More Examples of “Convergent Evolution” Claimed

first_img(Visited 186 times, 1 visits today)FacebookTwitterPinterestSave分享0 Traits evolve by common ancestry, evolutionists claim—except when they don’t, which is all too common.“Convergent evolution,” the Darwinists’ explanation for similarities that could not have evolved by homology or common ancestry, keeps popping up in the most unusual places. For example, Evolution News & Views analyzed cases among marine creatures that hit on identical swimming strategies in groups as diverse as flatworms, cephalopods and fish. Also called homoplasy, convergence seems to be the rule more than the exception, as these articles suggest:Spider venom is very similar to centipede venom, even though their branches split 500 million years prior, Science Daily says. Does this falsify evolution? No, it confirms it, Science Magazine claims. “It’s cool that it happens in similar ways for two very different and unrelated arthropod groups,” says Trine Bilde, an evolutionary ecologist at Aarhus University in Denmark. But, “it is common in biology that evolution comes up with similar ‘solutions.’ ”Natural sunscreens are showing up in very diverse organisms, Science Magazine reports. The sunscreens consist of mycrosporine-like amino acids (MAAs) that provide protection from solar UV rays. They have been found in “bacteria, algae, and marine invertebrates … marine fishes … amphibians, reptiles, and birds, suggesting that such internal sun protection could be widespread.”Fly developmental switches have been lost and regained in various groups of flies, Science Daily claims. “The genes that drive embryonic polarity are not conserved across flies and their evolutionary replacement does not seem to be rare at all,” a researcher at U of Chicago says. “The hijacking of this early developmental pathway by novel or newly evolved genes happens at a much higher frequency than previously thought.” It also happens “in a very short amount of time,” he adds.Like human, like fly: An article on PhysOrg claims that the “Biological clockwork of human beings and flies [is] comparable” despite them being extremely far apart on Darwin’s tree diagram. The article includes watchmaker language: “Although both homologous receptors do not act in an identical way, the fact that they modulate the expression of clock genes in Drosophila as well as in mammals demonstrates that very distant organisms, displaying different circadian activities, can present the same type of biological clock gears.”Diving birds: How many specialized adaptations would it require for a flying bird to be able to dive and swim underwater? It would seem to require multiple mutations to eyes, wings, feathers, lungs, beaks, feet and other parts, to say nothing of instincts.  Science Daily shouts, “Go fish!” in another case of convergence: “A new study of some primitive birds from the Cretaceous shows how several separate lineages evolved adaptations for diving.”Bee together: Convergence is also claimed for independent cases where solitary insects evolved group therapy. Science Magazine published a paper by 52 evolutionists claiming, “We compared the genomes of 10 bee species that vary in social complexity, representing multiple independent transitions in social evolution….”Warning cues: What organisms could be more diverse in their evolutionary history than plants and animals? Yet they evolved warning cues independently, another article in Science Daily asserts. This problem dates back to Darwin and Wallace. Readers may be unaware that “Despite a number of attempts, however, no satisfactory evolutionary mechanism for the origin of warning cues has been proposed.” Maybe giving it a name like “concurrent reciprocal selection” can help.Update 6/15/15: Four evolutionists responded in PNAS to an earlier paper by Schopf, a microfossil hunter, who had pointed to “extreme stasis” in bacteria over billions of years (2/04/15). Apparently they don’t like his appeal to long ages without continuous Darwinian evolution. Their solution? Convergent evolution, of course: “We hypothesized that cyanobacterial (and possibly bacterial) evolution is characterized by serial convergence… For example, convergence has also been observed in cyanobacteria dwelling in hot springs, which are considered one of the oldest habitats with living organisms…. In conclusion, we are convinced that the long evolutionary stasis in bacteria is only elusive and might be explained by serial convergence of phenotypic traits, which masks possible continuous metabolic, genetic, and ecological changes.” This new Darwinian maxim might be termed, “the more things change, the more they stay the same.”Convergent aliens: Speculating about independent origins of similar traits can get downright silly. Live Science printed a speculation by Fergus Simpson (NOT Homer’s brother) who thinks aliens will be bear-size. Don’t believe it? He has the math to prove it. Some critics aren’t buying it. They say it’s “not clear if humans are a random sample of intelligent beings.”This last one is like the joke about the two fishermen who found a good fishing spot. One suggests, “How’s about we mark an X on the boat where the fishing is good?” The other fisherman, appalled at this expression of imbecility, tries to reason with him. “That’s stupid. Can’t you see that would never work? What if we take out another boat next time?”Homoplasy is quite amazing. It’s astonishing that so many evolutionists, trained at different universities in different countries, would converge on the same illogic over and over.last_img read more

