Top 10 Human Origins Discoveries in 2015

Top 10 Human Origins Discoveries in 2015

(Read the article on one page)

In 2015, DNA analysis provided deeper insight into the lives of our ancient ancestors. Studies of their appearance, diet, living conditions, and the human family tree, were all hot topics. Research suggesting new species and the concept of human de-evolution also made waves. Each of the following investigations into human origins demonstrate that human evolution is not as simple as many people think, and that technology is a tool that is of great advantage in advancing our knowledge of the past.

10. Neanderthals Had Hot Water and Bedrooms

Neanderthals Had Hot Water and Bedrooms

The living quarters of Neanderthals also made the news this year. Archaeologists in Spain made a number of discoveries inside an ancient cave in Abric Romaní, Catalonia which suggest that Neanderthals had hot water and separate living quarters around 60,000 years ago. The finding adds to the mounting evidence that Neanderthals were a lot more sophisticated than previously thought and were at least as advanced, if not more so, than early Homo sapiens.

More than 10,000 fossil remains and artifacts were retrieved from the cave, enabling scientists to confirm long-term occupation of the site by Neanderthals. Among the more significant discoveries was a concave hole, which was found enclosed by a large number of hearths with evidence of fire use. Archaeologists believe the Neanderthals used the hole to heat water by placing heated stones from the hearth. Archaeologists also determined that Neanderthals used different parts of the cave for different activities, including making tools, butchering meat and preparing food, throwing out rubbish, and sleeping.

9. Jawbone Found in Ethiopia Set to Rewrite History

Jawbone Found in Ethiopia Set to Rewrite History

A fossilized lower jaw, with five small teeth, began to connect the dots between primitive ancestors and modern humans. The specimen, discovered in Ethiopia, is the bone of one of the very first humans and comes from a time when humans split from the more ape-like ancestors, Australopithecus. The find is more than 400,000 years older than the oldest fossils belonging to the early humans who eventually gave rise to Homo sapiens, our modern species.

Field work is being done in the Ledi-Geraru site to see if more fossils can be recovered. More information could help determine if the jaw belongs to a known early species of Homo, or an entirely new species, and researchers are putting off definitively naming it for the time being.

8. Waves of Invaders Came to Britain but Left Few Genes

Waves of Invaders Came to Britain but Left Few Genes

People who came from prehistoric Germany, Belgium and France beginning about 11,000 years ago seem to have contributed the most genetic material to modern Caucasian Britons, according to a new study. People may have gone to the islands from those areas long ago via a land bridge. Also, some came from what is now France by boat.

The genetic study analyzed genes of 2,039 white people from England, Scotland, Wales and Northern Ireland. The results show their dominant ancestry pre-dates the most recent invaders – the Anglo-Saxons, Vikings, Normans and Romans. But of those four, the group that contributed the most genes was the Anglo-Saxons, who invaded in the fifth century AD.

As for the distribution of genes: The Orkney Islands are the only area where the people have significant Viking ancestry, with about 25 percent of the Orkney people’s genes being Viking. The modern people of Wales most closely hew genetically to Stone Age peoples. A bit less than half of modern Britons have Anglo-Saxon ancestry, most of whom are in England proper.

7. 50,000-year-old Skull May Show Human-Neanderthal Hybrids Originated in Levant, not Europe

50,000-year-old Skull May Show Human-Neanderthal Hybrids Originated in Levant, not Europe

In a third study on Neanderthals, a 55,000-year-old skull found at Manot Cave in northern Israel may be the earliest evidence of modern man meeting and mating with Neanderthals found to date. The partial skull “provides evidence that both modern humans and Neanderthals inhabited the southern Levant during the late Pleistocene, close in time to the likely interbreeding event between modern humans and Neanderthals.” This challenges the theory that two species connected 10,000 years later in Europe.

