Discovering hafted spear points half a million years old is like finding iPods at a Roman archaeological site, a paleoanthropologist said.Half a million years ago, Neanderthals had not evolved yet, according to evolutionary anthropology. There was only Heidelberg Man and “the last common ancestor of Neandertals and modern humans,” PhysOrg said. National Geographic quoted John Shea saying this is “like finding an iPod in a Roman Empire site. It’s that level of weirdness.”There is some doubt about the dating, but the news articles are quoting the paper in Science (Nov 16) with some confidence, where Wilkins et al., claimed, “Multiple lines of evidence indicate that ~500,000-year-old stone points from the archaeological site” in South Africa they excavated “functioned as spear tips.”If true, this nearly doubles the age for this kind of technology. National Geographic wrote, “If the dating is correct, it suggests our evolutionary forebears mastered the art of the stone-tipped spear half a million years ago—some 250,000 years earlier than previously thought.”Putting a rock tip on a spear involves multiple mental and physical skills. “To fasten a handle to a blade—a technique called hafting—a prehistoric hunter likely would have had to procure a stone blade, a wooden shaft, twine woven from plants or animal sinew, and glue made from tree resin. The glue itself may have required a mastery of fire, to liquefy the resin, said Shea, of New York’s Stony Brook University.”The hafting process requires forethought. “You have to plan days in advance before actually being able to use your weapons to hunt,” [Jayne Wilkins, lead author] said. And you’d want to teach your comrades to do the same, presumably by talking.So this find hints at language, too, as well as manual dexterity, mastery of fire, forethought and a large brain. Shea thinks there is no question the skill involved speech. “We have language, and Neanderthals likely had language … so it stands to reason that our last common ancestor had linguistic abilities too,” he said. But that begs the question of when language emerged from ancestors lacking it.“At least one thing seems sure: Strapping a blade to a stick helped make us who we are today, according to Arizona State University anthropologist Curtis Marean.” Some evolutionists propose that access to meat led to the expansion of the human brain (examples on Live Science #1, #2). But why did that work for humans, and not lions and other carnivores? What difference does it make if meat is cooked or not? Does your dog get smarter by eating cooked meat scraps from the table? Even if it did, how could it pass on that trait by Darwinian and not Lamarckian processes?At Live Science, Marean said, “These people were like you and I.” But that comment was for an earlier find putting similar technology at 90,000 years ago, reported Nov 7. “Every time we excavate a new site in coastal South Africa with advanced field techniques, we discover new and surprising results that push back in time the evidence for uniquely human behaviors,” Marean said. “Now evidence has been pushed back to half a million years.”Prior to the spear-points story, Live Science had published an article highlighting evidence from stone tools that suggests that humans sailed to Mediterranean islands far earlier than expected – 170,000 years ago or more, not just 9,000 years. This would suggest that Neanderthals or other pre-modern humans were seafaring people, capable of constructing boats as well as making tools. The surprise from South Africa makes one wonder if it’s only a matter of time before scientists find sailing evidence even farther back in time.The news from the South African cave adds to the evidence that humans have always been humans, regardless of the artificial categories evolutionary anthropologists pigeonhole them in. Only their collective technology has improved, not their bodies and brains.The evolutionary story of early man is unraveling. It is no longer plausible to suppose that dumb brutes hundreds of thousands of years ago were grunting their way up to modernity. Who can believe that these masterful hunters were too stupid to ride a horse and plant a farm? With the fall of evolution’s colossal tale the evolutionary dating methods collapse, too. Ditch the myth now so you won’t look so stupid later when a future, more enlightened consensus calls a halt to the storytelling. There were no iPods in Rome, and there was no half million years of human evolution.(Visited 13 times, 1 visits today)FacebookTwitterPinterestSave分享0
18 March 2016Anant Singh, widely acknowledged as South Africa’s pre-eminent film producer behind popular favourites such as Sarafina!, Mandela: Long Walk to Freedom and the Leon Schuster films, received the first Lionel Ngakane Lifetime Achievement Award from the RapidLion Film Festival on 15 March 2016.The award recognises Singh’s contribution to the advancement of the South African and African film industries.The RapidLion Festival, founded by actor and director Eric Myeni, is a new film showcase event held in Johannesburg. It highlights not only a collection of feature films, short films and documentaries made in Africa, but includes contributions from the country’s BRICS partners, Brazil, Russia, China and India. It runs at The Market Theatre until 19 March.The festival’s local highlight is Kalushi, a film based on the life of Solomon Mahlangu, which will end the event.The lifetime achievement award is named after legendary South African actor and filmmaker Lionel Ngakane. Ngakane was best known for his role in the original 1956 version of Cry, the Beloved Country and his independent short film Jemima & Johnny about the 1958 Notting Hill race riots in London.Ngakane lived in exile for most of his life, starring in many international film and television productions. He returned to South Africa in 1994 to retire, and died in 2003, shortly after he was awarded the South African Order of Ikhamanga in Silver for outstanding achievement in the field of movie-making and contribution to the development of the film industry in South Africa and on the continent.The first film version of Cry the Beloved Country was shot in 1951 with Dr. Lionel Ngakane.

