is shorter in Neanderthals.
There is an important anatomical piece on the Neanderthal forehead called the Brow Ridge.
Note: Neanderthals are not classified as hominids, but rather among the ancestors of humans, because there is confusion between the term “humanoids” and “human ancestors.” Hominids are a term applied exclusively to another human race called Australopithecus.
