Protein Residue Found on Hominin Stone Tools

first_imgWould you expect pieces of meat to survive on flakes of rock in the desert for 250,000 years?Modern humans are typically dated from 200,000 years ago to the present, according to the evolutionary timeline. Stone tools found in Jordan from “human-like species” older than moderns still have identifiable protein remains of the animals the hunters slaughtered with the tools, according to a press release from the University of Victoria:How smart were human-like species of the Stone Age? New research published in the Journal of Archaeological Science by a team led by paleoanthropologist April Nowell of the University of Victoria reveals surprisingly sophisticated adaptations by early humans living 250,000 years ago in a former oasis near Azraq, Jordan.The research team from UVic and partner universities in the US and Jordan (see backgrounder for list of co-authors) has found the oldest evidence of protein residue—the residual remains of butchered animals including horse, rhinoceros, wild cattle and duck—on stone tools. The discovery draws startling conclusions about how these early humans subsisted in a very demanding habitat, thousands of years before Homo sapiens first evolved in Africa.This announcement makes “startling” claims that should question the validity of the dates. What were “surprisingly sophisticated” early humans doing in Jordan, if the ancestors of modern humans were waiting to evolve in Africa? More importantly, how could protein residues remain in a “demanding habitat” for 250,000 years? Wouldn’t all traces of meat have been eliminated completely by bacteria and natural decay? Photos in the press release show workers digging near to the surface.The summary of the paper in the Journal of Archaeological Science says that the finding “Expands [the] growing body of data on long-term survivability of biological materials.” The press release indicates how many tools were tested:The team excavated 10,000 stone tools over three years from what is now a desert in the northwest of Jordan, but was once a wetland that became increasingly arid habitat 250,000 years ago. The team closely examined 7,000 of these tools, including scrapers, flakes, projectile points and hand axes (commonly known as the “Swiss army knife” of the Paleolithic period), with 44 subsequently selected as candidates for testing. Of this sample, 17 tools tested positive for protein residue, i.e. blood and other animal products.It doesn’t mean that thousands of the other tools lacked residues. It only means that of the 44 they decided to test with immunoelectrophoresis, 17 of them (38%) still had animal proteins on them. If the tools were left in a wetland that dried out (“one of the last humid refugia in NE Jordan”), it’s hard to believe any traces of meat would remain at all. But the researchers seem more impressed by the intelligence of the hunters.Based on lithic, faunal, paleoenvironmental and protein residue data, we conclude that Late Pleistocene hominins were able to subsist in extreme arid environments through a reliance on surprisingly human-like adaptations including a broadened subsistence base, modified tool kit and strategies for predator avoidance and carcass protection.The types of planning and thinking evident on the tools “significantly diverges from what we might expect from this extinct species,” the article says. So if they are surprised by unexpected wisdom of the ancients, why should neutral observers believe what they say about the age of the tools? Why should the hunters be called “hominins” instead of talented people?It’s looking like the hunters were wiser than their gullible descendants who cannot, for the life of them, question the long ages taught to them by the Darwinian storytellers.

Ohio State’s Rattan Lal receives international agriculture award

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Rattan Lal, Distinguished University Professor of Soil Science at The Ohio State University, yesterday (Oct. 28) received the 2018 World Agriculture Prize from the Global Confederation of Higher Education Associations for Agricultural and Life Sciences (GCHERA). His work focuses on the ability of soil to address such global challenges as climate change, food security and water quality.The award honors Lal’s “exceptional and significant lifetime achievements” in the agricultural and life sciences, GCHERA officials said. It was presented in a ceremony at China’s Nanjing Agricultural University.Lal is a faculty member in Ohio State’s School of Environment and Natural Resources (SENR), part of the College of Food, Agricultural, and Environmental Sciences (CFAES). He is the director of CFAES’s Carbon Management and Sequestration Center (CMSC), conducts research with support from the college’s Ohio Agricultural Research and Development Center, is an adjunct professor with the University of Iceland, and is the current president of the Vienna-based 60,000-member International Union of Soil Sciences.The prize carries with it a cash award of $100,000, which Lal said he will donate to an endowment being developed to provide long-term support to the CMSC. Lal founded the center in 2000.In presenting the award, GCHERA President John Kennelly said Lal is “globally recognized for his contributions to education and research in the sustainable management of world soils.”Specifically, Kennelly said, Lal’s contributions have focused on two areas: managing the physical, hydrological and mechanical properties of soil to minimize the risks of soil degradation and to sustain food production; and restoring degraded and desertified soils by sequestering atmospheric carbon dioxide in soil and vegetation to adapt to and mitigate climate change.Sequestering, or “locking up,” atmospheric carbon dioxide in the soil, according to a U.S. Geological Survey website, is “one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change.”“Lal’s mentorship of hundreds of students who have gone on to hold leadership positions in academia, government and industry ensures that his legacy will continue for many decades through the work of his students,” said Kennelly, a professor of agricultural, life and environmental sciences at Canada’s University of Alberta.“He has worked for 50 years to enhance the prestige of the agriculture profession in general and that of soil science in particular,” Kennelly said. “His membership on scientific boards and advisory panels, and the many fellowships that he has been awarded, testify to his international status.“Being the current president of the International Union of Soil Science, he is the global ambassador of soil science and agriculture.”last_img read more

first_imgPay TV subscribers are highly likely to churn in the absence of premium sports rights being part of their service, according to a UK survey by Broadband Genie.According to the survey, 57% of pay TV customers who expressed an opinion, said that sports channels were a strong influence on deciding on a pay TV package, and 78% said the would consider switching or cancelling their contract if their pay TV provider “lost the rights to broadcast certain sports”.Some 61% of the 2,275 consumer surveyed said they currently had a pay TV package. Of those who expressed an opinion, 80% said their TV package provided quality content, but only 43% said it provided good value for money.Among consumers without pay TV, of those who responded, 29% said they had a subscription service within the past five years. Some 52% said they didn’t currently have a pay TV service because it was too expensive, with 26% saying they were satisfied with Freeview and 12% saying they preferred to use streaming services.last_img read more

BIRMINGHAM Ala AP – A Democratic candidate for

first_imgBIRMINGHAM, Ala. (AP) – A Democratic candidate for Alabama governor says the arrest of a campaign worker accused of violating the state’s sex offender registration and notification act was “politically motivated.”Sue Bell Cobb said she accepted Paul Littlejohn III’s resignation Friday. Littlejohn was her campaign’s Jefferson County field director.As a registered sex offender, he’s charged with working too close to a school or daycare through his work at a church and failing to update his employment status.Cobb says the warrant was issued after she publicly defended Littlejohn’s character. She says the Jefferson County Sheriff’s Office is led by a Republican, indicating Republicans don’t want to face her in the general election.Chief Deputy Randy Christian said Cobb wanted law enforcement “to just look the other way.”___(Copyright 2018 The Associated Press.
