Evolutionists Hear Whopping Case of Convergent Evolution

first_img(Visited 97 times, 1 visits today)FacebookTwitterPinterestSave分享0 You won’t believe your ears when you hear what a team of evolutionists claims evolved by “convergent evolution.”The sense of hearing would easily qualify as one of the most complex of senses, not that the others aren’t too.  But to imagine the eardrum, the finely-tuned ossicles of the mammalian middle ear, and the cochlea with its “piano keyboard” of frequency sensors, evolving by chance would surely represent a major challenge to evolution.  Now, however, a team of evolutionists just claimed in Science Magazine a case of “Convergent Evolution Between Insect and Mammalian Audition.”  A katydid in a rainforest has an analogous 3-part mechanism for hearing, despite diverging from the common ancestor back in the Cambrian period, according to the evolutionary timeline.  The abstract states confidently,In mammals, hearing is dependent on three canonical processing stages: (i) an eardrum collecting sound, (ii) a middle ear impedance converter, and (iii) a cochlear frequency analyzer. Here, we show that some insects, such as rainforest katydids, possess equivalent biophysical mechanisms for auditory processing. Although katydid ears are among the smallest in all organisms, these ears perform the crucial stage of air-to-liquid impedance conversion and signal amplification, with the use of a distinct tympanal lever system. Further along the chain of hearing, spectral sound analysis is achieved through dispersive wave propagation across a fluid substrate, as in the mammalian cochlea. Thus, two phylogenetically remote organisms, katydids and mammals, have evolved a series of convergent solutions to common biophysical problems, despite their reliance on very different morphological substrates.Detecting the mechanism of katydid hearing was never possible in such detail before.  The cochlear analogue in the katydid, which they named the “acoustic vesicle,” is so small (600 millionths of a meter), it required x-ray microtomography and other state-of-the-art techniques to elucidate its structure.  Yet in a remarkable diagram, the authors compared the three parts of a human ear and katydid ear side by side, showing how analogous the structures are.Physiologists know that “Cochlear hair cells receive mechanical inputs at specific frequencies, depending on their position along the stiffness gradient of the basilar membrane. This ‘piano keyboard’ mapping, or tonotopic organization, is the canonical mechanism for frequency selectivity in mammals.”  What would they think of a comparable piano keyboard mechanism in the ear of an insect?The authors preached the convergence theme with repetition, stating it six times, including the headline.  For example, they said, “Our results reveal a notable case of convergence, whereby organisms with the most remote phylogenetic histories (such as mammals and katydids), have evolved to hear in a markedly analogous way.”  Ronald R. Hoy chimed right in with the convergence chorus in his Perspectives piece, “Convergent Evolution of Hearing,” in the same issue of Science.  He said that the researchers “show that although the hearing organ of a rainforest insect looks very different from a human ear, it can be divided into the same three functional entities, providing evidence for convergent evolution.”Later, New Scientist jumped on the “convergent evolution” bandwagon without missing a beat.  The article quoted a Cambridge biologist not involved in the study saying, “This is an amazing example of convergent evolution in hearing structures between very distantly related animals.”None of the authors thought to consider this new evidence as a challenge to evolution.   Instead, they treated the convergence concoction as demonstrable fact.  “The parallelism in anatomy and function is the result of convergent evolution between the ears of humans and katydids. It is as surprising as it is remarkable,” Hoy said.One can imagine fairy tales, too, that are surprising and remarkable.  Did evolutionary theory predict this?  No.  This was a surprise.  It was a remarkable surprise.  If you had trouble imagining a blind, aimless process producing a super-sensitive vibrating drum attached to a series of intricate levers that connect to a piano keyboard frequency analysis system, transducing acoustic energy into mechanical energy and then into fluid energy, increasing sensitivity at each step – if you can imagine evolution producing all that once, now imagine it happening twice.This goes to show that evolutionists believe in miracles.  Natural selection is their “Abracadabra” to generate sophisticated systems in living things.  No demonstration is required; no one gets to look behind the curtain and follow the train of random mutations from deaf cell to hearing animal.  If Abracadabra doesn’t work the first time, say it with emphasis, adding Mishikabula, Bippity Boppity Boo.last_img read more

