Human Endurance: Is It Evolutionary?

first_imgSome people are gluttons for punishment.  Many a couch potato is probably content to watch an Ironman or Ultramarathon on HDTV from a recliner, but the ones who take part in the grueling endurance contests gaining popularity illustrate some human capabilities scientists are only beginning to understand.  Nature1 described one called the Primal Quest adventure race:Trek 125 kilometres, and cycle 250 more.  Kayak 131, rappel through canyons for another 97, and swim 13 in churning whitewater.  Throw in some horseback riding and rock climbing; spread it all over six days in the blistering Utah heat; and never stop to sleep.Only some contestants complete this “adventure torture” but the fact anybody does has attracted the attention of physiologists.  Participants burn more calories than can be replaced by food.  Some scientists focus on the chemistry of fat metabolism for answers; others look at genetics.  Still others think the explanation is in the minds of the winners, not their physiques.  One researcher did not think the bodies of ultraracers are significantly different from those of other active people.  “The brain is the oft-overlooked organ that sets ultraracers apart,” he said; “– they are mental freaks, not physiological ones.”    Freaks or not, ultraracers carry out feats that push their physical abilities to the limit and seemingly beyond.  Evolutionists look to something in human ancestry to explain abilities only a few today are using.But even couch potatoes may have something of the endurance racer in them.  Daniel Lieberman, a biological anthropologist at Harvard University in Cambridge, Massachusetts, argues that the human body is well-adapted to long-distance running, as an evolutionary hangover from our hunting and scavenging days.  Ultraendurance racers “are able to be freaks because evolution has enabled us”, he says.  A body capable of jogging tens of kilometres at a time helped our ancestors survive, he says.  Fuelled by plentiful water, energy bars and yet more training, that body can complete the 90 or more kilometres of an ultramarathon.The article ended with an anecdote about one researcher who joined them to study them.  “If this is true, then many of those who study ultraendurance racers have also embraced their evolutionary past,” reporter Helen Pearson remarked.  A sidebar lists five of the most notorious international competitions.1Helen Pearson, “Physiology: Freaks of nature?”, Nature 444, 1000-1001 (21 December 2006) | doi:10.1038/4441000a.It was Lieberman who dazzled us in the 11/18/2004 entry about human endurance running.  This would be a good time to re-read that fascinating article that explained how unique it is in the animal kingdom, and how many physiological adaptations have to work together to make it possible.  The myth that all these remarkable traits converged in humans so that they could hunt and scavenge better takes great faith.  No other animal requires swimming, cycling, kayaking, trekking and running for six days in Utah heat to catch a meal, leastwise our chimpanzee brethren who were supposedly evolving alongside us in Africa in the same environment (09/01/2005).  The widespread phenomenon of overdesign, beyond what would be expected for mere survival, is a “major problem in quantitative evolutionary design” (see 06/19/2002).  The evolution of the couch potato lifestyle would be much easier to explain.  At least there is a known physical law behind it: entropy.    As usual, Darwinian evolution is just a mythoid attached to the observational facts of the phenomenon, and contributes nothing to our understanding.  The science of human physiology has long prospered by viewing the body as a paragon of design.  If the body was created, then any attempt to “embrace one’s evolutionary past” is tantamount to hallucinating.  Lieberman is right about one thing; he and his fellow evolutionists have an “evolutionary hangover.”  Dar-wine has a deleterious effect on a researcher’s cognitive and logical faculties.  Suggested New Year’s resolution: kick the habit and sober up.(Visited 14 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

