Anthropologists at the University of Tennessee conducted an original study and found that the shape of the American head is changing. What this is connected with is still unclear, but it is quite obvious that the skulls of white Americans have become larger, taller and narrower, and their faces, accordingly, have narrowed and extended in height. It is possible that this also applies to the rest of the world's population. Big head, short legs, long body
- it is according to this scenario that the human skeleton changes
The study was conducted by scientists from the Department of Forensic Anthropology at the University of Tennessee, Knoxville: Coordinator of Forensic Anthropology Lee Jantzprofessor emeritus Richard Jantz and associate professor Joan Devlin … Scientists studied 1,500 American skulls from the mid-1800s to the mid-1980s, and found a strange phenomenon: the average height from the base to the top of the skull in men increased by 8 millimeters, the volume of the skull increased by 200 cubic centimeters - almost from tennis ball. For women, the corresponding increase was 7 millimeters and 180 cubic centimeters. As a result, the skull has grown by an impressive 6.8% since the late 1800s, while body height has increased by 5.6% and thigh length has only increased by 2%.
Researchers cannot pinpoint the exact reasons for the changes in the shape of the head of the Americans. It is not yet clear whether this is due to evolutionary changes or a change in lifestyle, which in modern people is very different from that of their ancestors. Scientists speculate that this is the result of a change in growth patterns through improved nutrition, reduced infant and maternal mortality, less manual labor, and the elimination of old ethical barriers to marriage. But scientists do not yet know which of the reasons are of paramount importance.
The researchers also found that humans began to mature physically earlier. In particular, this was reflected in the early closure of a special area of the skull called sphenoid-occipital synchondrosis. Previously, it was covered with cartilage at the age of about 20 years, and now much earlier - at 14 years old for girls and 16 for boys.
The studies were conducted only with European Americans, as the scientists had the largest sample bank for this group. However, it is possible that changes in the skeleton are also taking place in other regions of the planet, which means that this trend is common for all mankind. The changes are going pretty quickly and make you think about what many science fiction writers have drawn, describing sedentary people of the future as creatures with a disproportionately large head, short legs, long torso and arms. It is interesting that many "contactees with aliens" describe just such creatures, and some ufologists consider them guests from the future.

Elongated Skulls From Paracas Have An Unusual Mutation In Their DNA
In 1928, on the southern coast of Peru, in the Paracas Desert, archaeologist Julio Tello made a startling find. The researcher discovered a huge burial ground with a complex structure, where lay the most unusual remains that scientists have ever seen: the skulls of the deceased were not only unusually large, but also had an unusual elongated shape. In total, Tello discovered more than three hundred skulls, the age of which was estimated at about three thousand years. For the analysis of their DNA, the researchers took
500-year-old Grave With Elongated Skulls Of Noble People Found In Bolivia
Bolivian archaeologists said they found a 500-year-old mass grave with over a hundred skeletons and artifacts. Some remains had artificially deformed elongated skulls, which most likely belonged to rich and noble people. In South America, elongated skulls are mainly found in Peru, so the Bolivian find immediately interested many. However, archaeologists are deliberately hiding the place where they found the grave in order to save it from looting. It is only indicated that ss

Among the citizens of the United States, a subculture called the Preppers is gaining popularity. These people are actively preparing for the end of the world: stocking up on essentials, equipping shelters and upgrading their cars.
