Whale of a Batty Tale on Sonar Evolution

first_imgHow did two animals completely different in size and ancestry, living in very different environments, arrive at the same complex sensing mechanism?Bats and whales are both mammals, but they could hardly be more different.  A press release from the University of Southern Denmark describes the extremes,Sperm whales weigh up to 50 tons, and the smallest bat barely reaches a gram. Nevertheless, the two species share the same success story: They both have developed the ability to use echolocation – a biological sonar – for hunting. Now Danish researchers show that the biosonar of toothed whales and bats share surprisingly many similarities – even though they live in very different environments and vary extremely in size.The article describes echolocation as “one of Nature’s extremely successful specializations,” then asks, “why have such different animals as whales and bats both developed the same technique?”  The answer cannot be relationship, because (according to the evolutionary scenario), their common ancestors diverged 200 million years ago. Both bats and whales “developed the ability” long after they split onto separate branches of the mammalian tree.And yet the sounds of a tiny bat and a huge whale are “surprisingly similar,” the researchers found.  Despite the former flying in air and the latter swimming in water, both use sounds in the 10-200 kHz range for echolocation.  In addition, they both employ a similar hunting strategy:In the last part of the hunting phase, when they approach their prey both toothed whales and bats emit a series of buzzing sounds: Weak and short sound pulses at very short intervals – similar to strobe lights. It is a very complex mechanism that scientists do not yet fully understand. The animals control very carefully when they emit sounds and when they listen for echoes – and they adjust this exactly to their own and the prey’s speed. If they emit the buzzing sounds too fast they do not have time to listen for the echoes. If they do it too slowly they risk hitting obstacles on the fly.There must be an explanation for the remarkable similarity of biosonar – which coordinates mouth, ears, brain and behavior – in such very different animals.  The press release, without hesitation, offered one up:The answer lies in convergent evolution – when almost identical features or developments happen in different species. Through evolution both bats and toothed whales have developed the same functional characteristics.What more needs to be said?  A bat is a bat and that’s that.  A whale is a whale and there’s our tale.Incidentally, European evolutionists publishing in Nature found pervasive “convergent evolution” in echolocating mammals all the way down to the genes.  The Editor’s Summary waffles between confidence and surprise:Convergent evolution, through which similar traits evolve in unrelated lineages, is a familiar demonstration of the power of natural selection. These traits are usually viewed as representing alternate evolutionary solutions involving different sets of genes, but that view is challenged by a study of echolocating mammals. Analysis of the genomic sequences in 22 echolocating species, including four new bat genomes, reveals that convergence is not a rare process restricted to a handful of loci but is widespread, continuously distributed and commonly driven by natural selection acting on a small number of sites per locus. Convergence is particularly strong in genes linked to hearing or deafness, but surprisingly, also to vision.The authors used the words “convergence” or “convergent” a shocking 122 times in their paper, ending with more surprise: “the importance of this mode of molecular evolutionary change is relatively underappreciated, and is under-exploited in seeking to understand the genetic basis of complex traits such as echolocation.”  If they are still seeking to understand it, it implies they do not understand it.Batty evolution:  Speaking of bats, five European evolutionists presumed to describe their evolutionary relationships.  Writing in Current Biology, they admitted in the first paragraph that “the exact evolutionary relationship of bats to their closest mammalian relatives is poorly understood due to their unique morphological features associated with flight, a lack of intermediate forms, and a poor fossil record.” This sounds very similar to what another international team declared in 2005 (1/28/05).By filling in those gaps with “phylogenetic analyses” (essentially, DNA comparisons), they drew up their tree diagrams showing where bats fit with other mammals, including humans.  Boasting about their achievement, they invoked “convergent evolution” again in a rather extraordinary manner:… this study provides the most concrete evidence to date toward resolving the long-standing debate regarding bat evolutionary history. Our results further emphasize the extraordinary phenotypic convergence seen across echolocating members of the two suborders, including the possible independent origin of laryngeal echolocation itself, a hypothesis supported by several studies of molecular evolution of sensory genes….They never did mention fossils again.  One thing creationist Dr. Duane Gish liked to point out in his hundreds of debates with evolutionists on college campuses is that the first fossil bat was 100% bat (2/16/08).So there’s your answer.  Take it or leave it.  Bats and whales “developed” these complex systems by “convergent evolution.”  How can evolutionists say such things with a straight face?  It’s because their faces are not straight.  The straitjackets they wear (100% DODO synthetic) contort their faces into crooked shapes that cause them to emit strange buzzes and squeaks as they try to say “Hail Darwin!”.  The squeaks bounce off the walls of the Darwin echo chamber in which they imprison themselves.  The sounds reinforce one another as they re-enter the ears, amplifying the illusions of understanding for which they hunt – a demonstration of convergent evillusion.

