New species of ancient human found in a Philippine cave

first_imgFrom a cave on the island of Luzon in the Philippines, researchers have unearthed fossils dating back more than 50,000 years ago, which they say belong to a new species of early human, now dubbed Homo luzonensis.H. luzonensis has a mix of ancient and modern traits: Most of its teeth are small and simple in shape, resembling those of modern humans, while its finger and toe bones have features similar to Australopithecus, ancestors of humans who are known to have last walked in Africa around 2 million years ago.The researchers involved in the current study are confident that H. luzonensis will hold up as a new species because its skeletal and dental elements “have no equivalents anywhere amongst the known Homo lineage.” Over the past decade, archaeologists have dug out several pieces of bones and teeth from a cave on the island of Luzon in the Philippines. These fossil remains, all estimated to be at least 50,000 years old, belong to a new species of early human, researchers have now confirmed in a study published in Nature.The journey to discovering this early human species, dubbed Homo luzonensis, has been a long one.Archaeologist Armand Mijares, an associate professor at the University of the Philippines and co-lead author of the study, first began excavating around Callao Cave on Luzon in 2003, when his team unearthed evidence of human activity dating back some 25,000 years. He returned to the cave in 2007, this time digging much deeper than he had the first time. At depths of around 8 to 9 feet (2.4 to 2.7 meters), among bones of deer and other animals, his team discovered a foot bone.The team sent the bone to Philip Piper, a professor at the Australian National University, who soon confirmed what Mijares suspected: the bone belonged to a human.“When Dr. Armand Mijares (Project Leader) and I found the first human bone dating to more than 50,000 years ago at Callao in 2007, we knew [what] we had was something special,” Piper, co-author of the study, told Mongabay in an email. “We didn’t know it was a new species then of course, but we did know that we had the oldest human remains in the Philippines. From then on in it has been a case of building up the evidence.”Five teeth belonging to Homo luzonensis.

These remains belong to at least two adults and one juvenile, the researchers say.Florent Détroit, a paleoanthropologist at France’s Musée de l’Homme and co-lead author of the study, and his colleagues then meticulously compared the fossils with all known species of our genus Homo, ultimately concluding that the fossils pointed to a Homo species that was new to science.H. luzonensis has a mix of ancient and modern features, the researchers say. Most of its teeth, small in size and relatively simple in shape, resemble those of modern humans — the small teeth also suggest that H. luzonensis could have been small-bodied — but its finger and toe bones have features similar to Australopithecus, ancestors of humans who are known to have last walked in Africa around 2 million years ago. It is this combination of unique dental and skeletal traits that makes H. luzonensis stand out, Piper said.A number of experts not involved in the study agree that the combination of features uncovered by Mijares and colleagues is unique and points to a new Homo species. Archaeologist Adam Brumm, an associate professor at Griffith University, Australia, for instance, told National Geographic that the finding was “truly sensational.”“The discovery team has done a very meticulous and commendable job describing these new fossils, and their naming of a new species, in my opinion, is valid,” Brumm said.Philip Piper inspecting the cast of a foot bone discovered by Armand Mijares in 2007. Image by Lannon Harley.A few experts, such as Huw Groucutt of the Max Planck Institute for Chemical Ecology, are not entirely convinced. While agreeing that the fossils do paint a convincing picture of a new human species, Groucutt told The New York Times that drawing conclusions from a few bones could be “risky.”The researchers involved in the current study, however, are confident that H. luzonensis will hold up as a new species. “The skeletal and dental elements recovered have no equivalents anywhere amongst the known Homo lineage,” Piper said.“Added to the meticulously analysed anthropological data we need to take into consideration the concepts of Island Biogeography,” he added. “Luzon Island is, and undoubtedly has been in the past, a biodiversity hotspot. [It’s] an isolated island — animals arrive there, become isolated and over time evolutionary adaptation leads to divergence from the ancestors. Something like 90% of the non-flying mammals (excludes bats) of Luzon are endemic, that is, they are found on Luzon and no where else in the world, not even on other Philippine islands. Why shouldn’t we expect the same for any hominin species that became isolated on Luzon?”Callao Cave in Luzon Island, in the Philippines, where the fossils of Homo luzonensis were discovered. Image courtesy of Callao Cave Archaeology Project.Mijares and Piper’s studies are not the only evidence of hominins or early humans in the Philippines. In 2018, another group of researchers published a study describing the bones of a butchered rhinoceros and stone tools they had discovered on Luzon, dating back some 700,000 years. Whether the tools were the handiwork of ancestors of Homo luzonensis or not is unclear, but it does suggest that early human species occupied Luzon between 700,000 and 50,000 years ago.Taken together, the discovery of both H. luzonensis on Luzon, and the tiny early human species H. floresiensis from the island of Flores in neighboring Indonesia in 2004, raises several questions about who the ancestors of these early humans were and how they dispersed across Asia. The findings also underscore the prominence of Asia in weaving together the story of human evolution.“This is a very exciting discovery, with unexpected age constraints and features,” Shanti Pappu, an archaeologist with the India-based Sharma Centre for Heritage Education who was not involved in the study, told Mongabay. “These discoveries point to how little we know of the story of human evolution and associated archaeology in Asia, and leave room open for more debates. India too has a wealth of new information coming out from recent studies of prehistoric sites, and along with other recent discoveries new perspectives on the Asian Palaeolithic are emerging.”Piper added that the discovery of a new species in the Philippines showed that “there is much more to learn and considerably more to be unearthed.”“Due to the numerous island archipelagos that make up Island Southeast Asia east of Wallace’s Line, and the potential to reach islands and become isolated, the region has the potential to become one of the real hotspots for understanding hominin evolutionary history,” he said.Citation:Détroit, F., Mijares, A.

