Humans were present in the Philippine islands as early as 700,000 years ago

An international team of prehistorians led by Dr Thomas Ingicco from the Museum National d’Histoire Naturelle, France, and M. Clyde Shago, from the National Museum of the Philippines discovered the oldest evidences for the peopling of the Philippines by Hominins. Dated to 709,000 years old, the archaeological site of Kalinga (Rizal Municipality, Kalinga Province, Luzon Island) is described in a publication in Nature journal on march 2

All along the Quaternary era (since 2.6 Million years ago), the Philippines have always formed a string of islands isolated from mainland Southeast Asia by deep sea straits. The oldest human presence in the Philippines up to now was 67,000 years old by Homo aff. sapiens (2010). The Kalinga site, excavated since 2014 and dated to 709,000 years by several physico-chemical methods (Electro-spin resonance, disequilibrium in the argon family and in the uranium family, palaeomagnetism), proves that the first colonization was actually ten times older, dating back to the early Middle Pleistocene about 800,000 years before present.

The archaeological excavation has delivered several animal remains among which are the monitor lizard, the box turtle, the Philippine brown deer, the Stegodon (a cousin of the elephant) and the rhinoceros which is now extinct in the Philippines since at least 100,000 years. For this latter species, Rhinoceros philippinensis, an almost complete individual was recovered in association with tens of prehistoric stone tools made on anvil. The rhino carcass further shows several butchery marks such as cut marks on the ribs and on the foot bones, and percussion marks to break the arm bones allowing extraction of the marrow. All these archaeological findings are so many indirect proofs for a very old presence of early humans also known as Hominins on the island of Luzon.

The way of arrival of this fauna and these Hominins on the islands at these old times is still under question. While herbivores are known to be excellent long distance swimmers and could have arrived that way to the Philippines during one of the low sea level period, such a hypothesis is impossible for humans. Did another species than Homo sapiens ever mastered sailing skills or was this colonization accidental thanks to natural rafts such as floating mangrove that typhoons occasionally break off, a rare but well documented phenomenon?

The archaeological investigations of the Kalinga site were mainly funded by the French Department for Foreign Affairs, the National Museum of the Philippines, the University of the Philippines and the National Geographic Society.

There will be 23 sessions and more than 140 presentations in these conferences. They are focused on young non-doctors researches in archaeology and its related disciplines. The scientific results from their work will be presented and the actual situation of the archaeological discipline will be discussing along with others aspects such the archaeological heritage, its socialization and divulgation, the professional archaeology, gender archaeology, the interdisciplinary in archaeological research, social hierarchy, residential and funerary archaeology, epigraphy, restoration and conservation and the evolution of the landscape and wildlife in archaeology.

The last conferences took place in Burgos, June 2017. During this 10th edition it was noticed that the young archaeology in the Iberian Peninsula seems to be more alive than ever. An example of it is that the assistance for the last editions has been more than 120 young archaeologists coming from Spain, Portugal, Italy, France and South America.

These conferences are also sponsored by the Ajuntament de Tarragona, Tarragona Turisme, Beta Analytic, Strati-Arqueogal, CIEMAD and the Asssociació Catalana de Bioarqueologia (ACBA).

 

John Charles Willman, new Marie Curie researcher at IPHES to study the use of “teeth-as-tools”

The chronological focus, between 9,000 and 3,000 years ago, provides an ideal case study given the extensive socioeconomic reorganization that is attributable to the transition from foraging to food production including increases in social stratification and task specialization

John Charles Willman, originally from the United States where he obtained his Ph.D.  in Anthropology at Washington University in Saint Louis, recently joined the research staff at IPHES (Institut Català de Paleoecologia Humana i Evolució Social) funded through a Marie Skłodowska-Curie Individual Fellowship (H2020-MSCA-IF-2016) awarded by the European Research Council. The fellowship funds postdoctoral research on the IDENTITIES project (Integrative Approaches to Dental Wear: Non-Masticatory Tooth-Use Across the Mesolithic-Neolithic Transition Among Iberian Foraging and Farming Societies), focusing on the cultural use of “teeth-as-tools”.

John will conduct postdoctoral research on the IDENTITIES project over the course of two years at IPHES. His research focuses on human dental wear related to the non-masticatory use of the dentition, or the use of “teeth-as-tools”, among human groups from Mesolithic, Neolithic, Copper and Bronze Age contexts across the Iberian Peninsula. Ultimately, the data generated will address how biocultural changes in non-masticatory tooth-use reflect changing social identities across archaeological groups. The chronological focus (~9,000-3,000 BP) provides an ideal case study given the extensive socioeconomic reorganization that is attributable to the transition from foraging to food production including increases in social stratification and task specialization.