Standard, Spar in ‘mobile money’ venture

first_img30 March 2010South Africans will soon be able do more than just pick up a bag of groceries at their local Spar – they will also be able to send money instantly to friends or family anywhere in the country via mobile phone.Standard Bank is introducing a new person-to-person money service, Instant Money, which will enable clients to send and receive money through retailer Spar’s network of 850 stores countrywide, with the transaction information being sent via mobile phone.Instant Money has been developed in such a way that the service can be accessed on even the simplest mobile phone models and across networks. The service will initially be available from Spar stores in the Eastern Cape.Standard Bank South Africa CEO Sim Tshabalala said the new service means people no longer have to take the risk of giving an envelope full of cash to a middleman – like a friend or a taxi driver – and telling them where to deliver it.“It’s a way for users who don’t have a bank account to get access to financial services,” he said in a statement this week.“Financial services are largely limited to urban areas at the moment, mainly because of the expense of rolling out banks and services in less affluent areas. What this means is that most people in rural areas operate on a cash basis.”Mobile money transfers, paymentsLeading market research organisation Gartner believes money transfers and payments over mobile phones will be among the top 10 most important mobile applications by 2012 – ahead of location-based services, search and browsing.Money transfers are already popular in a number of developing countries, and will continue to attract more users, according to Gartner’s Top 10 Consumer Mobile Applications for 2012.“With Instant Money, people can now transact and send money without the need for a bank account,” said Tshabalala. “It is estimated that some 35-million South Africans have a cell phone, while only 11-million have a bank account.”Mobile money transfers not only offer a safer, more reliable way to send cash, but could breathe new life into the economies of remote areas.Like many developing countries, South Africa has countless breadwinners who live and work in urban economic hubs, but have extended families back home in poorer rural areas. There is a high demand for smart banking services that will make sending money back home simpler and less costly.SAinfo reporterWould you like to use this article in your publication or on your website?