6. White Skin Developed in Europe Only as Recently as 8,000 Years Ago

A recent analysis by anthropologists suggests that the light skin color and the tallness associated with European genetics are relatively recent traits to the continent. The evidence suggests modern Europeans do not appear as their ancient ancestors did. Their study was based on 83 human samples from Holocene Europe and shows that for the majority of the time that humans have lived in Europe, the people had dark skin, and the genes signifying light skin only appear within the past 8,000 years. This recent and relatively quick process of natural selection suggests to researchers that the traits which spread rapidly were advantageous within that environment – especially those necessary for Vitamin D absorption. People in less sunny climates required different skin pigmentations in order to absorb and synthesize Vitamin D. Thus, pale skin was advantageous in the region.

FINALLY SOLVED : https://evolutionofhumanintelligence.wordpress.com/
The human evolution must perform the evolution of intelligence, but I have found only "the evolution of emotions". These three processes intersect at one point - baby / human infant that is incapable for independent survival for many years. That is not an evolutionary mistake, on the contrary, that is the key element. By observing his mother’s behavior, a process called MSP/multi self-projection passively occurs in baby’s brain when child perceives guardians body as his own. That way infant’s CNS immediately learns the shortest way to get something done which enables the creation of many more similar thinking processes till the moment when a minimal number of thinking processes are required in order to effect of self-consciousness arise.
To connect all this with a huge number of scientific data (Denisovans, Homo naledi, Scientific Adam, Mitochondrial Eve, autism, speech, pleasure in the presence of fire, dreams...) required membership in the Mensa organization... The biggest picture ( the framework ) for all scientific data ( even A.I. because start, origin of original, in making AI is crucial / what has been missing) is FEST theory.

Could the loss of DNA over the years be contributed to the way humans control their environment, for example if a human gives natural birth it is usually done in a hospital. An animal can give. Birth usually without the help of anyone else. And humans also have trouble eating raw meat compared to domesticated pets.

Human Origins

Noah's Sacrifice - watercolor circa 1896–1902 by James Tissot
The imperfect state of archaeological researches in the Near East impedes any definite identification of the original race or races that created the earliest civilizations of Mesopotamia and Egypt. According to Gordon Childe, however, the predominant racial element in the earliest graves in the region from Elam to the Danube is the ‘Mediterranean’.

Ancient Places

Himmerod Abbey and Church building
Himmerod Abbey, a Cistercian monastery that's existed for almost 900 years in what is now western Germany is closing down for good, due to running expenses and also a shortage of monks. Notably, the monastery was used during the 1950’s in a distinctly non-monastic capacity, as a secret meeting point of former Wehrmacht high-ranking officers discussing West Germany's rearmament.

Opinion

The ancient and mysterious Sphinx, Giza, Egypt.
In 1995, NBC televised a prime-time documentary hosted by actor Charlton Heston and directed by Bill Cote, called Mystery of the Sphinx. The program centered on the research and writings of John Anthony West, a (non-academic) Egyptologist, who, along with Dr. Robert Schoch, a professor of Geology at Boston University, made an astounding discovery on the Great Sphinx of Giza in Egypt.

Our Mission

At Ancient Origins, we believe that one of the most important fields of knowledge we can pursue as human beings is our beginnings. And while some people may seem content with the story as it stands, our view is that there exists countless mysteries, scientific anomalies and surprising artifacts that have yet to be discovered and explained.

The goal of Ancient Origins is to highlight recent archaeological discoveries, peer-reviewed academic research and evidence, as well as offering alternative viewpoints and explanations of science, archaeology, mythology, religion and history around the globe.

We’re the only Pop Archaeology site combining scientific research with out-of-the-box perspectives.

By bringing together top experts and authors, this archaeology website explores lost civilizations, examines sacred writings, tours ancient places, investigates ancient discoveries and questions mysterious happenings. Our open community is dedicated to digging into the origins of our species on planet earth, and question wherever the discoveries might take us. We seek to retell the story of our beginnings.
