Powered by Firework Amit Panghal, the 24-year-old boxing champ made India proud when he won the silver medal in the World Championships. In an interview the young boxer opened up about his preparation for the upcoming Asian Olympic quantifier that is to be held in Wuhan, China. The boxer seems confident that next year India can expect 2 gold medals from the Olympics 2020 in the boxing category. The Olympic games is to be held next year in Tokyo. After boxers like Vijender Singh and Mary Kom brought medals home, the nation’s hope increased.Advertisement “We will go into the Tokyo Olympics with an aim to win at least two gold medals. We can win more but at least two gold medals can be expected from Indian boxers at the Tokyo Oympics.”Advertisement India has focused more on the training of boxers after winning medals in the country. Amit believes, the boxers have worked hard on their strength and technique and will give tough competition to other boxers in the game.“Our performance in boxing in the recent times has improved by leaps and bounds. We have won many gold medals, whether it be at the Commonwealth Games or Asian Championships, or World Championships. ”Advertisement Indian boxers have not yet brought home a gold medal. Previously, Mary Kom and Vijender Singh both won bronze medals. The former won it at the London Games 2012 and the latter won it at the Beijing Games 2008. By next year, India may already have a gold medalist in boxing.Amit also shared his opinion on the clash between Mary Kom and Nikhat Zareen.“Mary Kom is a star in India boxing. According to me, it doesn’t matter for Mary Kom if there are trials or not because she doesn’t need to prove she is the best as she has already proved that. But, even if the trials do take place, I don’t think so that Mary Kom should be worried about anything as she can handle these things quite easily.”The boxing champ is currently a part of the Gujarat Giants and will be taking part in the Big Bout Indian Boxing League apart from the Olympics.Mary Kom will not compete against Nikhat Zareen in boxing league but Olympics trial bout still on for December 27 Predictions On How The Manchester United Will Finish The Season Advertisement
Djokovic brought world No 1 Murray’s 28-match winning streak to an end on Saturday to retain his Doha title in a three-set thriller.The Serb star won 6-3 5-7 6-4 in a high-quality, action-packed match between the two best players in the world lasting almost three hours.It was Djokovic’s 25th career victory over Murray and he laid down an early-season marker against his great British rival, before the Australian Open later this month.In what was their first meeting since Murray beat the Serb at the ATP World Tour Finals in London in November, snatching Djokovic’s number one ranking in the process, Sky Sports Tennis expert Croft felt both men dragged each other to the limits.”It was one of the most extraordinary matches I’ve witnessed in terms of its level,” Croft told Sky Sports. “They have such an incredibly tense rivalry anyway, but they seemed to bring out the best of each other in this match.”I’m sure that when they look back on their careers they’re both going to thank each other for pushing themselves to new heights.”I have to say that the level was breathtakingly brilliant. If that’s a taster for what we’ve got in store for 2017, we’re in for a special rollercoaster ride, I think.”Croft expects to see Murray, who lost Melbourne finals in 2010, 2011, 2013, 2015 and 2016, four of those to Djokovic, take on his arch-enemy in more big finals this year.”It’s highly likely we’ll see them in many finals, she admitted. “Their level is so high, but it’s also exciting to see Stan Wawrinka, Juan Martin del Potro, Grigor Dimitrov, Dominic Thiem and Alexander Zverev in the mix too. And you now also have the ‘big four’ back with Roger Federer and Rafa Nadal in the frame again – it makes for such an exciting year.”Of course Andy will be disappointed not to have won in Doha, but I’m sure he was never going to underestimate Novak Djokovic. Losses always sharpen you up.”I saw the line ‘Pass the Parcel’ in one article, and I thought, ‘what a great headline’. It feels like you don’t know whether these two are going to be batting backwards and forwards with a lot of intense pressure on that number one status this year.””They’re going to keep pushing each other,” said the former British No 1. “I think that the tennis was just absolutely phenomenal. It was a privilege to sit down and watch them play that kind of tennis.”It’s like them saying ‘wow’ – ‘is this what it’s going to be like for the rest of the year?’ when they shook hands at the net.”They know what they’re up against when they walk out onto court and they both rise to the challenge. It was great to see Novak back playing to such a high level at the beginning of the year. I believe he has sent out a very clear message to the rest of the Tour, saying ‘don’t write me off just yet’.Croft also believes the Scot, who received a knighthood in the New Year’s Honours, couldn’t be more deserving, adding: “It’s fantastic news. It shows everything that he put into his career has paid off and been appreciated.”Check our game-by-game updates from Andy Murray’s matches at the 2017 Australian Open by following our blog on skysports.com/tennis, our app for mobile devices and iPad or our Twitter account @skysportstennis.