ICT and electronics in South Africa

first_imgThe South African information and communication technologies (ICT) sector is well established and sophisticated.South Africa’s telecom’s infrastructure is 99.9% digital and includes the latest in wireless and satellite communication, the country has the most developed telecoms network in Africa (image: j_cadmus)Brand South Africa reporterThe largest and most advanced in Africa, the local IT industry is characterised by technology leadership, particularly in the field of mobile software and electronic banking services.South African companies are world leaders in pre-payment, revenue management and fraud prevention systems, and in the manufacture of set-top boxes, all exported successfully to the rest of the world.It’s a buoyant sector, with IT spending in 2010 reaching $10,6-billion, according to the South African Electrotechnical Export Council (SAEEC). Together with telecommunications, it generates an estimated $29-billion in revenues, R10.3-billion of which comes from IT.InnovationSouth African software developers are recognised for their innovation, production and cost efficiency – and are backed by sturdy local infrastructure, as well as government support. For example, the government amended the Income Tax Act in efforts to stimulate local innovation and create jobs: software developers can now claim back 150% of research and development (R&D) expenses against tax. There are around 1 000 software development firms in South Africa.TelecomsWith a network that is 99.9% digital and includes the latest in wireless and satellite communication, the country has the most developed telecoms network in Africa. Financial assistance is also available from the Industrial Development Corporation, which aims to promote technology development. The Support Programme for Industrial Innovation (SPII) supports companies engaged in the development of innovative or creative products, for example.Several international corporates, recognised as leaders in the IT sector, operate subsidiaries from South Africa, including IBM, Unisys, Microsoft, Intel, Systems Application Protocol (SAP), Dell, Novell and Compaq.OpportunityTesting and piloting systems and applications are growing businesses in South Africa, with the diversity of the local market, first world know-how in business and a developing country environment making it an ideal test lab for new innovations. In 2010/11, Gartner, the international research group, ranked South Africa within the global top 30 software development outsourcing destinations.OutsourcingSouth Africa is a favoured international location for business process outsourcing. Investment opportunities lie in the roll-out of wireless networks and technologies, and in the local assembly of green-energy technologies for electronic components and subassemblies.Other opportunities include the development of access-control systems and security equipment, automotive electronic subsystems, systems and software development in the banking and financial services sector, silicon processing for fibre optics, integrated circuits and solar cells. There are also significant opportunities for the export of hardware and associated services, as well as software and peripherals.Export growth and internationalisation of South African companies is supported by the Department of Trade and Industry via the Electrotechnical Export Council (SAEEC). South Africa’s ICT infrastructure is among the most developed in Africa.

Men’s 40’s Attend Youth Festival

first_imgRain failed to dampen the spirits of the school students, who were divided into groups and coached by Australia, Guernsey, Niue, France and Singapore. The weather didn’t stop the children’s opening ceremony, walking into the venue with their adopted nation’s flag and sign, before doing a march past with the athletes and donning a shirt in their countries’ colours. The children were then put through their paces by their respective country, with the adopted Australians learning plenty of new skills and rules about the game. The Men’s 40’s then gave the teams a demonstration of how to put all of their skills together on the field and they then got to put all their newfound skills into practice, having games against the other countries’ children. And it wasn’t just the kids that were having a blast, with the player’s enjoying the opportunity, as well as giving Australia a few new fans as well!Stay tuned to the TFA YouTube channel for all of the highlights from the Youth Festival. www.youtube.com/touchfootballauslast_img read more

