    The researchers trace the fossil record, which illustrates a timeline placing multiple species overlapping in time and geographic space. Their insights spur further questions about how these early human ancestors were related and shared resources... The 1974 discovery of Australopithecus afarensis, which lived from 3.8 to 2.9 million years ago, was a major milestone in paleoanthropology that pushed the record of hominins earlier than 3 million years ago and demonstrated the antiquity of human-like walking. Scientists have long argued that there was only one pre-human species at any given time before 3 million years ago that gave rise to another...

    ome 12,000 years ago, a teenage girl took a walk in what’s now the Yucatan Peninsula and fell 190 feet into a deep pit, breaking her pelvis and likely killing her instantly. Over time, the pit—part of an elaborate limestone cave system—became a watery grave as the most recent ice age ended, glaciers melted and sea levels rose. In 2007, cave divers happened upon her remarkably preserved remains, which form the oldest, most complete and genetically intact human skeleton in the New World. Her bones, according to new research published in Science, hold the key to a question that has...

    A smiling 3.2-million-year-old face greets visitors to the anthropology hall of the National Museum of Anthropology and History in Mexico City. This reconstruction of the famous Australopithecus afarensis specimen dubbed “Lucy” stands a mere 4 feet tall, is covered in dark hair, and displays a pleasant gaze. She’s no ordinary mannequin: Her skin looks like it could get goose bumps, and her frozen pose and expression make you wonder if she’ll start walking and talking at any moment. This hyper-realistic depiction of Lucy comes from the Atelier Daynès studio in Paris, home of French sculptor and painter Elisabeth Daynès. Her...

    New York (Reuters) - How can creatures as different in body and mind as present-day humans and their extinct Neanderthal cousins be 99.84 percent identical genetically? Four years after scientists discovered that the two species' genomes differ by a fraction of a percent, geneticists said on Thursday they have an explanation: the cellular equivalent of "on"/"off" switches that determine whether DNA is activated or not. :snip: Calling the work "pioneering," and "a remarkable breakthrough," paleoanthropologist Chris Stringer of the Natural History Museum in London said in an interview that the HOXD gene finding "may help to explain how these ancient...

    Past Horizons ^ | 3-9-2014
    The Mesolithic, a transitional period that lasted from circa 11,000 to 5,000 years ago (between the Palaeolithic and Neolithic), ends with the advent of agriculture and animal husbandry and the concurrent arrival of new genetic material from the Middle East. The arrival of the Neolithic farmers, with their carbohydrate-based and domesticated animal diet, along with food-borne pathogens and the inherent metabolic /immunological challenges can be reflected in genetic adaptations of post- Mesolithic populations.Pre-Neolithic genetic material The individual at the centre of the study belongs to a group prior to this influx of new genetic material.“The biggest surprise was to discover...

    Abstract The description of a new skull (D4500) from the Dmanisi site (Republic of Georgia) has reopened the debate about the morphological variability within the genus Homo. The new skull fits with a mandible (D2600) often referred as ‘big’ or ‘enigmatic’ because of its differences with the other Dmanisi mandibles (D211 and D2735). In this report we present a comparative study of the variability of the Dmanisi mandibles under a different perspective, as we focus in morphological aspects related to growth and development. We have followed the notion of modularity and phenotypic integration in order to understand the architectural differences...
  • 2 million years ago, human relative ‘Nutcracker Man’ lived on tiger nuts

    01/13/2014 3:35:18 PM PST · by Renfield · 46 replies
    An Oxford University study has concluded that our ancient ancestors who lived in East Africa between 2.4 million-1.4 million years ago survived mainly on a diet of tiger nuts. Tiger nuts are edible grass bulbs still eaten in parts of the world today. The study published in the journal, PLOS ONE, also suggests that these early hominins may have sought additional nourishment from fruits and invertebrates, like worms and grasshoppers. Study author Dr Gabriele Macho examined the diet of Paranthropus boisei, nicknamed “Nutcracker Man” because of his big flat molar teeth and powerful jaws, through studying modern-day baboons in Kenya....

    A dental study of 1,200 molars and premolars from 13 hominin species shows that no known species matches the expected profile of the last common ancestor of Homo neanderthalensis and anatomically modern Homo sapiens. The study, published online in the Proceedings of the National Academy of Sciences, also provides evidence that the lines that led to Neanderthals and modern humans diverged about 1 million years ago – much earlier than previous studies have suggested.“Our results call attention to the strong discrepancies between molecular and paleontological estimates of the divergence time between Neanderthals and modern humans. These discrepancies cannot be simply...

