A paleoanthropologist believes our ancestors ran nudist colonies for 830,000 years before inventing clothes, and can prove it from lice genes. The story is on Science Daily. By comparing head lice and clothes lice genomes, David Reed at the Florida Museum of Natural History at the University of Florida came up with a date for the invention of clothing: 170,000 years ago. With taxpayer funding via the National Science Foundation, Reed pieced together clues from genes, ice cores and evolutionary theory to weave his story, which includes a long period of social nudity. According to Reed, humans lost their body hair one million years ago, but started wearing clothes 170,000 years ago. That leaves 830,000 years for our imaginary ancestors to cavort around in birthday suits. “It’s interesting to think humans were able to survive in Africa for hundreds of thousands of years without clothing and without body hair, and that it wasn’t until they had clothing that modern humans were then moving out of Africa into other parts of the world,” he said. Parts of this story don’t hang well together, though. Africa is pretty warm, but he said they invented clothes to survive one of the Ice Ages, presumably in Europe. Ian Gilligan, another colleague on Gilligan’s island of Australia, said, “It means modern humans probably started wearing clothes on a regular basis to keep warm when they were first exposed to Ice Age conditions,” even though there were warm areas they could have remained in, like Africa. But if they needed warmth, why did humans lose their hair in the first place, and why didn’t other mammals invent clothes? The alleged human ancestors could have dug burrows, or stayed by the fire they were inventing while evolving technology. Of course, there’s no way to know what early evolving people were wearing, if anything, because textiles do not preserve well in the fossil record. And estimating the evolution of clothing by lice genes assumes that humans and lice evolved, a circular argument. It doesn’t matter to Reed, though. It would be impossible to go back in time and check his theory out. Maybe next he will investigate the evolution of shame, and the evolution of evolutionary storytelling.One can’t make a case on such threadbare evidence. This contrived tale is merely a fig leaf, made up of NSF dollars, covering up shameful science. Don’t tell the Discovery Channel, Science Channel and History Channel. Now that the FCC has apparently opened the door to more nudity on television (Fox News), those apeman documentaries could really start to get risque. The lice, though, may love all the new real estate.(Visited 25 times, 1 visits today)FacebookTwitterPinterestSave分享0

28 November 2011 The final day ended with a tense inward nine for Otto. He had begun play with a three-shot lead, on 14-under-par, and he was still three shots clear with six holes to play, but bogeys at the 13th, 15th, and 16th saw him slip into a tie for the lead.

The victory was timeous for Otto. It moved him up from 80th in the Race to Dubai standings to inside the top 60, which secured him a place at the lucrative Dubai World Championships presented by DP World. Back on topHowever, he quickly moved to the top of the leaderboard again on the next hole, the 17th, sinking a birdie to take him level par for the day. A par on the final hole sealed victory after an up-and-down day that featured four birdies and four bogeys. South African dominationIt was also the tenth victory by a South African in their national Open in the last 11 years. Since 2002, the only man to break the South African monopoly was Scotland’s Richie Ramsay at Pearl Valley Golf Estate. It was only Otto’s second victory on the European Tour, following his win in the Italian Open in 2008. It was, however, his third win of 2011. He previously claimed the Dimension Data Pro-Am and Platinum Classic on the Sunshine Tour, which co-sanctioned the South African Open. Otto’s win took the number of South African wins on the European Tour in the 2011 season to an astonishing seven. The others to claim titles : Ernie Els (SA Open), Louis Oosthuizen (Africa Open), Charl Schwartzel (Joburg Open and US Masters), Thomas Aiken (Spanish Open), and Garth Mulroy (Alfred Dunhill Championship). Hennie Otto’s eyes were clenched tightly shut, his arms raised, club in the left hand, and his face lifted skywards after he sank the putt that secured him his first South African Open title at Serengeti Golf & Wildlife Estate on Sunday. LEADERBOARD Defending champion Ernie Els had a forgettable showing. After opening with successive three-under-par 69s, he slumped to a 76 and 79 in the last two rounds to finish on five-over-par 293, in a tie for 69th place. “This one is special because it’s our national Open,” he said afterwards. “You dream of these things, and with the names that are on the trophy, you can really be proud. When it comes your way you must enjoy it.” Austria’s Bernd Wiesberger placed Otto under pressure with a final round of four-under-par 68, which included three birdies on the first five holes. He finished on 13-under 275.
Share Facebook Twitter Google + LinkedIn Pinterest There have been a lot of changes in the last two weeks and the conditions have been really good. The first thing we did was start planting corn. We planted our first field on April 28. The soil worked up really nice — even the fields we spring plowed.Our first corn is up and out of the ground now. We got everything planted that is ready to plant with corn. We have to take 100 acres of wheat off for silage in a week or two and then we are planting corn there for silage. We are going to focus on planting soybeans this week.There is a 90% chance of rain tonight and a cold front is coming. It sounds like after that we are going to have more normal temperatures. We haven’t caught any rains and we are due for some, at least right where I am. Other parts of Wayne County have gotten rains but here in the northern part of the county we have missed them.I think a 40% chance was the highest chance I saw for the rest of the week after tomorrow. Unless we get a whole bunch of rain I think we could finish up with soybeans this week.The hay is coming along. With the 80-degree plus temperatures it has caught up from being so behind. I would have never thought it would be this nice for this long, but you just never know. Things are moving along very well.
As part of a new Master Certified Green Professional designation, NAHB worked with GreenBuildingAdvisor to develop a rigorous training course covering green home building, full of building science and quality construction details. This course premiered at the International Builders Show in Las Vegas just last week.After nearly a full day of building science instruction, students in the class spend most of the second day working in groups on real projects (often their own). They use all the GBA resources, but particularly the construction details library, strategy generator, and product guide.Some great feedbackSeveral builders stopped by the NAHB Green Building Education booth after the course. Dennis Gray (P.E., LEED-AP, CGP – Wasatch Engineering) from Park City, Utah had this to say:“The Advanced Green Building: Building Science class is an excellent addition to the NAHB education offerings. Mostly a continuation of Green Building for Building Professionals, the thing that made it special to me was the time spent on the science of moisture migration through building structures, what this impacts, and how to control it. What was great about the class approach was that it concentrated on providing the builder with the knowledge to understand how moisture problems are created, and the science behind solutions. The breakout sessions, where we worked on actual projects, was a very effective learning process. Any builder who is designing and building high performance green homes is well advised to take this class – well worth it.”Don Ferrier of Ferrier Homes in Ft. Worth, Texas is a leading member of the NAHB Green Building Subcommittee who worked with NAHB and Green Building Advisor on this new course.“I am very impressed with the GBA website,” says Ferrier. “Its depth and breadth is a good fit for the new Master Certified Green Professional designation, building substantially on the Certified Green Professional program.”Coming to an HBA near youLocal home building associations around the country will be offering this course; the first will be in eastern Connecticut. I will be teaching the course for Build Green NH in March. Check out the NAHB education website (search on Advanced Green Building) to see when this class might be offered in your area. We don’t think you will be disappointed!NOTE: At this time, the Master Certified Green Professional designation is not yet available. This is because the other required course for the designation, Green Project Management, has not premiered. The Green Project Management course will premier late this spring or early summer.