Professor Green Joins Fight Against Male Suicide

first_imgRapper and singer/songwriter Professor Green has been named as the new patron of anti-suicide charity CALM.Two major men’s brands, Lynx and Topman, have also committed to lend their support to the campaign to fight male suicide.Writer and comedian, David Baddiel, who is stepping down as Patron and handing over the baton to Professor Green, said, “I’m very honoured to have been the patron of CALM for the last seven years. Over that time, it’s done a brilliant job of raising public consciousness about the overwhelming problem of male suicide, and of providing a resource and lifeline for men who are depressed and feel they have no-one to talk to. I’d also like to welcome Professor Green to the Patron post. I know he’ll have a great time working with this amazing charity.”Professor Green said,“We need to get the message out to young men that talking and asking for help when things go bad is what everyone should be able to do, whatever their gender, and it’s fantastic to see brands like Lynx and Topman put their weight behind CALM and help create the cultural change which will help save lives.”Lynx has committed to support CALM’s helpline that is currently taking almost 5,000 calls a month. Topman will be distributing award-winning men’s magazine, CALMzine, in their key stores across the UK.Jane Powell, CALM CEO emphasises: “While mental health has risen up the agenda urgent funding is still required as more money needs to be dedicated to this service in the years to come, but with all the will in the world that won’t create the social change needed to tackle male suicide. Having Professor Green and brands like Lynx and Topman help us share the message that it’s ok to talk, however, will help us foment the cultural change we need to finally tackle this issue.“On behalf of everyone at CALM, I would like to thank David Baddiel for his work and commitment over the last seven years. His support and passion for this cause has been unswerving and his dedication has helped us to progress our campaign. We now look forward to working with Professor Green to continue this work.”Find out more about CALM here.last_img read more

Ohio State Oregon agree to homeandhome series in 2020 2021

Chalk up another rematch for the Ohio State football team. Almost two weeks after finalizing an agreement to play Texas in the coming years, the Buckeyes secured another home-and-home series with Oregon for the 2020 and 2021 seasons, the athletic department announced Tuesday. “Oregon has developed into one of the premier football programs in the (Football Bowl Subdivision),” OSU athletic director Gene Smith said in a released statement. “We are excited to add them to our future slate of games.” The Buckeyes are slated to travel to Eugene, Ore., for a Sept. 12, 2020, contest before hosting Oregon on Sept. 11, 2021, in Columbus. Ducks’ athletics director Rob Mullens said OSU “provides another major conference opponent” for the future. “The Pac-12 and Big Ten have enjoyed a long-standing relationship, so the opportunity to add another Big Ten opponent was attractive, Mullens said in a released statement. “We have two of the most passionate fan bases in college football and the atmosphere at both Ohio Stadium and Autzen Stadium are among the best in college football.” Oregon football coach Chip Kelly said he shares a similar mindset. “This will be a great opportunity for our fans to be a part of an intersectional battle that has not taken place in Eugene very often,” Kelly said in a released statement. “I’ve always been a proponent of playing the highest level of competition possible. I’m a firm believer that you make yourself better when pushed by the level of your competition.” While the teams have only met eight times, it’s been less than three years since OSU defeated the Ducks in the 2010 Rose Bowl, 26-17. In fact, the Buckeyes are 8-0 against Oregon all-time. On Oct. 10, OSU and Texas agreed to play in Austin in 2022 and Columbus in 2023. The contest against the Longhorns is the first since the 2009 Tostitos Fiesta Bowl, which saw Texas top OSU, 24-21. The Buckeyes announced the completion of their non-conference schedule for 2016 season Tuesday after home games against Tulsa on Sept. 10 and Central Michigan on Sept. 24 were finalized. Rounding out the Buckeyes’ non-conference schedule that year will be Bowling Green (Sept. 3) and Oklahoma (Sept. 17). read more