Good effort trying to be objective in this article. I would like to give a constructive feedback which could help in clearing things up.1. It is mentioned that planting trees in village common lands will have negative affects socially and ecologically. There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsored Archeology, Biogeography, Environment, Evolution, Happy-upbeat Environmental, Human Migration, Islands, New Species, Research, Science, Species Discovery center_img Article published by Shreya Dasguptalast_img read more

Inauguration preparations in full swing

first_img20 May 2014 Preparations are in full swing for Jacob Zuma’s inauguration as South African President on Saturday. The event is expected to draw thousands of people, including numerous current and former heads of state, to the Nelson Mandela Amphitheatre at the Union Buildings in Pretoria. “Government has thus far received confirmations from 26 heads of state and 11 prime ministers and/or vice-presidents,” acting Government Communication and Information System CEO Phumla Williams told journalists in Pretoria on Monday. “This equates to a total of 37 heads of state and government who will attend. Also in attendance will be four former heads of state, 14 eminent persons and 118 foreign ambassadors resident in South Africa.” Regarding the budget allocation, Williams said expenditure would be less than what had been spent on previous inaugurations. Performance Monitoring and Evaluation Minister Collins Chabane said last week that the inauguration had been budgeted for within various government departments. “Departments have been encouraged to cut out any expenses that can be avoided, so as to be sensitive to the austerity measures applied throughout government,” Williams said. “Accountability in this regard will follow the normal accounting procedures.”Saturday’s proceeedings Williams said the government encouraged all South Africans to be part of the occasion, adding that those who could not attend would be able to follow proceedings on television and radio, or at 47 public viewing areas in the provinces. Saturday’s proceeedings will start with invited guests and members of the public arriving at the Nelson Mandela Amphitheatre and the Southern Lawns at the Union Buildings from as early as 8am. There will be no private vehicle access to the Union Buildings or the area immediately surrounding the venue. Instead, there will be a park-and-ride facility for members of the public at the Tshwane Events Centre, and a park-and-ride facility for invited guests and VIPs at Rietondale Park on Soutpansberg Road. People living in the vicinity of the Union Buildings and the Bryntirion area will be asked to present their municipal accounts at traffic control points. “Even though the event is taking place on a weekend, Tshwane Metro Police will enforce the road closures and motorists are kindly requested to adhere to the arrangements made for this day,” Williams said. Members of the public attending the event are advised that no alcohol, drugs, firearms, weapons, bottles or cans will be allowed. Source: SAnews.gov.zalast_img read more