It is also a special privilege for me to have received the award tonight at The Market Theatre, the place where Sarafina! was born, and in the year that The Market celebrates its 40th anniversary.”Singh’s latest project is the death penalty drama set in South Africa, Shepherds and Butchers, starring British actor Steve Coogan.Source: Screen Africa
Share Facebook Twitter Google + LinkedIn Pinterest By Todd NeeleyDTN Staff ReporterOMAHA (DTN) — Environmentalists and some other groups often accuse agriculture producers of being part of the problem when it comes to climate change. But farmers and ranchers testifying before the U.S. Senate Agriculture Committee on Tuesday told senators they are trying to be part of the solution.Weston, Nebraska, farmer Matt Rezac told the committee, although the industry isn’t perfect, farmers are doing what they can to sustainably produce crops.“I get frustrated about the misconception of farmers blindly dumping chemicals all over their farms, because it’s just not the case,” he said. “Not only do we care deeply for the health of our farms, in this farm economy you can’t afford to be inefficient and waste inputs. I also know there is room for improvement. But farmers are often stubborn. Farmers tend to be followers, following what your dad did and often falling into the trap of, ‘Well, that’s how we’ve always done it.’”Kansas rancher Debbie Lyons-Blythe said ranchers need to be credited for the work they do when it comes to climate-change mitigation.Lyons-Blythe told the committee the industry continues to be concerned government regulation will make business challenging for farmers and ranchers.“Climate-change policies that unfairly target cattle producers fail to recognize the positive role of cattle and beef in a healthy, sustainable food system and misguided policies can threaten the viability of our industry,” she said.“Threats from urban encroachment, natural disasters and government overreach impact our industry, too, and keep us from putting land stewardship into practice,” Lyons-Blythe said. “Ranching has several positive effects beyond just the health of the soil and flora. Several species of wildlife, from large ungulates to small pollinators, benefit from the open spaces which working ranches provide.”ZERO EMISSIONSThe proposed Green New Deal has called for eliminating all emissions from cattle as part of a national strategy to control methane emissions.Frank Mitloehner, professor in the department of animal science at the University of California, Davis, told the committee animal agriculture has been targeted for its greenhouse gas emissions but the data shows the livestock industry is a small emitter. He said all livestock production in the United States accounts for only about 3.9% of all GHG emissions.Former U.S. Secretary of Agriculture Tom Vilsack told the committee future climate-change mitigation strategies offer economic opportunities for agriculture.Vilsack, the current president and CEO of the U.S. Dairy Council, talked about Newtrient LLC, a company established by the 12 largest milk cooperatives.The company, which includes nearly 20,000 dairy farmers, launched a new initiative called the Net Zero Project, Vilsack said. It is designed to find technology to achieve zero emissions and improve water quality in the industry.Part of the project includes a demonstration farm initiative to identify a set of technologies and management practices that may be used by dairies across the country.“The goal is not to find a single, transformational technology,” Vilsack said. “The goal is to highlight entire suites of practices and technologies, which are available to and economically viable for farms of varying sizes and geographies.”Some solutions, he said, will be applicable only to small farms. Others will only be achievable with the scale of larger operations. Many will be size neutral, such as improved genetics or feed management.“Our aspirational goal for net-zero emissions will not be achieved by every farm individually, but rather by the collective efforts of all farms, cooperatives and processors,” Vilsack said.ON-FARM SOLUTIONSRezac, who operates a 2,500-acre corn and soybean farm that has been in the family for nearly 140 years, said he realized decades ago his farm will have to find ways of becoming more sustainable and profitable at the same time.While no-till farming is popular as a way to conserve the soil, Rezac said those kinds of practices opened the door for his future.“First thing I noticed was that we had a serious soil-compaction problem on the farm and that once we started really concentrating on the soil, we saw that soil come back to life,” he said. “Instead of just treating the symptoms of poor soil health, we diagnosed the root cause and the world opened up.”Rezac’s farm uses both variable-rate fertilizer technology and moisture probes to manage water. In addition, he said taking tissue samples throughout the growing season allows him to make nutrient adjustments in-season.“Most people don’t understand this, but giving a plant too much of a certain nutrient, such as nitrogen, is just as bad as giving it too little, and it just adds to waste,” Rezac said.“In today’s farm economy, we aren’t farming to rake in a profit. We’re not making money, and we’re farming to lose as little as possible. I know focusing on environmental stewardship also makes economic sense, when it’s done right. I strongly believe that with the right policy and the right incentives, farmers can keep improving across the board.”Lyons-Blythe, who manages more than 5,000 acres of native grassland and crop ground as well as running 300 cows and calves and an additional 250 heifers in the Flint Hills of Kansas, said her operation uses a variety of technologies to improve efficiency and, as a result, mitigate environmental concerns.That includes using genetic testing to enhance meat quality, feed efficiency and growth.