Three recent news stories about mammals involve time. Does nature time things well, or do evolutionists tell swell things about time? Time will tell.Placental mammals – Watch those assumptions: How much can you trust dates that can vary by 50%? A report in Science Daily says the new “consensus” date for the appearance of placental mammals just jumped from 122 million years ago to 84 million years ago. The article mentions assumptions three times, though, with serious caveats about those dates: “However, this discrepancy may not be real, but rather appear because of the violation of implicit assumptions in the estimation procedures, such as abrupt acceleration of evolutionary rate entangled with gradual variation and large-scale convergent evolution in molecular level.” Later, “They emphasize the necessity to scrutinize the implicit assumptions adopted by the models of molecular evolution and to develop procedures which rely little on those assumptions.” A follow-up question: what are the new assumptions of the new study?Laotian Rock Rat — Yep, It’s a Living Fossil: The unusual rat-like mammal found in a Laotian food market in 2005 (05/16/2005) is a living fossil, reported National Geographic News. Some researchers claim that it “belongs to a family of rodents thought to have gone extinct 11 million years ago.”Bears – Keeping fit while sleeping: On much shorter time scales (months), bears manage to keep most of their muscle strength during the winter hibernation. Science Daily reported that “Bears in this study exhibited remarkable conservation of muscle function…. In spite of a size difference of almost three orders of magnitude and a 30 degree Celsius difference in torpor body temperature, the black bear may conserve muscle function to the extent of or perhaps better than small-mammal hibernators.” How the authors entered Colorado bear dens to take the measurements sounds like an adventure to be told somewhere.Anyone see evolution here? Anyone see millions of years here? Always scrutinize those implicit assumptions.(Visited 6 times, 1 visits today)FacebookTwitterPinterestSave分享0
Top Reasons to Go With Managed WordPress Hosting Tags:#start#startups dana oshiro Related Posts A Web Developer’s New Best Friend is the AI Wai… After tech heavy hitters like Jason Calacanis, Robert Scoble and Fred Wilson expressed public outrage over its pay-to-play fees, the Keiretsu Forum has begun waiving fees for early-stage startup presentations. According to PeHUB’s Deborah Gage, the network is asking its chapters to disregard presentation charges for companies with less than $500,000 in capital and for those trying to raise less than $500,000 from investors. In early October ReadWriteWeb covered the uproar Jason Calacanis caused when he spoke out against pay-to-pitch VC presentations. Said Calacanis, “It’s low-class, inappropriate and predatory for a rich person to ask an entrepreneur to PAY THEM for 15 minutes of their time.”Since then the vocal entrepreneur/investor has been publicly outing organizations with pay-to-play presentation models. Recently he called on startup companies to boycott events like New York’s Venture Summit and AlwaysOn’s Venture Summit Silicon Valley. Both events charge startups as presentation sponsors before they can demo to attendees. To counter these events, Calacanis even promised to “launch competing, fee-free events directly opposite [these pay-to-play] events.”Meanwhile, Keiretsu Forum user Steve Bell points to demo costs on Calacanis’ TechCrunch 50 floor as an example of the same pay-to-pitch tactics that the entrepreneur is rallying against. Having looked at the argument, we’re unsure whether these fees can be classified as presentation fees or merely sponsorships. Perhaps this is where the ethical lines become really blurry: Because most tech events offset the cost of production with sponsorships, at what point do we draw the line between sponsor presentations and pay-to-pitch demos?

Taking a serious note of the ongoing public spat between its two MLAs from Haridwar in Uttarakhand, the BJP on Friday set up a committee to look into the issue. Pradesh BJP president Ajay Bhatt constituted a three-member committee to probe the continuing war of words between Khanpur MLA Kunwar Pranav Singh Champion and Jhabreda legislator Desraj Karnawal, State party media head Devendra Bhasin said. The panel has been asked to submit its report to the party at the earliest so as to take further action in the matter, he said. Mr. Bhasin said the committee will be headed by party general secretary and MLA Khajan Das and senior party leaders Vishwas Dabur and Kuldeep Kumar will be its members. The two MLAs have been casting aspersions on each other in public for over a fortnight prompting Chief Minister Trivendra Singh Rawat to intervene last week. The duo was summoned by the Chief Minister to his residence last week and made it up with each other on Mr. Rawat’s advice but the truce proved temporary as they resumed their fight only a few days later. Wrestling challengeThe trouble began after Mr. Karnawal cast doubts on Mr. Champion’s educational qualifications and his sports credentials. Mr. Champion hit back by challenging Mr. Karnawal to a wrestling bout at a stadium in Roorkee.
