The prehistory of the Iberian Peninsula begins with the arrival of the first hominins 1. In this long period, some of its most significant landmarks were to host the last stand of the Neanderthal people, to develop some of the most impressive Paleolithic art, alongside southern France , to be the seat of the earliest civilizations of Western Europe and finally to become a most desired colonial objective due to its strategic position and its many mineral riches.
Hominin inhabitation of the Iberian Peninsula dates from the Paleolithic. Significant evidence of an extended occupation of Iberia by Neanderthal man has also been discovered. Homo sapiens first entered Iberia towards the end of the Paleolithic. For a time Neanderthals and modern humans coexisted until the former were finally driven to extinction.

It is taken to include fossils from throughout the Last Glacial Maximum LGM , covering the period of about 48, to 15, years ago 48—15 ka , spanning the Bohunician , Aurignacian , Gravettian , Solutrean and Magdalenian periods. Gregory proposed the subspecies name Homo sapiens cro-magnonensis. In literature published since the late s, the term EEMH is generally preferred over the common name Cro-Magnon, which has no formal taxonomic status, as “it refers neither to a species or subspecies nor to an archaeological phase or culture”.
The description as “modern” is used as contrasting with the ” archaic ” Homo heidelbergensis and Homo neanderthalensis , who lived within Europe during about ka to 37 ka, and who with the arrival of EEMH became extinct or absorbed into their lineage. These mesolithic hunter-gatherers emerge after the end of the LGM c. There appear to have been multiple modern human Homo sapiens immigration and disappearance events on the European continent, whereupon they interacted with the indigenous Neanderthals H.

Few shoes impacted my life as much as the Double Monk Strap. In fact, they are the inspiration behind my foray into shoemaking with The Noble Shoe. Researching the rich history behind certain styles or leathers is a rabbit hole. There is so much, or so little information that makes it such an engrossing experience. It allows you to fully understand the reasoning behind their creation but also find the kind of personal style you seek.
So with Autumn in full swing may I suggest you grab a cup of warm coffee and join me as we dive deep into the History of Monk Strap Shoes! What makes Monk Straps unique is not just their looks but also their origin. Most of the shoes today have roots in royalty or the military. Chukka Boots and Derbies make fine examples of this.
Tracing the exact date of this style of shoe is impossible. It is safer to say however that it made its appearance somewhere around the Middle Ages — AD. There is an urban legend circulating around the web that an English Gentleman visited a monastery in the Swiss Alps and brought the design back with him to London.
European early modern humans
Louis, MO Author contributions: M. We report here on the direct isotopic evidence for Neanderthal and early modern human diets in Europe. The isotopic evidence indicates that in all cases Neanderthals were top-level carnivores and obtained all, or most, of their dietary protein from large herbivores.

A much debated ancient human skull from Mongolia has been dated and genetically analysed, showing that it is the earliest modern human yet found in the region, according to new research from the University of Oxford. The study published in Nature Communications used Radiocarbon dating and DNA analysis and revealed that the only Pleistocene hominin fossil discovered in Mongolia, initially called Mongolanthropus, is in reality a modern human who lived approximately 34 – 35 thousand years ago.
The skullcap, found in the Salkhit Valley northeast Mongolia is, to date, the only Pleistocene hominin fossil found in the country. The skullcap is mostly complete and includes the brow ridges and nasal bones. The presence of archaic or ancient features have led in the past to the specimen being linked with uncharacterized archaic hominin species, such as Homo erectus and Neanderthals. Previous research suggested ages for the specimen ranging from the Early Middle Pleistocene to the terminal Late Pleistocene.
The Oxford team re-dated the specimen to 34, — 33, years ago. This is around 8, years older than the initial radiocarbon dates obtained on the same specimen. To make this discovery, the Oxford team used a new optimised technique for radiocarbon dating of heavily contaminated bones. This method relies on extracting just one of the amino acids from the collagen present in the bone. Dating this amino acid allows for the drastic improvement in the removal of modern contaminants from the specimens.
Detroit, Reaching for the Sun follows Russ, a backwoods clam-digger who moves to Detroit to work in a car factory so he can afford an outboard motor for his boat. Read more from the series here. With the American economy recovering under the New Deal and workers getting back to the factories, it would seem that a more fundamental anxiety about the industrial age resurfaced in Hollywood cinema. Fordist production of the previous decades had vitiated the skilled workforce, reducing the factory employee to a tiny cog in the production machinery — an awareness that was heightened by the brief favour socialism enjoyed in the country in the late s.
The Paramount production Reaching for the Sun takes a less jovial route, exploring the theme within the framework of romantic comedy and marital drama.

