In Reaching for the Sun, William Wellman explores modern man’s enslavement by his own inventions

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.

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.

There is evidence that Neanderthals deliberately buried their dead and occasionally even marked their graves with offerings, such as flowers. No other primates , and no earlier human species , had ever practiced this sophisticated and symbolic behavior. DNA has been recovered from more than a dozen Neanderthal fossils, all from Europe; the Neanderthal Genome Project is one of the exciting new areas of human origins research.

Neanderthal 1 was the first specimen to be recognized as an early human fossil. When it was discovered in in Germany, scientists had never seen a specimen like it: the oval shaped skull with a low, receding forehead and distinct browridges, the thick, strong bones. In , it became the first fossil hominin species to be named. Several years after Neanderthal 1 was discovered, scientists realized that prior fossil discoveries—in at Engis, Belgium, and in at Forbes Quarry, Gibraltar—were also Neanderthals.

But scientists are constantly in the field and the laboratory, excavating new areas and conducting analyses with groundbreaking technology, continually filling in some of the gaps about our understanding of human evolution. Below are some of the still unanswered questions about H.

European early modern humans

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.

The only thing to do was run.

A great number of these cannot be assigned to the modern human species, Homo evolutionary sequence leading from ape-like forms to modern humans. Distinctive bones of the oldest species of the human genus, Homo, date back to.

Human Evolution S tudies in evolutionary biology have led to the conclusion that human beings arose from ancestral primates. This association was hotly debated among scientists in Darwin’s day. But today there is no significant scientific doubt about the close evolutionary relationships among all primates, including humans. Many of the most important advances in paleontology over the past century relate to the evolutionary history of humans.

Not one but many connecting links–intermediate between and along various branches of the human family tree–have been found as fossils. These linking fossils occur in geological deposits of intermediate age. They document the time and rate at which primate and human evolution occurred. Scientists have unearthed thousands of fossil specimens representing members of the human family.

Comparisons of DNA sequences between Neandertals and present-day humans have shown that Neandertals share more genetic variants with non-Africans than with Africans. This could be due to interbreeding between Neandertals and modern humans when the two groups met subsequent to the emergence of modern humans outside Africa.

However, it could also be due to population structure that antedates the origin of Neandertal ancestors in Africa. We measure the extent of linkage disequilibrium LD in the genomes of present-day Europeans and find that the last gene flow from Neandertals or their relatives into Europeans likely occurred 37,—86, years before the present BP , and most likely 47,—65, years ago.

This supports the recent interbreeding hypothesis and suggests that interbreeding may have occurred when modern humans carrying Upper Paleolithic technologies encountered Neandertals as they expanded out of Africa. One of the key discoveries from the analysis of the Neandertal genome is that Neandertals share more genetic variants with non-Africans than with Africans. This observation is consistent with two hypotheses: interbreeding between Neandertals and modern humans after modern humans emerged out of Africa or population structure in the ancestors of Neandertals and modern humans.

These hypotheses make different predictions about the date of last gene exchange between the ancestors of Neandertals and modern non-Africans. We estimate this date by measuring the extent of linkage disequilibrium LD in the genomes of present-day Europeans and find that the last gene flow from Neandertals into Europeans likely occurred 37,—86, years before the present BP , and most likely 47,—65, years ago. This supports the recent interbreeding hypothesis and suggests that interbreeding occurred when modern humans carrying Upper Paleolithic technologies encountered Neandertals as they expanded out of Africa.

Homo Erectus: Facts About the ‘Upright Man’

Genomic studies reveal how convoluted the emergence of modern humans was. Humans today are mosaics, our genomes rich tapestries of interwoven ancestries. With every fossil discovered, with every DNA analysis performed, the story gets more complex: We, the sole survivors of the genus Homo , harbor genetic fragments from other closely related but long-extinct lineages. Modern humans are the products of a sprawling history of shifts and dispersals, separations and reunions — a history characterized by far more diversity, movement and mixture than seemed imaginable a mere decade ago.

The events that do get pinned down therefore tend to be relatively recent, starting with the migration of modern humans out of Africa 60, years ago, during which they interacted with hominin relatives like the Neanderthals and Denisovans they met along the way. Evidence of interbreeding during any migrations before then, or during events that transpired earlier within Africa, has been elusive.

As scientists peer further back in time and uncover evolutionary relationships in unprecedented detail, their findings are complicating the narrative of human history and rescuing some formerly missing chapters from obscurity.

Adam Driver, the Original Man

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.

They were given the name “Cro-Magnon” because, in , parts of five skeletons were discovered in a rock shelter of that name, located in the famous Dordogne Valley of France. In the 19th century, scientists compared these skeletons to Neanderthal skeletons that had been found earlier in similarly dated sites like Paviland, Wales and a little later at Combe Capelle and Laugerie-Basse in France.

They decided that the findings were different enough from the Neanderthals—and from us—to give them a different name. A century and a half of research since then has led scholars to change their minds. The new belief is that the physical dimensions of the so-called “Cro-Magnon” are not sufficiently different enough from modern humans to warrant a separate designation.

Instead, scientists today use “Anatomically Modern Human” AMH or “Early Modern Human” EMH to designate the Upper Paleolithic human beings who looked a lot like us but did not have the complete suite of modern human behaviors or rather, who were in the process of developing those behaviors. Another reason for the change is that the term “Cro-Magnon” doesn’t refer to a particular taxonomy or even a particular group located in a particular place.

When Humans Became Human

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.

Correlating cultural, technological and ecological aspects of both Upper Pleistocene modern humans UPMHs and Neandertals provides a useful approach for achieving robust predictions about what makes us human.

Here we present ecological information for a period of special relevance in human evolution, the time of replacement of Neandertals by modern humans during the Late Pleistocene in Europe. We demonstrate that their diet was essentially similar, relying on the same terrestrial herbivores, whereas mobility strategies indicate considerable differences between Neandertal groups, as well as in comparison to UPMHs.

Our results indicate that UPMHs exploited their environment to a greater extent than Neandertals and support the hypothesis that UPMHs had a substantial impact not only on the population dynamics of large mammals but also on the whole structure of the ecosystem since their initial arrival in Europe. Nowadays modern humans Homo sapiens are the only species of humans left on Earth. Relatively soon after the arrival of UPMHs in this region about 45—43, years ago, the Neandertals became extinct 1 , 2 , 3 , 4.

Differences in the ecological niches of UPMHs and Neandertals while coexisting in the same ecosystems are regularly suggested as being the possible cause for the demise of Neandertals. According to this hypothesis, UPMHs had a broader dietary ecological spectrum, especially having possibly included more aquatic resources than that of Neandertals.

How China Is Rewriting the Book on Human Origins

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.