SA, Botswana to upgrade border posts, bridges

first_img8 July 2014 South Africa and Botswana have signed a memorandum of agreement that will see the two countries improving cooperation to promote increased cross-border trade, economic growth and regional integration. Key to the agreement is a programme to upgrade bridges and border posts connecting the two countries, starting with the reconstruction of the Rammotswa Bridge, which crosses the Notwane River where it borders South Africa and Botswana. Speaking to journalists in Pretoria on Monday after signing the agreement, Transport Minister Dipuo Peters said preliminary designs for the new bridge had been completed, and that South Africa had already committed R20-million to the project. She added that the South African National Roads Agency had a dedicated project manager managing the process on the ground. “Key to our agreement is that it will enhance regional integration as well as economic development,” Peters said. “It will also enhance the free movement of people across our two countries.” Botswana Transport and Communications Minister Nonofo Molefhi said: “As South Africa is an economic hub in the region, it remains an attractive trade partner for most of our products and services. “The road and bridges project will go a long way in terms of strengthening regional integration, as envisioned in the Southern African Development Community (SADC) protocols.” Reconstruction of the Rammotswa Bridge will pave the way for the upgrade of the Swartkopfontein border post, which currently has to close for long periods over the rainy season, when the existing concrete drift river crossing is submerged. Swartkopfontein offers a potentially convenient commercial route between Zeerust in South Africa and Gaborone, Lobatse and Ramotswa in Botswana. The border post is ideally positioned between the commercial border posts of Kopfontein and Ramatlabama, and will relieve the pressure of traffic on these border posts once it becomes usable on a regular basis.

Will the Invincible Buckeyes Team from OSU and OSC Prove to be Invincible?

first_imgMike Bernhardt is the Community Evangelist for Intel’s Technical Computing GroupKaren Tomko, Scientific Applications Group Manager at the Ohio Supercomputer Center (OSC), has assembled a team of fellow Buckeyes to attempt the Intel Parallel Universe Computing Challenge (PUCC)Opens in a new window at SC14 in November.We asked Karen a few questions about her team, called the Invincible Buckeyes (IB), and their proposed participation in the PUCC. The 2014 Invincible Buckeyes (IB) team includes (from l to r) Khaled Hamidouche, a post-doctoral researcher at The Ohio State University (OSU); Raghunath Raja, Ph.D student (CS) at OSU; team captain Karen Tomko; and Akshay Venkatesh, Ph.D student (CS) at OSU. Not pictured is Hari Subramoni, a senior research associate at OSUQ: What was the most exciting thing about last year’s PUCC?A: Taking a piece of code from sequential to running in parallel on the Xeon Phi in 15 minutes, in a very close performance battle against the Illinois team was a lot of fun.Q: How will your team prepare for this year’s challenge?A: We’ll do our homework for the trivia, brush up on the parallel constructs, look at some Fortran codes, and make sure we have at least one vi user on the team.Q: What would you suggest to other teams who are considering participation?A: First I’d say, if you are considering it then sign up. It’s a fun break from the many obligations and talks at SC. When you’re in a match don’t over think, the time goes very quick. Also, watch out for the ‘Invincible Buckeyes’!Q: SC14 is using the theme “HPC Matters” for the conference. Can you explain why “HPC Matters” to you?A: HPC systems allow scientists and engineers to tackle grand challenge problems in their respective domains and make significant contributions to their fields. It has enabled innumerous discoveries in the fields of astro-physics, earthquake analysis, weather prediction, nanoscience modeling, multi-scale and multi-physics modeling, biological computations, and computational fluid dynamics, to name a few. Being able to contribute directly/indirectly to these discoveries by means of the research we do matters a lot to our team.last_img read more