Release Date for Lightworks Mac Public Beta

first_imgLightworks has officially unveiled a date to release it’s public beta for Mac.If you aren’t very familiar with Lightworks you’re in good company. Lightworks is currently a Windows and Linux based video editing application, and while it’s not as popular as some other editing platforms such as Apple, Adobe, or Avid, it has a 20 year history.Big budget editors such as Tariq Anwar of The King’s Speech and Jill Bilcock of Road to Perdition have used Lightworks as their NLE of choice for years. With Red native format supporting, exporting in the background, multicam editing, and project sharing for editing in groups, Lightworks is aiming to be a contender against the other popular NLEs.Lightworks will boast the only tri-platform support (Windows, Mac, and Linux) but as of right now you can only use it on a Window’s and PC machine. That is all scheduled to change very soon. In an interview with RedSharkNews, Matt Sandford, the Global Product Manager for Lightworks stated:“The most common question we get asked is when will Lightworks be available on Mac? Well, we are pleased at last to say with confidence that the Mac Public Beta will begin on the 11th of June 2014.Before that though there will be a short Alpha program to a dedicated select team of users. These are users that have requested Alpha access in the past and are keen to help make sure that the Mac version is on track where it needs to be. This is the exact same process we did with the Linux version. The Mac version has been in existence for some time, so is already very stable, but because reliability is essential we are looking to test this intensively from Alpha through to Beta”The best part is Lightworks is free with an unlimited trial period. The only catch is if you want to export a file format larger than 720p you must pay for the “Pro” software which is available through a membership (7.99 a month or 79.99 a year) or outright purchase for 279.99 (which is much cheaper than any other major editing applications).You can download Lightworks from their website. Be on the lookout for the upcoming Mac release!Do you currently use Lightworks? Looking forward to the Mac release?Share in the comments below.last_img read more

Anwar disapproves of Sidhu’s Muslim pitch

first_imgSenior Congress leader Tariq Anwar on Wednesday disapproved of Navjot Singh Sidhus appeal to Muslims to defeat BJP and said he would have stopped the Punjab Minister from doing so had he been present at the rally held in his Lok Sabha constituency of Katihar. “I have always held the view that votes must never be sought in the name of religion and caste. This has also been the policy of the Congress party. I do not approve of what Sidhu has uttered. I would request the party leadership to take note for suitable action,” Mr. Anwar said in a statement.Mr. Sidhu, against whom an FIR has been lodged at Katihar in Bihar for violating the model code of conduct, made the controversial statement at a rally in Barsoi police station area of the district on Monday. The matter came to light when a video footage of his utterances were beamed on TV news channels on Tuesday wherein he could be heard asking Muslims, who have a sizeable presence in Katihar, to be wary of Asaduddin Owaisis AIMIM alleging that it was being propped up by the BJP. He also urged the Muslim voters to unite in favor of the Congress candidate Tariq Anwar and drawing an analogy from cricket, remarked Modi will go for a six if you do so. “I was not present at the Barsoi rally. Had I been there, I would have immediately stood up and expressed my disapproval of the way he was canvassing for me,” Mr. Anwar clarified in his statement. The episode in Bihar came close on the heels of the Election Commission taking punitive action Yogi Adityanath and Mayawati for violating the poll code of conduct.last_img read more