NBC names Hoda Kotb as Lauer replacement on Today

first_imgNEW YORK, N.Y. – NBC News opened the new year Tuesday by appointing Hoda Kotb as co-anchor of the “Today” show’s first two hours with Savannah Guthrie, replacing Matt Lauer following his firing on sexual misconduct charges in late November.Kotb, 53, will continue to co-host the show’s fourth hour with Kathie Lee Gifford.It will be the first all-female team headlining “Today” in the show’s 65-year history. Diane Sawyer and Robin Roberts blazed that path for ABC’s “Good Morning America” in the 2000s, but morning shows have traditionally paired a man and a woman as host. With an audience dominated by women in an era where news of badly behaving men is frequent, the Guthrie-Kotb pairing may be particularly timely.“Today” won’t be an all-female zone in its first half, however, with longtime weather forecaster Al Roker and correspondent Carson Daly as regulars. Megyn Kelly hosts the show’s third hour.“This has to be the most popular decision NBC News has ever made and I am so thrilled,” Guthrie said on Tuesday, announcing the appointment on the air.“I am pinching myself,” said a beaming Kotb, sitting beside her. “I think we should send some medics to Alexandria, Virginia, where my mom has likely fainted.”Lauer’s eventual replacement had long been the subject of internal angst but with a sudden decision forced upon the network, Kotb’s performance made it easier. She’s subbed for Lauer since the day he was fired and “Today” has won four straight weeks in the ratings, after having spent much of the past few years in second behind ABC.“Hoda has seamlessly stepped into the co-anchor role alongside Savannah, and the two have quickly hit the ground running,” NBC News Chairman Andy Lack said in a memo to staff on Tuesday. “They have an undeniable connection with each other and most importantly, with viewers, a hallmark of ‘Today.’”Lack said Kotb “has the rare ability to share authentic and heartfelt moments in even the most difficult news circumstances. It’s a tribute to her wide range and her innate curiosity.”It’s common for television shows with job openings to hold informal tryouts of potential hosts. With Kotb’s immediate success, potential replacements like Willie Geist or Craig Melvin didn’t get that chance.Lauer had been a fixture at “Today” since the mid-1990s before his abrupt firing for what NBC called “inappropriate sexual behaviour” with a colleague. Other complaints and reports of crude behaviour followed.He was the second television morning host fired in a week, after CBS News axed Charlie Rose just before Thanksgiving on sexual misconduct charges. Rose was one of three “CBS This Morning” hosts with Gayle King and Norah O’Donnell, and CBS has yet to name his replacement. Substitutes have included Vladimir Duthiers, Bianna Golodryga, Dana Jacobsen, John Dickerson and Anthony Mason.Kotb joined NBC News in 1998 as a “Dateline NBC” correspondent, after working in local news in New Orleans. Her public profile increased with her wine-soaked pairing with Gifford on the show’s informal fourth hour.She was born in Norman, Oklahoma, to parents of Egyptian descent, and raised in Morgantown, West Virginia.Ben Bogardus, a journalism professor at Connecticut’s Quinnipiac University, said Kotb’s selection was a good one “because it reinforces the sense of a family coming together after a shared trauma.” The timing is important for NBC, because “Today” will get a burst of attention next month with the Winter Olympics.last_img read more

Love can cure all addictions Mimi Chakraborty

first_imgTollywood actor Mimi Chakraborty who cut her teeth in acting in the television serial ‘Gaaner Opaare’ many years ago has recently completed playing the role of a hapless drug addict in the Shagufta Rafique film, Mon Jaane Na. Having studied the role in all its depth, Mimi found herself preparing hard for her part and is now looking at innovative promotions for the film.Excerpts from an interview: Tell us about your role in the film, Mon Jaane na… Also Read – An income drop can harm brainI play the character of Pari who is a shy orphaned girl married off to a taxi driver named Amir (Yash ) by the local maulvi. Soon she discovers some secrets of Amir’s life and decides to leave home. For two years she goes missing and Amir frantically looks for her everywhere and when she is finally found, she has transformed into a reckless drug addict and gone into prostitution. The story is how the couple battles this situation and overcome it. In the end, it is love which wins the day. Also Read – Shallu Jindal honoured with Mahatma AwardTell us how you prepared for this role: Playing a drug addict was difficult. I read a lot about addiction on the internet. I talked to people who had undergone the ordeal. I have a friend who has recovered now, so I spoke to him. Shagufta gave me some clips so I looked at them but there were no acting workshops since Shagufta did not want anything to come between me and my natural self. Tell us about the director of this film? This happens to be Shagufta’s first directorial venture. One reason why I chose this film is because of it has strong content. These days, people do get into drugs and then a whole lot of problems get unleashed. These people suffer, they become social outcasts. Rehab is also not the only solution in this situation. The film rightly depicts that love and care can heal the victim permanently. You decided to do playack also in this film… There was nothing planned about it and I’m totally nervous about how the audience will respond to it. In fact, I’m more nervous about it than I was about my first film. But, of course, I love singing… Your fitness plan since you have lost weight? I had to lose weight for this film. There is no diet as such that I follow. I don’t eat anything after 8.30 pm at night, and in the morning I don’t wake up to tea or coffee, I eat fruit instead. I work out for about two hours at the gym every day but on a Sunday, I break all rules and have sweets. Your next project? I’m doing a film with Birsa Dasgupta next. It’s a rom-com.last_img read more
