Don’t Just Sit There; Evolve

first_imgHave you ever wondered why your body doesn’t evolve?  After all, it is kind of like a population of trillions of organisms.  Why shouldn’t it follow the rules of natural selection?  Philip Ball asked this question in [email protected] recently.  “Evolution is usually thought of as something that happens to whole organisms,” he teased.  “But there’s no fundamental reason why, for multicelled organisms, it shouldn’t happen within a single organism too.”    So why haven’t you evolved into something else by now?  The answer is as fascinating as it is unexpected: your body works overtime to keep you from evolving:It’s not easy making a human.  Getting from a fertilized egg to a full-grown adult involves a near-miracle of orchestration, with replicating cells acquiring specialized functions in just the right places at the right times.  So you’d think that, having done the job once, our bodies would replace cells when required by the simplest means possible.    Oddly, they don’t.  Our tissues don’t renew themselves by mere copying, with old skin cells dividing into new skin cells and so forth.  Instead, they keep repeating the laborious process of starting each cell from scratch.  Now scientists think they know why: it could be nature’s way of making sure that we don’t evolve as we grow older.And it’s a good thing the body prevents you from evolving.  Ball explains that mutants would have a selective advantage to hijack your other cells without doing any work: “mutant cells that don’t do their specialized job so well tend to replicate more quickly than non-mutants, and so gain a competitive advantage, freeloading off the others,” he explained.  “In such a case, our wonderfully wrought bodies could grind to a halt.”    My, what would Charles Darwin think of that. This is too funny.  Not only did the pro-evolutionist writer Philip Ball knock off another Darwinian concept in the pro-Darwin rag Nature, he praised our “wonderfully wrought bodies” with their “near-miracle of orchestration” in language that would warm the heart of any believer in intelligent design.  My, what would Phillip Johnson think of that.(Visited 6 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Sophie Kanza plays her part in building a supportive, united and tolerant society

first_imgPhoto supplied by Sophie KanzaPlay Your Part ambassador, Sophie Kanza is the co-founder of the Sophie A. Kanza Foundation, which she runs with her sister Louise, with whom she migrated to South Africa from the Democratic Republic of Congo over 20 years ago. The Foundation is a fully self-funded, fundraiser and youth led organisation. It focuses on recruiting youth as volunteers to collect and distribute food, clothes and toiletries to those in need. Sophie hopes that by encouraging youth to go out and make a difference in other people’s lives, she is playing her part in building a supportive, united and tolerant society.Through the Foundation, Sophie uses Pan-Africanism to spread love, unity, peace and tolerance in a number of youth volunteerism projects. The Foundation’s volunteers are made up of mostly Congolese and South African youth. Other African nationals also participating are from other countries like Zimbabwe, Botswana, Zambia, Tanzania, Ivory Coast, Gabon and Malawi.In efforts to encourage love, unity, peace and tolerance, the Sophie A. Kanza Foundation created a social awareness campaign called ‘#Singabantu – We Are Human’ to challenge the negative stereotypes of foreign nationals living in South Africa. Out of this campaign came a short film of the same name. The film was shot in the remains of a Rosettenville house burnt to the ground during service delivery protests that turned into a nationwide wave of attacks  believed to have been driven by xenophobia. The film has, since its launch on Africa Day 2017 (25 May 2017) won the United Nations Alliance of Civilizations Plural Plus Award and been nominated at the Soeul Film Festival South Korea, which took place in May 2018 and the Africa Film Festival NYC USA which is in  August 2018.For more information on the Sophie A.