– says it is not serious about changing sameBy Samuel SukhnandanGovernment’s aversion to changing local laws in relation to sentencing of persons found with small quantities of marijuana has not gone unnoticed. In fact, the Society of Marijuana Advocates for Reform and Treatment (SMART) has accused the Government of ‘pussyfooting’ on the issue.SMART steering committee member Nicole Cole told Guyana Times on Sunday that Government is not serious about changing the laws, as there had been enough time to get things in order, but there is detected a clear reluctance. She said, “They’re playing Russian Roulette with the local Rastafari community.”Cole charged that the Coalition had given its word that it would review the Narcotics Law. The Rastafarian community had tied the review of the law to its political votes when the Coalition had promised to do so. She said the APNU is currently pussy-footing and the AFC has a motion before the National Assembly; but, she said, “Even that motion needs to be tweaked further to free Rastafari from Babylon chains!”For almost three years, the AFC has still not managed to find support from the APNU to support the motion in the name of AFC parliamentarian Michael Carrington to move the first reading of the Narcotics Drug and Psychotropic Substances (Control) (Amendment) Bill. The motion to have the first reading of the Bill was tabled since December 10, 2015. The Bill itself has not been made public.Former AFC Chairman Nigel Hughes, with the help of Attorney Mark Waldron, had drafted the bill, which seeks to soften the penalties for marijuana possession. That draft bill stipulates that persons who are found in possession of the drug for personal use would be required to pay a fine of $10,000, or perform community service for a period of time, something that is being widely supported.Cole recalled the Rastafari community meeting with Attorney General Basil Williams sometime in 2016 to pursue the review of the law. The community has also met with the Caribbean Community (CARICOM) Cannabis Commission which is reviewing the law across the Caribbean. The SMART steering committee member said Guyana should take note of what is happening in other Caribbean territories in relation to this issue, particularly Jamaica and Antigua and Barbuda.Recently, the Government of Antigua and Barbuda formally apologized before the Organization of American States (OAS) on discrimination against the Rastafarian community, hoping to improve relations with the religious group. The Government there has also committed to enhancing the rights of that minority group, with hopeSMART steering committee member Nicole Coleto review local marijuana laws.Meanwhile, in Jamaica, while marijuana is illegal, possession of small amounts was reduced to a petty offense in 2015. The country has also established a licensing agency to regulate a lawful medical cannabis industry on the island. Cultivation of five or fewer plants on any premises is also permitted in Jamaica, where the drug has long been culturally entrenched, although illegal.FightGiven the slow pace at which Government is treating this issue, Cole told Guyana Times, SMART and other Rastafarian groups will not give up, but will continue to fight to ensure that some serious attention is given to that matter, so that Guyana could follow in the footsteps of other countries.Cole explained that it is Government’s ‘flippant attitude’ that occasioned the recent march by the Rastafari community, calling for their rights to use what they described as the holy sacrament (marijuana) to be recognized. What occurred in 2018 could continue in the coming months, she warned.“We will never give up the fight to be recognized as a legitimate religious entity, because those rights are enshrined in Art 146 in the Constitution of Guyana, which this Government is denying. We’ve been ostracized, victimized, vilified, and treated as persona non grata by successive Governments because of our use of the holy sacrament. We are the “dregs of society.”On Thursday, Opposition Leader Bharrat Jagdeo announced his support for custodial sentences for small quantities of marijuana to be removed from the law books in their entirety, but maintained that he is not in favour of the legalisation of marijuana for commercial purposes.Jagdeo reminded that the People’s Progressive Party (PPP) has made a commitment to support a ‘conscience vote’ should the matter come up for a vote in the National Assembly.“To send somebody — a young person or even an older person — to jail for less than a quarter ounce of marijuana, for three years, when we have people who are traffickers, and we have people growing large quantities of marijuana, because they have money they get off from the system,” he explained.The former President said he is not opposed to having them face some penalty, but he would recommend alternative or non-custodial sentencing, such as: community work and rehabilitation. Jagdeo noted that it was not a contentious issue as that of the death penalty, and could be resolved.