Asian Games: Rowers scoop two silver as India pick up three medals

first_imgThe rowers provided an unexpected boost to India’s medal hunt in the 16th Asian Games with two silver medals but poor form continued to haunt the fancied shooters with Gagang Narang flopping yet again on the sixth day of competitions in Guangzhou on Thursday. MEDAL TALLYApart from the silver-winning feat of the rowers, shooter Vijay Kumar bagged a bronze medal and Paramjeet Samota assured himself of at least a bronze after punching his way into the semifinals of super heavyweight on yet another mediocre day for India’s large contingent.With the addition of two silvers and a bronze, India took their medals tally to one gold, seven silver and eight bronze but the failure to win the coveted gold has resulted in a continuous slide in the position on the table in the last few days.Tennis star Sania Mirza had a trouble-free day as she sailed into the pre-quarterfinals of the women’s singles with a straight-set demolition of Hong Kong’s Chan Wing Yau Venise while the racqueters got off to a good start with both men’s and women’s team progressing to the quarterfinals of the squash singles event.On the gloomier side, the Indian challenge in table tennis ended with Achanta Sharath Kamal and Anthony Amalraj bowing out in the pre quarterfinals of the men’s singles event. It was a similar story in men’s singles badminton with Arvind Bhatt crashing out out in the pre-quarterfinals.It was the men’s rowing four team of Anil Kumar, Saji Thomas, Ranjit Singh and Jenil Krishnan which began the silver collection as they completed the distance of 2000m in 6:16.79, behind China (6:06.40). Uzbekistan won bronze with a timing of 6:22.70.advertisementIn the men’s lightweight four event final, the Indian quartet of Lokesh Kumar, Manjeet Singh, Rajesh Kumar Yadav and Satish Joshi finished second with a timing of 6:13.32, behind Japan who clocked 6:10.14. Hong Kong won the bronze, clocking 6:14.84.After three barren days at the Aoti shooting range, Vijay Kumar notched up his second and India’s fifth medal in shooting by bagging a bronze in men’s 25m center fire pistol but Commonwealth Games hero Narang missed out on a bronze by a whisker in 50m rifle 3 positions.Vijay shot 583 (290+293) to finish third behind South Korea’s Park Byung Taek who scored 586 (290+296) and Liu Yadong of China who fired 585 (290+295).last_img read more

No barrier to probe atrocities against Rohingyas ICC team

first_imgRohingya refugee carries an elderly man at the Palongkhali refugee camp near Cox`s Bazar. Reuters file photoThe Office of the Prosecutor, International Criminal Court (ICC) does not see any barrier in carrying out “preliminary examination” and subsequent investigation into alleged atrocities committed against Rohingyas by the Myanmar military though Myanmar is not a State Party to the Rome Statute, reports UNB.”The ICC process is not about Myanmar, it’s not about Myanmar as a state. It’s about individual’s criminal responsibility,” ICC’s director of Jurisdiction, Complementarity and Cooperation Division Phakiso Mochochoko told reporters at a city hotel on Monday evening.The delegation from the Office of the Prosecutor of the International Criminal Court (ICC) is set to leave Dhaka on Tuesday.Explaining further about individual criminal responsibility, he said it is all about the people who are responsible, who have given instructions, who have commanded and the people who did all other things and facilitated to commit these alleged crimes.Mochochoko said it will not in any way be a hindrance despite the fact that Myanmar is not a State Party and will not cooperate with the Office of the Prosecutor into this.Expecting cooperation from everyone, he said Myanmar’s noncooperation might present a little bit of challenge for them in terms of investigation but there is no barrier to go ahead without cooperation from Myanmar.Mochochoko said this is not the first time they engaged in this kind of process but they had got many other situations where they had been engaged. “Almost all of them have come to fruition – in one way or another.”He said the independent and impartial preliminary examination of the situation in Bangladesh/Myanmar is going on and will follow its course.”A preliminary examination is not an investigation, but an assessment of the Rome Statute criteria to decide whether an investigation into the situation at hand is warranted,” he said.Therefore, during their Bangladesh mission that ended on Monday, he said the delegation did not collect any evidence or perform any other investigative activities as it is the standard practice of the Office.Meanwhile, they had interactions with relevant ministers and meetings with representatives of international organisations, and visited Rohingya camps.Earlier, the ICC wanted to know Bangladesh’s opinion on whether The Hague-based court has the jurisdiction to run a case on atrocities against Rohingyas.The pretrial chamber of the ICC sent a letter to Bangladesh in this regard on 7 May 2018 seeking opinion on three specific matters by June 11, either publicly or confidentially.Bangladesh responded to the request of the International Criminal Court (ICC) on Rohingya issue, as the country is seeking a “sustainable solution” to the crisis.last_img
