Breaking News: January 7th, 2014: Earliest dental caries in hunter-gatherers population in North Africa

TAF_caries

A team of researchers including Abdeljalil Bouzouggar, co-director of excavations and associated scientist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, report the earliest evidence of tooth decay in ancient hunter-gatherers in a population from Taforalt Cave, Morocco, in a paper published in PNAS. The study was conducted on 52 adult dentitions dated to between 15,000 and 13,700 years ago, and 51% of the teeth show caries, a disease thought to be related to agricultural societies but which can now be extended further back in time hundreds years. Taforalt populations were harvesting sweet acorns and pine nuts with fermentable carbohydrates that gave rise to this high percentage of caries. This change in society, which is usually linked to the emergence of farming, was embedded in earlier forager societies.

August 12, 2013: Neandertals made the first specialized bone tools in Europe

New finds demonstrate: Neandertals were the first in Europe to make standardized and specialized bone tools - which are still in use today

Lissoir

Two research teams from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, and the University of Leiden in the Netherlands have jointly reported the discovery of Neandertal bone tools coming from their excavations at two neighboring Paleolithic sites in southwest France. The tools are unlike any others previously found in Neandertal sites, but they are similar to a tool type well known from later modern human sites and still in use today by high-end leather workers. This tool, called a lissoir or smoother, is shaped from deer ribs and has a polished tip that, when pushed against a hide, creates softer, burnished and more water resistant leather. The bone tool is still used today by leather workers some 50 thousand years after the Neandertals and the first anatomically modern humans in Europe.

Neanderthals meet Homo sapiens

New high precision radiocarbon dates of bone collagen show that a cultural exchange may have taken place between modern humans and Neanderthals more than 40,000 years ago.

It has long been debated whether the Châtelperronian (CP), a transitional industry from central and southwestern France and northern Spain, was manufactured by Neanderthals or modern humans. An international team of researchers led by Jean-Jacques Hublin of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, has now analyzed bone samples from two sites in France, Grotte du Renne and Saint Césaire, and radiocarbon-dated them using an accelerator mass spectrometer. The new high precision dates show that the CP bone tools and body ornaments were produced by Neanderthals. However since these late Neanderthals only manufactured CP body ornaments after modern humans arrived in neighboring regions, the study suggests that cultural diffusion might have taken place between modern humans and Neanderthals.

New Kenyan Fossils Shed Light on the Evolution of the Genus Homo

Exciting new fossils discovered east of Lake Turkana confirm that there were two additional species of our genus – Homo – living alongside our direct human ancestral species, Homo erectus, almost two million years ago. The finds, announced in the prestigious scientific journal Nature on August 9th, include a face, a remarkably complete lower jaw, and part of a second lower jaw. They were uncovered between 2007 and 2009 by the Koobi Fora Research Project (KFRP), led by Meave and Louise Leakey. KFRP member Fred Spoor of the Department of Human Evolution at the Max Planck Institute for Evolutionary Anthropology in Leipzig coordinated the scientific study of the fossils. Most of the analyses were performed in Leipzig, including virtual reconstruction of the new finds using sophisticated computer technology.

Inaugural Meeting "European Society for the study of Human Evolution", Leipzig, 23-24 September, 2011

Humankind has always been fascinated by the question of where we come from. Historically this quest for our evolutionary origins started in 19th century Europe with the discovery of Neanderthal fossils in several countries. Despite this long research tradition there has never been a Europe-wide forum supporting and promoting the study of human evolution. In Leipzig, 23-24 September, 2011, this will now change with the formal inauguration of ESHE, the "European Society for the study of Human Evolution", and its first international scientific conference. ESHE will promote research into human biological and cultural evolution by stimulating communication and cooperation between scientists and by raising public awareness and understanding.

As part of the ESHE meeting there will be a free public lecture on Friday evening 23 September by Professor Svante Pääbo of the Max Planck Institute for Evolutionary Anthropology in Leipzig on "Exploring the Genomes of Archaic Humans". The lecture will be held at 19:00 at the University of Leipzig, Universitätsstraße 3, Hörsaalgebäude, Lecture Hall 9.

The host of this year's meeting is the Max Planck Institute for Evolutionary Anthropology.

Handier than homo habilis?

The versatile hand of Australopithecus sediba makes a better candidate for an early tool-making hominin than the hand of Homo habilis. Hand bones from a single individual with a clear taxonomic affiliation are scarce in the hominin fossil record, which has hampered understanding of the evolution of manipulative abilities in hominins. An international team of researchers including Tracy Kivell of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany has now published a study that describes the earliest, most complete fossil hominin hand post-dating the appearance of stone tools in the archaeological record, the hand of a 1.98-million-year-old Australopithecus sediba from Malapa, South Africa. The researchers found that Au. sediba used its hand for arboreal locomotion but was also capable of human-like precision grips, a prerequisite for tool-making. Furthermore, the Au. sediba hand makes a better candidate for an early tool-making hominin hand than the Homo habilis hand, and may well have been a predecessor from which the later Homo hand evolved.