Ramapithecus , fossil primate dating from the Middle and Late Miocene epochs about No significance was attached to those fossils until , when American anthropologist Elwyn Simons of Yale University began studying them and fit the jaw fragments together. On the basis of his observations of the shape of the jaw and of the morphology of the teeth—which he thought were transitional between those of apes and humans—Simons advanced the theory that Ramapithecus represented the first step in the evolutionary divergence of humans from the common hominoid stock that produced modern apes and humans.
The age of the fossils about 14 million years fit well with the then-prevailing notion that the ape-human split had occurred at least 15 million years ago. The first challenge to the theory came in the late s from American biochemist Allan Wilson and American anthropologist Vincent Sarich, who, at the University of California, Berkeley , had been comparing the molecular chemistry of albumins blood proteins among various animal species.
They concluded that the ape-human divergence must have occurred much later than Ramapithecus. It is now thought that the final split took place some 6 million to 8 million years ago. Finally, in , Pilbeam discovered a complete Ramapithecus jaw, not far from the initial fossil find, that had a distinctive V shape and thus differed markedly from the parabolic shape of the jaws of members of the human lineage.
He soon repudiated his belief in Ramapithecus as a human ancestor, and the theory was largely abandoned by the early s. Ramapithecus fossils subsequently were found to resemble those of the fossil primate genus Sivapithecus , which is now regarded as ancestral to the orangutan ; the belief also grew that Ramapithecus probably should be included in the Sivapithecus genus.
When Humans Became Human
When white phosphorus touches skin, it can burn through to the bone. As the particles ignite, they emit a garlic-like odor and melt everything in their path. Adam Driver, Marine lance corporal, 1st Battalion, 1st Marine Regiment, Weapons Company, 81st Platoon, was aware of these effects when he looked up at the California sky, during a drill exercise, one day in , and saw a cloud of white phosphorus exploding above his head.
Nowadays modern humans (Homo sapiens) are the only species of humans left of well-preserved faunal remains dating to the early UP in this region and Proceedings of the National Academy of Sciences of the United.
Freshwater fish are an important part of the diet of many peoples around the world, but it has been unclear when fish became an important part of the year-round diet for early humans. A new study by an international team of researchers, including Erik Trinkaus, Ph. Louis, shows it may have happened in China as far back as 40, years ago. Chemical analysis of the protein collagen, using ratios of the isotopes of nitrogen and sulfur in particular, can show whether such fish consumption was an occasional treat or a regular food item.
Michael Richards of the Max Planck Institute for Evolutionary Anthropology explains “Carbon and nitrogen isotope analysis of the human and associated faunal remains indicate a diet high in animal protein, and the high nitrogen isotope values suggest the consumption of freshwater fish. This analysis provides the first direct evidence for the substantial consumption of aquatic resources by early modern humans in China.
Since this occurs before there is consistent evidence for effective fishing gear, the shift to more fish in the diet likely reflects greater pressure from an expanding population at the time of modern human emergence across Eurasia.

Ancient Mongolian skull is the earliest modern human yet found in the region
Some defining features of their skulls include the large middle part of the face, angled cheek bones, and a huge nose for humidifying and warming cold, dry air. Their bodies were shorter and stockier than ours, another adaptation to living in cold environments. But their brains were just as large as ours and often larger – proportional to their brawnier bodies. Neanderthals made and used a diverse set of sophisticated tools, controlled fire, lived in shelters, made and wore clothing, were skilled hunters of large animals and also ate plant foods, and occasionally made symbolic or ornamental objects.

On the outskirts of Beijing, a small limestone mountain named Dragon Bone Hill rises above the surrounding sprawl. Along the northern side, a path leads up to some fenced-off caves that draw , visitors each year, from schoolchildren to grey-haired pensioners. It was here, in , that researchers discovered a nearly complete ancient skull that they determined was roughly half a million years old. Dubbed Peking Man, it was among the earliest human remains ever uncovered, and it helped to convince many researchers that humanity first evolved in Asia.
Since then, the central importance of Peking Man has faded. Although modern dating methods put the fossil even earlier — at up to , years old — the specimen has been eclipsed by discoveries in Africa that have yielded much older remains of ancient human relatives. But the tale of Peking Man has haunted generations of Chinese researchers, who have struggled to understand its relationship to modern humans.
Keen to get to the bottom of its people’s ancestry, China has in the past decade stepped up its efforts to uncover evidence of early humans across the country. It is reanalysing old fossil finds and pouring tens of millions of dollars a year into excavations. The investment comes at a time when palaeoanthropologists across the globe are starting to pay more attention to Asian fossils and how they relate to other early hominins — creatures that are more closely related to humans than to chimps.
On the biggest steps in early human evolution scientists are in agreement. The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs. They were flaking crude stone tools by 2. Then some of them spread from Africa into Asia and Europe after two million years ago. With somewhat less certainty, most scientists think that people who look like us — anatomically modern Homo sapiens — evolved by at least , years ago from ancestors who had remained in Africa.
Their brain had reached today’s size.

For besieged civilians, hope and safety lie underground inside the subterranean hospital known as the Cave, where pediatrician and managing physician Dr. Amani Ballour and her colleagues Samaher and Dr. Alaa have claimed their right to work as equals alongside their male counterparts, doing their jobs in a way that would be unthinkable in the oppressively patriarchal culture that exists above. Following the women as they contend with daily bombardments, chronic supply shortages and the ever-present threat of chemical attacks, The Cave paints a stirring portrait of courage, resilience and female solidarity.
A natural leader and problem solver, Dr. Amani Ballour was only 29 when her colleagues elected her to oversee the Cave in As director, Dr. Amani contended with the grave realities specific to running a hospital under siege conditions: finding solutions to equipment and medicine shortages; protecting the structure itself by adding aboveground and underground fortifications; and, above all, ensuring the safety of patients and staff.