Roberto Martinez impressed by Hazards performance

first_imgEden Hazard has again proven his worth to the Belgium team in their friendly game against Scotland.His coach Roberto Martinez was largely impressed by Hazard’s performance and he praised the player’s role in setting the example as the captain of the team.In the 4-0 win against Scotland, Hazard had lead the attack on the opponent until he was substituted on the 56th minute of the game.Hazard scored after Romelu Lukaku had opened the scoreline in favour of his team. He also made an assist for Michy Batshuayi.FourFourTwo reports Martinez’s response after he was asked whether the Chelsea star man had worked too hard on himself ahead of the friendly: “I don’t see that as a negative. He’s in a good moment and he’s carried on from where he was in the World Cup.James Rodriguez, Real MadridZidane hails ‘quality’ James Rodriguez after Real Madrid’s win Andrew Smyth – September 14, 2019 Zinedine Zidane reserved special praise for James Rodriguez after his starring role in Real Madrid’s 3-2 win over Levante.“When you’re a captain, you have to set the standard in that sort of manner. It’s dangerous when you go into a football match not giving everything.“Hazard is giving what you want from a captain. I don’t think there was anything wrong with him trying to find the right space and drag people out.”last_img read more

Guardiola Man City dont deserve quadruple pressure

first_imgManager Pep Guardiola believes it’s unfair to put pressure on Manchester City winning the quadruple at this stage of the season.On the back of winning a domestic double last season, City are potentially looking at exceeding that this term as they remain firmly in the hunt in all competitions.Guardiola’s side lead the Premier League on goal difference from Liverpool and are in a strong position to progress from their last-16 tie with Schalke 04 in the Champions League after winning the first leg 3-2 in Germany last Wednesday.City have also progressed to the FA Cup quarter-finals and will be looking to win the Carabao Cup for the second season in a row ahead of today’s final against Chelsea at Wembley.But Guardiola, who has enjoyed a stellar managerial career with spells at Barcelona and Bayern Munich, insists it’s too early to bill City as potential quadruple winners.“You can’t win anything if you don’t believe: ‘we are strong enough to compete everywhere’,” said Guardiola on the club website.“In February, it is impossible to talk about [the quadruple]. Ask me the question in April or May. I will not lie to you.“Kevin [De Bruyne] said it perfectly at his press conference in Germany: the next target is the next game.“You are trying to sell some illusion. How many times has an English team won four titles? Don’t put that pressure on our shoulders – we don’t deserve it.“Look at the legacy Sir Alex Ferguson left – incredible – but he never did it. Look how many Champions League titles Liverpool have in their pocket, but they never did it. “In May, we will see. If we don’t win four titles, then everyone will say ‘Manchester City have failed!’ but don’t do that to us.Premier LeaguePremier League Betting: Match-day 5 Stuart Heath – September 14, 2019 Going into the Premier League’s match-day five with a gap already beginning to form at the top of the league. We will take a…“In recent weeks, I have said that the most important thing after achieving what we achieved last season is that we are still fighting in all competitions. It means a lot to me.”The Catalan coach admits a win for local rivals Manchester United against Liverpool in today’s showdown at Old Trafford would be beneficial for his City team.But winning today’s Carabao Cup final against Chelsea is the priority.Guardiola added: “Once you are in a final, that becomes the most important game.“The Premier League is the most important competition – and then the Champions League and FA Cup – but the Carabao Cup is now the most important game by far.“Of course, it would be good for us if United got a result – but we have a Final! “Winning trophies always helps us to grow as a Club. We have to arrive in the last stages of all titles – that is what I count as a big Club.“We are in the final and Chelsea have played more Finals than us. It will be an incredibly tough game for them and for us.“Of course, we want to win!”The Carabao Cup final between City and Chelsea will begin at 5:30 PM (CET) at Wembley today.GELSENKIRCHEN, GERMANY – FEBRUARY 20: Players of Manchester City line up prior to the UEFA Champions League Round of 16 First Leg match between FC Schalke 04 and Manchester City at Veltins-Arena on February 20, 2019 in Gelsenkirchen, Germany.