REDLANDS – It wasn’t really a walk in the park for the Redlands girls water polo team. It was more like a leisurely swim in the lake. “We were able to play a lot of different people and work on some things,” Redlands coach Matt Fry said. “But we didn’t get exactly what we wanted. We weren’t executing our front-court offense. All of our goals were coming in transition.” Brooke Vessey led Redlands (21-7) with six goals, Sharon Dyer had five, Doris Tran four and Emily Haws three. Also chipping in for the Terriers were Danielle Adams, Ariel Lovett and Carly Miller with two goals each and Stacey Triche with one. Celestina Hudson scored Norco’s only goal. It was going to be a tough challenge for Norco regardless of the situation, but things really didn’t fall into place for the Cougars under sunny skies at Redlands East Valley High School. To begin with, coach Cindy Robinson was attending a funeral and could not make the match, assistant coach Charlie Holderman said. Also, the Cougars were elevated from D6 to D5 just last year and have just one returning senior, Bethie Conlan, on their roster. The Terriers overwhelmed Norco 25-1 on Thursday in a CIF-Southern Section Division V playoff opener. As far as the Terriers were concerned, it was a decent tune-up, one to work on a few fundamentals and strategies before the real challenges arise. “It was a tough match,” Holderman said. “Redlands is really good. I think they’re going to do well in CIF.” The Terriers are ranked third in CIF, behind Murrieta Valley and Corona Santiago. The Citrus Belt League champs have played Santiago twice, splitting the matches. “I think we have a good shot at making the finals,” Fry said. Redlands will play the winner of Thursday’s Temescal Canyon vs. Montclair match on Tuesday in the quarterfinals. DIVISION III Chino Hills 6, Downey 5 Amy Moore and Bryce Winton each scored two goals as the Huskies (26-5) slipped past the Cougars in the first round. Chino Hills advances to the second round for the first time since 2004. Senior Nicole Concialdi had seven saves in the victory for Chino Hills, which plays host to Arlington on Tuesday at Ayala. 160Want local news?Sign up for the Localist and stay informed Something went wrong.

ANTELOPE VALLEY (5-2) at LANCASTER (6-2), 7 p.m. Key stat: 3. Ways Antelope Valley WR/DB D’Andre Goodwin has scored touchdowns this season. He has scored on a run, a reception and an interception return. He leads the Antelopes with four interceptions. Outlook: Antelope Valley (3-0 Golden) can clinch the Golden League title with a victory. Lancaster must win to keep its title hopes alive and keep its playoff hopes strong after an upset loss to Highland last week. Recent history is on Lancaster’s side. The Eagles (2-1) have beaten A.V. the past two meetings, 26-21 in 2003 and 10-3 last season. Antelope Valley RB Andre Crenshaw will play after missing two games with a calf injury. Lancaster is led by senior RBs Tony Jackson and Josh Gaines. Key stat: 5. Number of players who scored touchdowns in Littlerock’s 50-3 rout of Knight. Luthur Dillon, who leads the Lobos with five touchdowns, scored three. Outlook: Quartz Hill (1-2) nearly upset first-place Antelope Valley last week. The Rebels were driving for what could have been the winning touchdown in the closing minutes, but A.V. DB D’Andre Goodwin ended the threat with an end-zone interception. Littlerock (1-3) has shown offensive potential the past three weeks, scoring 81 points against Palmdale, Antelope Valley and Knight. Before that, Littlerock had reached the end zone once in three games. ROSAMOND (5-2) at FRAZIER MOUNTAIN of Lebec (1-6), 7 p.m. Outlook: Rosamond (2-0 HDC) is No. 4 in Southern Section Div. XII and has outscored opponents by 98 points during a four-game winning streak. The Roadrunners are coming off a big 34-0 High Desert League victory over Mojave, which they hadn’t beaten since they last won a league championship, in 1999. Rosamond can’t look past Frazier Mountain (0-2) toward next week’s game against Bishop, which figures to decide the league title. dtpost!VASQUEZ (6-1) at SANTA CLARA of Oxnard (1-6), 7:30 p.m. Outlook: Freelance Vasquez looks to get back on track after last week’s 28-0 loss to Boron. Injuries to several players contributed to the Mustangs’ first setback, and they dropped from third to sixth in the Southern Section Div. XII rankings. Vasquez figures to put up big numbers against Santa Clara, which it thrashed 50-0 last season. MONTCLAIR PREP of Panorama City (0-6) vs. PARACLETE (1-6), Saturday, 7:30 p.m. at Antelope Valley College Outlook: Times have changed since these teams met in the 2000 and 2001 Div.