South African circumnavigates the globe

first_img8 February 2013South African yachtsman Ralf Dominick has added his name to a prestigious list of only 150 people who have sailed through the Northwest Passage, one of the world’s most severe maritime challenges.The notorious waterway, a sea route through the Arctic Ocean along the northern coast of North America, has historically been considered impassable by many sea explorers.Located 800km north of the Arctic Circle and 1 930km from the North Pole, the route is covered in arctic pack ice for most of the year, which prevents regular shipping in the area.Dominick describes his journey as spectacular, and he has no regret for making it. “I undertook the voyage merely to explore the world on my own terms and had no idea that it would turn out to be of such epic proportions,” he says.“I couldn’t believe that I’d done it. It is a dream come true.”The highlight of his journey was arriving in Nome, Alaska, and realising he got through the passage unscathed.On a boat, built for adventureBefore his odyssey, Dominick was the chief executive of BBD, a software development company he founded with two partners in 1984 in Johannesburg. Today he is the chairman of the board and has a PhD in the management of technology and innovation.His 75 000km voyage of almost three years, circumnavigating the globe, started in February 2010 on board the 53-foot yacht Imvubu (Zulu, meaning hippopotamus). A number of friends accompanied Dominick on various legs of the journey.The skipper describes the yacht as being built for adventure, and with a steel hull and two masts she could easily reach out-of-the-way places. “In car terms she is a comfortable, heavy 4×4 rather than a dainty saloon or a sports car,” he says. “I looked all over the world. I wanted a boat that had no limits in terms of where it could go.”Throughout the journey he wasn’t ever scared, and he says he shares the life philosophy of Captain Joshua Slocum, the first man to sail around the world alone. “His response to people asking him if he was ever scared was no, I feel more alive.”He didn’t plan the trip in too much detail either, except for his crossing through the Northwest Passage. That required good timing and planning the best route as there are numerous ways to get through.“I also met experienced sailors who provided us with a lot of knowledge and we used ice maps from the Canadian Ice Service,” he says.“We took enough provisions to last a year – just in case we got stuck in the ice. You have to be prepared, otherwise you can die.”Adventure of a lifetimeWhat followed in the months leading up to the Northwest Passage crossing, and afterwards, was an adventure of a lifetime to more than 52 of the world’s most spectacular places.These included destinations such as Ascension Island; New York; Grenada; the Tobago Cays, a group of five small uninhabited islands located in the southern Grenadines; Vancouver; the US and Spanish Virgin Islands; Puerto Rico; Southern Bahamas; Washington; Newfoundland; Mexico; French Polynesia; Vanuatu; the Australian Outback and East Timor.“I had a ball,” says Dominick.He has so many memories, but a few stand out as some of his best moments on the voyage.One of them is drifting in front of the Blackstone Glacier in Prince William Sound on a clear and still autumn day. “The incredible fjords, mountains, scenery and hospitable people of Newfoundland and the Alaskan Inside Passage from Cape Spencer to Ketchikan are just spectacular,” he says.“To have been able to witness these scenes for me is just completely humbling.”At Viequez Island on the north eastern Caribbean, he encountered a large bioluminescent bay, considered one of the most spectacular in the world. The luminescence is caused by micro-organisms which glow whenever the water is disturbed, leaving a trail of neon blue.“It looks like fireworks. It was the most amazing thing,” he says.Then between Puerto Rico and the Dominican Republic he managed to get a permit to go to Mona Island. “It was a special place and I was the only boat there.”Here he had an opportunity to see the Mona ground iguana, the largest native terrestrial lizard in Puerto Rico.Dominick had a desire to sail from childhood, and this expedition was a dream come true for the 53-year-old explorer.“I set a goal for myself that at 50 I would like to sail the world,” he says.He was born in Germany, but when he was a child he came out to South Africa with his family, on a boat. His father built fishing trawlers in Luderitz in Namibia.“We lived across from the boat yard and as a kid boats were my playground,” he remembers. “It gave me an appreciation for the sea.”But his love for the sea and sailing is not accidental, he believes it is genetic. All three of his uncles had careers in the maritime industry, and his grandfather worked on a German submarine in World War Two.Planning his next adventureDominick is back on solid ground, and in between connecting with family, friends and business he’s also had to renew his expired driver’s, pilot and TV license.He is already planning his next maritime adventure. Imvubu is back at the Bluff Yacht Club in KwaZulu-Natal where she is undergoing a refit after the hard use over the past three years.She is being prepared for her next voyage in November 2013. The destinations are the Antarctic, Strait of Magellan, the Chile coast, the Panama Canal and Europe.Dominick was named the Royal Natal Yacht Club’s Sailor of the Year for 2012, and through his trip he is also helping to raise the profile of sailing in South Africa and encourage more young people to take up the sport.He was also awarded the Barton Cup by the Ocean Cruising Club, an international body, for the most meritorious ocean race or passage in 2011.“I feel humbled by the accolades that have been heaped on me and wish to express my deepest appreciation to the Ocean Cruising Club, SA Sailing and the Royal Natal Yacht Club,” he says.He had more than 50 books and 1 000 movies on board to while the time away and even though his boat had many modern conveniences, he still missed a few South African comforts.“What I missed the most was biltong and dry wors,” he says.He says circumnavigating the globe has equipped him well for his next journey.“The one lesson I did learn on this trip was the amount of maintenance required to keep a boat going on an extended voyage,” he says. “I am extremely lucky that I didn’t suffer any mayor mishaps along the way.”First published by – get free high-resolution photos and professional feature articles from Brand South Africa’s media service.last_img read more