A further research aim within the IDENTITIES project is to establish an integrative methodology to document non-masticatory dental wear. This will be accomplished with an interdisciplinary approach that brings together experts in microscopy, experimental methods, bio/archaeology, and paleoanthropology. Methods include recent advances in Gigapixel-like imaging strategies, confocal and scanning electron microscopy, and three-dimensional dental topographic methods to analyze experimentally-worn and bioarchaeological samples. A further benefit, and goal, of the integrative methodology is to cross-validate existing methodologies and advance the study of surface modification in bio/archaeology, paleoanthropology, and allied fields.

 

IPHES is inspired by the Smithsonian Natural History Museum to apply innovative conservation techniques to the fossils of large mammals found in the Barranc de la Boella site

catalàespañol

The conservation of the fossils recovered in archeopaleontological sites is an accurate work that demands specialized techniques. In order to improve the conservation of the 1 million year-old large mammals remains from the Barranc de la Boella site (Tarragona, Spain), Lucía López-Polín, conservator at IPHES (the Institut Català de Paleoecologia Humana i Evolució Social) has benefit from fellowship grant to conduct her research at the at the National Museum of Natural History in Washington DC.

The aim of this research was to study the packaging and storage systems for fossil vertebrates that are used in the above-mentioned Smithsonian museum. The study seek to assess if their methods would be useful for the fossils of proboscides and other large mammals from Barranc de la Boella, which have a unique problem due to their large dimensions and weights.

The work has been developed in the Conservation department headed by Catharine Hawks who is in charge of the conservation of the museum’s enormous collections. There, Lucía López-Polin has reviewed the different packaging systems of fossil vertebrates and she also carried out a series of quantitative analyzes on the protection that different packaging systems provide to the fossils. The experimental work that has been carried out along with Steven Jabo, preparator at the  Paleobiology department.

Biographical profile

Lucía López-Polín is a conservator-restorer specialized in the treatment of quaternary remains. Member of the Atapuerca Research Team since 1997, she joined the scientific team led by Eudald Carbonell at the Universitat Rovira i Virgili as a fellow in 2003. Since 2008 she has been a conservator at IPHES. She is an expert in field work and in the treatment of archaeopaleontological material from Paleolithic sites up to 1 million.

This recognition of excellence is an opportunity to establish a comprehensive and coherent Human Resources Strategy, that should allow to achieve international visibility by providing favorable working environment for research with equal opportunities, ethical integrity and work life balance.

Our Human Resources Strategy for Researchers Action Plan (HRS4R Action Plan) was drawn up by a working group in a participative and open process involving this the representatives of the whole IPHES research areas through a general survey. The 2016- 2020 Action Plan comprises actions related to 4 pillars: ethical and professional aspects, recruitment, working conditions and Social Security, and training.

The preferred use of the right hand is more ancient than it was thought and it is an ancestral characteristic of first hominins

It was considered that Neandertals were the first species with well-defined handedness, but a new international research led by IPHES goes back it to the first Homo species, Homo habilis.

Homo sapiens are considered to be the only species with a predominance of a preferred use of the right hand, with a ratio of 9 right-handed to 1 left-handed people. However, when did the human handedness appeared in human evolution remains unknown. An international research recently published and led by Marina Lozano, researcher at IPHES (Institut Català de Paleoecologia Humana i Evolució Social), shows that this behaviour is more ancient than it was thought. At population level, Neandertal as far as 130,000 years ago, showed a well-stablished hand preference as our species. Nevertheless, this practice goes back to Homo habilis showing that handedness is an ancestral characteristic of our genus.

The scientific community has developed a huge amount of studies focused on handedness and brain laterality in hominins. However, in this work, a large sample has been analyzed, for the first time, following the same methodology. That is 120 individuals of five different human species (Homo habilis, Homo antecessor, preneandertals, European Neandertals and Homo sapiens), spanning almost 2 million years.

The main research teams focused on the study of handedness in fossil hominins are involved in this work. So, this is the result of an international collaboration between researchers of Spain, USA and Italy. Thanks to this work “we can affirm that the trend to have a preferred hand is an intrinsic characteristic of our genus. The handedness was established slowly in each of the species who precede us. From this research, we can do some inferences because handedness implies brain laterality that is closely related to language”, mentions the researcher Marina Lozano.

This international team studied the cultural dental wear, specifically the striations (cut marks) that result from the use of the mouth as a third hand, when some material is held between the anterior teeth and cut with a lithic tool. These marks are analyzed with environmental scanning electron microscopy.