    The skeletal remains of an individual living in northern Italy 40,000-30,000 years ago are believed to be that of a human/Neanderthal hybrid, according to a paper in PLoS ONE. If further analysis proves the theory correct, the remains belonged to the first known such hybrid, providing direct evidence that humans and Neanderthals interbred. Prior genetic research determined the DNA of people with European and Asian ancestry is 1 to 4 percent Neanderthal. The present study focuses on the individual’s jaw, which was unearthed at a rock-shelter called Riparo di Mezzena in the Monti Lessini region of Italy. Both Neanderthals and...

    UA geneticists have discovered the oldest known genetic branch of the human Y chromosome – the hereditary factor determining male sex. The new divergent lineage, which was found in an individual who submitted his DNA to Family Tree DNA, a company specializing in DNA analysis to trace family roots, branched from the Y chromosome tree before the first appearance of anatomically modern humans in the fossil record. The results are published in the American Journal of Human Genetics. "Our analysis indicates this lineage diverged from previously known Y chromosomes about 338,000 ago, a time when anatomically modern humans had not...

    ScienceNordic ^ | 1-4-2013 | Tania Lousdal Jensen
    Analyses of Stone Age settlements reveal that the hunters were healthy and would gladly eat anything they could get their hands on, including carbohydrates – contrary to the modern definition of the Paleolithic, or Stone Age diet. The Stone Age hunter’s food contained large amounts of protein from fish, lean mean, herbs and coarse vegetables and has formed the basis of one of today’s hottest health trends: the paleo diet. The modern version of the Stone Age diet excludes foods rich in carbohydrates. This exclusion of carbs is based on the idea that Stone Age hunters didn’t have access to...

    Frontiers of Anthropology ^ | 12-16-2012 | Dale Drinnon
    The strong linkage between these populations has always been empirically apparent. This finally settles what has been obvious and clearly establishes the time line. Thus later incursions merely topped up an already European palette. What has been more troubling has been the avoidance of this topic from the academics. Now DNA research is systematically reducing sophism for what it truly is. Ignoring and even denying obvious evidence should be made into a capital crime in academe. It all starts with denigrating the technical abilities of our ancients by denying them the natural wits we are all born with. We...

    Skeletal remains in an island cave in Favignana, Italy, reveal that modern humans first settled in Sicily around the time of the last ice age and despite living on Mediterranean islands, ate little seafood. The research is published November 28 in the open access journal PLOS ONE by Marcello Mannino and colleagues from the Max Planck Institute for Evolutionary Anthropology, Germany. Genetic analysis of the bones discovered in caves on the Egadi islands provides some of the first mitochondrial DNA data available for early humans from the Mediterranean region, a crucial piece of evidence in ancestry analysis. This analysis reveals...

    A team of scientists has created what it believes is the first really accurate reconstruction of Neanderthal man, from a skeleton that was discovered in France over a century ago. In 1909, excavations at La Ferrassie cave in the Dordogne unearthed the remains of a group of Neanderthals. One of the skeletons in that group was that of an adult male, given the name La Ferrassie 1. These remains have helped scientists create a detailed reconstruction of our closest prehistoric relative for a new BBC series, Prehistoric Autopsy. La Ferrassie 1 is one of the most important discoveries made in...

    Neanderthals may have lived side by side with early humans and possibly interbred with them, according to new research. Stone axes and sharp flint arrowheads of both branches of the human race have been discovered in limestone caves in northern Israel. The findings, reported in the Times, have led archeologists to believe the two sub-species found harmony in a coastal mountain range that today is in a state of war with its neighbours...

    News out of France concerning Prehistoric cave drawings that were animated by torch-light is taking the art history world by storm, and has overwhelmed this artist to the point of awe. The cave drawings were found by archaeologist Marc Azema and French artist Florent Rivere, who suggest that Paleolithic artists who lived as long as 30,000 years ago used animation effects on cave walls, which explains the multiple heads and limbs on animals in the drawings. The images look superimposed until flickering torch-light is passed over them, giving them movement and creating a brief animation. “Lascaux is the cave with...

    Greece has been in the grip of a financial crisis for the last few years now and Greek heritage sites are hit the worst. There is however, an unseen, less well known crisis and it involves Greek palaeoanthropology -- the study of hominin evolution. It is not so much a crisis as a metaphorical drought of artefacts and fossil evidence, which remains the best way to understand human evolution in Greece. An understanding of tectonic activity and the ever changing relationship between the Aegean Sea and mainland Greece are crucial to understanding why so little Lower Palaeolithic Hominin material has...

    Right-handed humans vastly outnumber lefties by a ratio of about nine to one, and the same may have been true for Neanderthals. Researchers say right-hand dominance in the extinct species suggests that, like humans, they also had the capacity for language. A new analysis of the skeleton of a 20-something Neanderthal man confirms that he was a righty like most of his European caveman cousins whose remains have been studied by scientists (16 of 18 specimens). Dubbed "Regourdou," the skeleton was discovered in 1957 in France, not far from the famous network of caves at Lascaux....