Two doctors assaulted after patient dies in hospital

first_imgTwo doctors at Bara Hindu Rao Hospital in north Delhi were assaulted by the attendants of a patient who died during treatment on Saturday, the police said. According to Deputy Commissioner of Police (North) Nupur Prasad, a kidney failure patient Rajbala, a resident of Roop Nagar, was admitted to the hospital in a critical condition around 11.40 p.m. on Saturday. Rajbala died during treatment, she said. Things soon went out of hand after the patient’s attendants, including her husband and son, started quarrelling with the doctors on duty. Her son allegedly slapped a doctor and got into a scuffle with the others present. Two doctor — Rajesh Kumar and Pranay — suffered minor injuries. “An FIR has been registered under IPC Sections 353 (assault or criminal force to deter a public servant from discharge of his duty), 332 (voluntarily causing hurt to deter a public servant from his duty) and sections of the Delhi Medicare Service Personnel and Medicare Service Institutions (Prevention of Violence and Damage to Property) Act, 2008,” Ms. Prasad said. Rajbala’s relatives, however, gave a written complaint alleging that she died due to negligence because of delay in treatment by the doctors. “We have sent the body to the mortuary. The post-mortem will be conducted by a medical board to find out if there was any negligence on the part of the doctors. And action, whatsoever, will be taken accordingly. A request for constitution of the medical board is being sent to the Director (Health),” said Ms. Prasad. She said policemen have been deployed at the hospital and the situation was now normal. In June, doctors across the country had gone on strike after a junior doctor was assaulted at a hospital in West Bengal.last_img read more

‘Custodial’ death sparks tension in U.P. town

first_imgTension spread in Pilakhuwa town, Hapur district of Uttar Pradesh, on Monday morning after a man allegedly died in police lock-up of torture. Three policemen, including the Station House Officer, have been suspended.Local sources said Pradeep Tomar (30), a resident of Lakhan village, was picked up by police near the Chhajrasi toll plaza on Sunday for questioning in connection with a murder case. They alleged that he was detained when he was travelling with his wife and son. Late in the night, when his condition deteriorated, he was shifted to the GS Medical College in Pilahuwa, where he died in the early hours of Monday. Meanwhile, a video, purportedly showing Tomar’s backside as completely blue and marks of beating on his arms, has gone viral.Yesh Veer Singh, Superintendent of Police, Hapur, told The Hindu, “On August 30, a half-burnt body of a woman was found in the jungle of Lakhan village. Pradeep was a relative of the deceased. She was the wife of his brother-in-law. During surveillance and investigation, he was found to be a suspect. He developed health complications during questioning and was taken to a local hospital. Later, he was referred to the Meerut Medical College, where he died during treatment.”As the officials didn’t follow the standard operating procedure and didn’t inform their seniors before taking Pradeep into custody, Inspector Yogesh Baliyan, chowki in-charge Ajab Singh and constable Manoj have been suspended. “We are waiting for the post-mortem report before taking further action. A departmental inquiry and a magisterial probe have been ordered,” Mr Singh said. He refused to comment on the video that purportedly shows injury marks on the deceased and the son and wife of Tomar alleging that he was beaten in their presence. “Let’s wait for the post-mortem and inquiry reports. The post-mortem is being video recorded,” added Mr. Singh. Family members and farmer leaders protested in the Meerut Collectorate, demanding murders charges against policemen involved in the case. The PAC (Provincial Armed Constabulary) has been deployed in Pilakhuwa and nearby villages.last_img read more