Early hominin landscape use

So far ranging and residence patterns amongst early hominins have been indirectly inferred from morphology, stone tool sourcing, comparison to living primates and phylogenetic models. An international team of researchers including Sandi Copeland, Vaughan Grimes and Michael Richards of the Max Planck Institute for Evolutionary Anthropology in Leipzig/Germany have now investigated landscape use in Australopithecus africanus (with fossils from sites dating between 2.8-2.0 million years ago) and Paranthropus robustus (with fossils from sites dating between 1.9-1.4 million years ago) from the Sterkfontein and Swartkrans cave sites in South Africa using strontium isotope analysis. This method helps identify the geological substrate on which an animal lived during tooth mineralization. (Nature, June 2nd, 2011)

The brains of Neanderthals and modern humans developed differently

A new study by the Max Planck Institute for Evolutionary Anthropology in Leipzig published in Current Biology documents species differences in the pattern of brain development after birth that are likely to contribute to cognitive differences between modern humans and Neanderthals. Whether cognitive differences exist between modern humans and Neanderthals is the subject of contentious disputes in anthropology and archaeology. Because their brain size ranges overlap, many researchers previously assumed that the cognitive capabilities of these two species were similar. Among humans, however, the internal organization of the brain is more important for cognitive abilities than its absolute size is. The brain’s internal organization depends on the tempo and mode of brain development. Based on detailed measurements of internal shape changes of the braincase during individual growth, a team of scientists from the MPI has shown differences in the patterns of brain development between humans and Neanderthals during a critical phase for cognitive development.

afarensis tool useIn January of 2009, the Dikika Research Project, working in the Afar region of Ethiopia and led by Zeresenay Alemseged of the California Academy of Sciences, discovered two bones with cut and percussion marks that show that human ancestors were using stone tools and consuming the meat and marrow of large mammals nearly 1 million years earlier than previously documented. The bones date to roughly 3.4 million years ago and provide the first evidence that Lucy’s species, Australopithecus afarensis, used stone tools and consumed meat. Both of the marked bones came from large mammals. One fossil is a rib fragment, the other a femur shaft fragment. Both are marred by multiple cut, scrape, and percussion marks. These finds were published in the August 12, 2010, issue of the journal Nature.

The origin of Neandertals

Western Eurasia yielded a rich Middle (MP) and Late Pleistocene (LP) fossil record documenting the evolution of the Neandertals that can be analyzed in light of recently acquired paleogenetical data, an abundance of archeological evidence, and a well-known environmental context. Their origin likely relates to an episode of recolonization of Western Eurasia by hominins of African origin carrying the Acheulean technology into Europe around 600 ka. An enhancement of both glacial and interglacial phases may have played a crucial role in this event, as well as in the subsequent evolutionary history of the Western Eurasian populations. In addition to climatic adaptations and an increase in encephalization, genetic drift seems to have played a major role in their evolution. To date, a clear speciation event is not documented, and the most likely scenario for the fixation of Neandertal characteristics seems to be an accretion of features along the second half of the MP. Although a separation time for the African and Eurasian populations is difficult to determine, it certainly predates OIS 11 as phenotypic Neandertal features are documented as far back as and possibly before this time. It is proposed to use the term "Homo rhodesiensis" to designate the large-brained hominins ancestral to H. sapiens in Africa and at the root of the Neandertals in Europe, and to use the term "Homo neanderthalensis" to designate all of the specimens carrying derived metrical or non-metrical features used in the definition of the LP Neandertals.

The origins of modern human diversity

The interpretation of genetic evidence regarding modern human origins depends, among other things, on assessments of the structure and the variation of ancient populations. In our morphometric study we find that the early modern group has more shape variation than any other group in our sample, which covers 1.8 million years, and that they are morphologically similar to recent modern humans of diverse geographically dispersed populations but not to archaic groups. Of the currently competing models of modern human origins, some are inconsistent with these findings. Rather than a single out-of-Africa dispersal scenario, we suggest that early modern humans were already divided into different populations in Pleistocene Africa, after which there followed a complex migration pattern.

"You will give birth in pain": Neandertals too

book coverThe virtual reconstruction of a Neandertal woman's birth canal reveals insights into the evolution of human childbirth

Researchers from the University of California at Davis (USA) and the Max Planck Institute for Evolutionary Anthropology in Leipzig (Germany) present a virtual reconstruction of a female Neanderthal pelvis from Tabun (Israel). Although the size of Tabun's reconstructed birth canal shows that Neanderthal childbirth was about as difficult as in present-day humans, the shape indicates that Neanderthals retained a more primitive birth mechanism than modern humans. The virtual reconstruction of the pelvis from Tabun is going to be the first of its kind to be available for download on the internet for everone interested in the evolution of humankind (PNAS, April 20th, 2009).