SANTA CLARA — Jalen Hurd became the second wide receiver drafted by the 49ers on Friday, joining Deebo Samuel as a new (and presumably improved) options for quarterback Jimmy Garoppolo.But Hurd is not just viewed as a wide receiver by the 49ers. Hurd’s background as a star running back and his potential to perhaps line up some at tight end has coach Kyle Shanahan salivating over the possibilities.“We plan on him coming in as a wide receiver but I don’t think that’s where it stops,” Shanahan …
Here are a dozen notable news reports from the past week bearing on evolution, design and amazing discoveries.Red rover, rat rover: Live Science posted a cool video about research lab at Northwestern University that is imitating rats’ whiskers to improve robot sensing. Rat whiskers are very sensitive. Neurons in the base of the follicle convey a great deal of information to the brain, even in the dark. The researchers envision this tactile technology on Mars rovers someday.Spiderman glue: We’ve heard about efforts to duplicate spider silk, that ideal substance stronger than steel, but what about the glue that coats the silk strands? PhysOrg and Science Daily reported that scientists in Wyoming are trying to imitate that, too. Why? They could help technology “advance toward a new generation of biobased adhesives and glues – ‘green’ glues that replace existing petroleum-based products for a range of uses.” Spider web glue “is among the world’s strongest biological glues,” the article said. That’s impressive considering the strength of barnacle adhesion. Speaking of spiders, the largest orb-weaving spider was discovered in Madagascar, reported Science Daily. The picture shows a 1.5-inch big momma with legs 5 inches long sitting in her web over a meter across. Images of Shelob in Lord of the Rings come to mind. Another discovery reported by all the science news outlets including Science Daily and National Geographic News was a “surreal” critter that is the first known spider to feed primarily on plant material instead of animal tissue. This new species that New Scientist called the “Gandhi” of spiders is “the only known vegetarian out of some 40,000 spider species.” Evolutionists attributed the origin of this herbivorous spider to “co-evolution” and “social evolution.”The Sting for health: Imagine skin cream loaded with stinging cells from jellyfish. Ouch! It sounds like torture, but actually, it wouldn’t hurt a bit – and could actually heal. New Scientist reported that a company in Israel is harvesting stinging cells from the marine creatures (like sea anemones and jellyfish) to use as microscopic hypodermic needles. These natural harpoons, called nematocysts, have more force than the pressure needed to create diamonds inside the earth. They can penetrate fish scales as well as human skin. The NanoCyte company in Israel has patented a way to control the firing of the cells by putting them in a cream. They replace the toxins in the cells with drugs that can deliver healing medicines to diabetics and others afflicted with disease. Contact with skin activates the cells and delivers the payload. Some applications are in Phase II trials. Some day, your dentist may apply gum numbing medicine to your mouth with a cream instead of a surgical needle, and you may apply anti-itch creams with technologies derived from jellyfish. The article said, “One square centimetre of cream-coated skin can contain as many as a million tiny needles.” They promise the process is painless.Now ear this: You have two sets of neurons in your inner ear, reported Science Daily. Type II neurons in the hair cells of the cochlea apparently come into play when the normal neurons are exposed to ear-piercing decibels. That being the case, they “may play a role in such reflexive withdrawals from potential trauma.”Hearing on the wing: A remarkable auditory sense has been found on butterfly wings. PhysOrg reported that a “remarkable structure” on the wing of the blue morpho butterfly acts like a tympanic membrane – an eardrum. “The unusual structure and properties of the membrane mean that this butterfly ear may be able to distinguish between low and high pitch sounds,” perhaps to detect and avoid predatory birds. “The team suggest [sic] that sensitivity to lower pitch sounds may detect the beating of birds’ wings, while higher pitches may tune into birdsong.”Lotus contemplation: The water-repellant properties of the lotus leaf (see 09/23/2009) are still being examined for secrets. PhysOrg posted a 5-second video showing a bead of water bouncing right off a lotus leaf. Duke University engineers are