8. If a farmer became President…

first_imgShare Facebook Twitter Google + LinkedIn Pinterest Though we tried to mostly stay out of the historically ridiculous 2016 presidential campaigns, it would be impossible to cover the last year of news without some references. Ty Higgins’ take on how things could be different if a farmer resided in the White House was a very popular post leading up to Election Day.last_img

Ohio’s record rainfall leaving some farmers on the sidelines

first_imgShare Facebook Twitter Google + LinkedIn Pinterest During the wettest yearlong period in Ohio since 1895, the state is lagging the furthest behind in planting corn and soybeans compared to all states that plant the crops, according to experts from The Ohio State University and federal reports.From June 1, 2018, to May 31, 2019, average rainfall across Ohio totaled 52 inches, which is about 10 inches above the mean for that period in the last decade, said Aaron Wilson, climate specialist for Ohio State’s College of Food, Agricultural, and Environmental Sciences (CFAES).“We’ve had very wet soils for a very long time,” Wilson said.As a result, only 50% of Ohio’s corn crop and 32% of its soybean crop was planted by June 9, a report from the U.S. Department of Agriculture shows. By now, Ohio typically is 96% done with planting corn and 89% done with soybeans.A brief slowdown in rainfall during the week of June 3 sent more Ohio corn and soybean growers out into their fields to plant, but that likely will prove to be only a temporary reprieve. The next two weeks are expected to bring above-average rainfall in the state, with the heaviest amounts in southern Ohio, Wilson said.“We’re going to return to a more saturated pattern,” he said.The growers who have been able to plant a corn or soybean crop likely will have to contend with other challenges that come with a lot of rainfall: more weeds, pests, and diseases.“Right now, you see a lot of really tall weeds already,” Wilson said.Farmers who planted wheat and forages, such as alfalfa, have noted poorer conditions of these crops also due to the weather, he said.“No one is really escaping challenges this year,” Wilson said.For those planting corn in June, yield losses are likely—even if the grower has switched to a shorter-season variety, said Peter Thomison, a corn field specialist with CFAES. The losses hinge on growing conditions after planting, but they could be more than 50% for some farmers, he said.The bulk of Ohio’s corn and soybean acres are typically planted by May 25 each year, with corn being finished earlier in the month.For growers planting soybeans, there’s still time, but some loss in yields should be expected, said Laura Lindsey, a soybean specialist with CFAES.Soybeans planted in late June produced yields that were 20% to 40% lower than soybeans planted by mid-May, Lindsey said, referring to data from research plots. Yield loss from delayed planting depends a lot on growing conditions the remainder of the year, Lindsey said.“I keep hearing farmers say they need just two days in a row or three days in a row of dry weather, and they haven’t been able to get that.”To view the USDA report comparing states’ crop progress, visit https://www.nass.usda.gov/Publications/Todays_Reports/reports/prog2419.pdf.last_img read more

The Buyer’s Process Isn’t What You Think

first_img Essential Reading! Get my 3rd book: Eat Their Lunch “The first ever playbook for B2B salespeople on how to win clients and customers who are already being serviced by your competition.” Buy Now I watched a group of salespeople make a sales call today. The prospective clients were very engaged throughout the sales call, including the presentation (which was, thankfully, more of a dialogue). The salespeople were successful, and the buyers committed to taking the next step in the process.While the call was wrapping up, one of the sales people ask the buyer the question: “What are the most important factors for you in determining who your partner will be for this project?” The buyers both sat quietly for a minute and look at each other. Then, the more senior of the two buyer said, “You know, we really don’t know what factors we’re going to use to decide.”This isn’t the buyers first time making this purchase. This group of buyers has a very good idea of what they need. There is plenty of information about this particular product available and easily accessible on the web. Companies in their space routinely receive calls from sales people who sell this particular product. Both of the buyers are smart, and they know their business.So, are we to assume that they’re 67 percent through the buying cycle? Are we to assume that sales people can add no value in helping them determine what they need and the trade-offs that they might make? Are we to assume that they know as much as a the salesperson and that information and ideas are no longer useful because they know as much or more?Generalizations are lies. Sometimes we confuse facts and statistics for absolute truths. Much of the information we hear about how buyers buy is based on how consumers buy, not how complex sales are made (even if some would push for complex sales to be made transactional).We take buyers as we find them. Despite any facts, figures, or research, we can find them anywhere along the buying journey. Working to understand where they are and how to create value for them is critical. It’s dangerous to make assumptions, especially when you could just as easily ask the questions necessary to uncover what a buyer really needs.QuestionsWhat assumptions do you make about what your prospects already know?What assumptions do you make about what your dream clients value and how they will decide?What questions do you ask to elicit where they are in their “process?”last_img read more