“Efficiency traits directly affect beef sustainability,” Lyons-Blythe said. “An animal who will reach harvest faster and yet produce a high-quality meat product will impact the environment for a shorter period of time. Of course, not all ranchers have this technology available because of price and availability. But it is the responsibility of seedstock ranchers like me to provide the superior genetics that have been proven through technology. This technology allows us to produce the same amount of beef today that we were producing in the 1970s with 33% fewer animals.”ETHANOL INPUTLeading up to the hearing, the committee received a letter from the American Coalition for Ethanol, calling out the EPA for its handling of the science used in calculating corn ethanol’s carbon footprint as well as the agency’s issuance of small-refinery waivers to the Renewable Fuel Standard.Discussion about agriculture’s role in climate-change mitigation, said ACE CEO Brian Jennings, needs to include corn ethanol’s role.“Congressional action on climate could be viewed as a cost or a chance for new economic opportunities,” Jennings said in the letter.“As you know, U.S. farmers are already under tremendous financial stress. Net farm income is collapsing, expenses are on the rise, and bankruptcies are at the highest level in the last decade. Ongoing trade tensions resulting in lost markets and weather-related disasters are only adding insult to injury.”Jennings said EPA’s “mismanagement” of the RFS has “undermined” ethanol demand.“The economic stakes are high,” he said. “Farmers are obviously concerned that climate policy could result in increased costs for fuel, fertilizer, and other inputs. But there is also opportunity. Congress could provide rural America with concrete benefits from climate-centered policies that outweigh potential negatives, such as recognizing the role agriculture can play to mitigate climate change and increasing the use of low-carbon fuels.”Jennings said corn ethanol could reduce emissions by 50% to 60% compared to gasoline.“ACE believes unlocking the marketplace for low-carbon fuels creates the economic driver to help farmers adopt practices that maximize atmospheric carbon sequestration in soil,” he said.Todd Neeley can be reached at [email protected] him on Twitter @toddneeleyDTN(PS/AG/ES)© Copyright 2019 DTN/The Progressive Farmer.

Real Betis Coach Quique Setien is proud of his team’s performance after a 2-1 Europa League victory at the San Siro.Setien relished the “prestige of beating Milan on their own turf” and even suggested the lead would have been wider after dominating the game.“This is an important victory for us, not just for the three points that put us top of the group, but also for the prestige of beating Milan on their own turf,” said Setien in his Press conference via Football Italia.“The truth is that we put in a great performance, especially in the first half, although Milan had some chances in the second. If you got the sensation we were time-wasting in the final 15 minutes, then I’ll have a talk with my players, because I do not like that approach. I apologise if we gave off that idea.Serie A Betting: Match-day 3 Stuart Heath – September 14, 2019 Considering there is a number of perfect starts so early in the Serie A season, as well as a few surprisingly not-so perfect ones….“Milan were perhaps a little surprised by our style of football, as we forced them to play long balls. We depend on possession in all our games and this time we were also able to score two goals.“Milan are a great team, though, and we saw that in the final stages. It was a memorable game for us and our fans, so we are happy to dedicate it to them. This is my first experience in Europe, but the team showed great character and confidence.“Winning or losing doesn’t change my perception of a performance, because it can depend on many factors beyond our control. The important thing is to play well, because that gives you a better chance of winning. Today reinforced that concept.”
Miralem Pjanic admits Juventus need to improve their Champions League form as he suggested Atletico Madrid have a “similar philosophy” to the Serie A side.The first leg of the Round of 16 is at the Wanda Metropolitano Stadium on Wednesday evening.And Pjanic is wary of the threat posed by Diego Simeone’s men owing to their tactics and style of play.“Their philosophy is not easy to deal with at all, so it’s up to us to control both games and most importantly try to score a goal in Madrid,” the midfielder told Football Italia.“Atleti do have a lot of similarities with Juve, as both teams are solid, allow few spaces and don’t concede many goals.“They are very aggressive when marking or pressing opposition players, whereas we have stronger individual talents. That is where we must make the difference over the two legs.”The Champions League Final this season will be played at the Wanda Metropolitano.“They’ll be even more motivated because they want to play the Final on home turf, having played two in the last five years. They’ve got the same record reaching the Final in that period as Juve.”La Liga Betting: Match-day 4 Stuart Heath – September 14, 2019 Despite it being very early into La Liga season, both Barcelona and Real Madrid have had unprecedented starts to their campaigns. With this in…Pjanic claims the arrival of Cristiano Ronaldo means Juventus are among the favourites to win the Champions League, which would be their first since 1996.Everyone. Everywhere. #GETREADY#AtletiJuve #UCL #FinoAllaFine #ForzaJuve pic.twitter.com/yyuRKtMpMc— JuventusFC (@juventusfcen) February 17, 2019“We feel strong, even if we’ve been knocked out of the Coppa Italia by Atalanta. Other than that, we’ve only had great results this season.“There have been some more complicated matches lately, so we need to improve in two or three areas when facing these knockout ties.“We’ve conceded too many goals recently and it is not like us. The team must defend as a unit and when I say all together, I really mean it. Even the strikers must participate in helping the defence.“This is an important year and we’ve got to focus.”