imitating the lotus “to improve the efficiency of modern engineering systems, such as power plants or electronic equipment, which must be cooled by removing heat through water evaporation and condensation.”Ida known better: Ida’s fame may be short-lived (see 05/19/2009). The monkey fossil that was hailed in a book and TV special as an evolutionary missing link is now being charged by another team as irrelevant and uninformative to human evolution, reported the BBC News. Of course, the discoverers of Darwinius a.k.a. Ida are not ready to concede. The new paper claims “this is an extinct side branch of the group leading to lemurs that is not in any way related to apes and monkeys.” How, then, do they explain the traits in Ida that are monkey-like? The answer, according to New Scientist: “convergent evolution”Ardi on grass? PhysOrg resurrected the theory that human evolution began when apes came down to walk in the African savannah, but did not comment on the claim this month that Ardipithecus showed our ancestors still lived in the forest trees (see 10/02/2009). New Scientist mentioned Ardi but couched the conflict in a forest of possibilities. Our ancestors in that time frame “lived either in dense forest or in a mosaic of woodland, shrub and grasses.” Now every side can win.Got genes? Scientists in the Netherlands are wondering how some people get by without 2000 chunks of DNA – about 0.12 percent of the human genome. New Scientist asked what these means in evolutionary terms. “Team leader Joris Veltman suggests that the regions his team flagged up may once have been essential but aren’t any more, either because we now need different abilities to survive, or genes have evolved elsewhere in the genome to do the same job, perhaps better.” That leaves many storytelling possibilities, but it doesn’t explain why evolution left the non-essential genes around in some people.Tinysaur and other extinct reptiles: The world’s smallest dinosaur was reported by PhysOrg – a 2-pound midget just 28 inches long. Science Daily reported a pterosaur that was named “Darwinopterus” because it is alleged to fill a gap between two groups of pterosaurs (see also National Geographic News that announced “‘Darwin’s Wing’ Fills Evolution Gap” and BBC News that called it a “missing link.”) That positivist interpretation is not without problems. Science Daily quoted a team member: “We had always expected a gap-filler with typically intermediate features such as a moderately elongate tail � neither long nor short � but the strange thing about Darwinopterus is that it has a head and neck just like that of advanced pterosaurs, while the rest of the skeleton, including a very long tail, is identical to that of primitive forms” They invoked a modification of evolutionary theory called “modular evolution” to explain this. According to this interpretation, “natural selection was acting on and changing entire modules and not, as would normally be expected, just on single features such as the shape of the snout, or the form of a tooth.” This “controversial idea” requires more study, but might be applied to “many other cases among animals and plants where we know that rapid large scale evolution must have taken place.” See Live Science for more on this idea that is newly being applied to macroevolution. Another strange-looking pterosaur seems to be supporting intelligent design rather than evolution. At least, PhysOrg reported that Sankar Chatterjee at Texas Tech admires it enough to imitate it. “At first glance, the 115-million-year-old pterosaur looks like a Cretaceous design disaster,” the article began – “With a tail rudder on its head and a spindly, bat-like body, Tapejara wellnhoferi may appear fit for nothing but extinction.” A second glance was in order, though: a team of scientists from three universities now says that “the animal’s strange body actually made it a masterpiece of nature�s drawing boards. Not only could it walk and fly, but also it could sail across the sea.” The article includes a video of Chatterjee working with models of Tapejara to invent a new spy plane. Mummy trees: “Sensational” was how one researcher described mummified trees in Norway that died in the middle ages but have not decayed for 500 years. Science Daily said it was found in a moist region where decomposition should occur quickly. Somehow the tree resin prevented decay by bacteria, insects and the wood’s own natural decomposition.Stem cell bonanza: New techniques for creating better stem cells from adult tissue were reported by Science Daily, the BBC News and PhysOrg. “The new technique, which uses three small drug-like chemicals, is 200 times more efficient and twice as fast as conventional methods for transforming adult human cells into stem cells” known as induced pluripotent stem cells (iPS). Shing Deng and a team at Scripps sought to imitate “a naturally occurring process in cells” when they hit pay dirt. The new method is “Efficient, Fast, Safe.”These are just a taste of fascinating stories coming from science labs around the world.CEH strongly supports scientific research into things that provide understanding (not just promise it) and lead to inventions that can improve our lives. The evolutionary storytelling tacked on here and there is useless and dumb. Science is making great leaps in biomimetics, biochemistry, biophysics, systems biology and genetics – fields that presuppose information and intelligent design.(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0
When it comes to charting the tree of life, the most important difference between humans and sharks isn’t limbs versus fins or even lungs versus gills. It all comes down to our skeletons. Sharks’ skeletons are made of cartilage, placing them along with rays and skates in a group of jawed vertebrates called cartilaginous fish. Humans—along with most other living vertebrates—belong to the same group as bony fish, whose skeletons are made of bone. Scientists knew that these groups diverged more than 420 million years ago, but what the last common ancestor looked like remained a mystery. Now, new discoveries inside the head of a small fossil fish from Siberia may provide some clues.The fossil material in question consists of a skull and scales of an Early Devonian fish from Siberia, approximately 415 million years old. Back in 1992, a short scientific paper noted the fossil and classified it as a bony fish belonging to the genus Dialipina, based on the scales and the head bones’ similarity to those of bony fish called Dialipina from the New Siberian Islands. Bony fish of this age are very rare, so when paleontologist Martin Brazeau at Imperial College London found a more detailed picture of the Siberian fossil fish online, he and his colleagues Sam Giles and Matt Friedman at the University of Oxford in the United Kingdom thought its origins were worth investigating in greater detail.To identify where this fish fit into the evolution of early jawed vertebrates, the team used a micro-CT scan, similar to the CT-imaging technique that patients in hospitals routinely undergo to see inside their bodies, to visualize the structure of bones inside the 1-cm-long head without destroying the fossil. Although the fossil had previously been classified as a bony fish based on its external features, such as the shape of the skull roof and the enamel on the scales, the CT scan revealed a surprising mosaic of features from both cartilaginous and bony fish. For example, the fish’s skull was made of large, bony plates similar to today’s bony fish, but the traces of the nerves and blood vessels around the brain more closely resembled those of cartilaginous fish. Reporting online today in Nature, the team named the fossil fish Janusiscus schultzei in reference to the two-faced Roman god Janus.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)The findings suggest that the common ancestor of both branches of jawed vertebrates had features of bony fish that were subsequently lost in the lineage of cartilaginous fish, like the bony plates of the skull. This backs up a 2013 study that showed that several traits thought to be unique to bony fish, such as the presence of large platelike bones, were in fact present in placoderms, an extinct group of jawed fish related to the ancestor of both cartilaginous and bony fish. It also supports a 2014 study that showed that a 325-million-year-old fossil shark had a surprising number of bony fish features, suggesting that the ancestor also had these features and that sharks may be more specialized than originally believed. These findings as a whole could correct the misconception that cartilaginous fish are more primitive than bony fish, says Giles, the lead author.Rather than one group predating the other, “both groups evolved different adaptations, and they’ve also retained different primitive features from their ancestor,” Giles explains. “Each group has found a different way of approaching the problem of living in the sea.””Janusiscus is a fascinating discovery,” says John Long, a paleontologist at Flinders University in Adelaide, Australia. It’s also one that couldn’t have been made without the use of a detailed CT scan, he notes. “Such use of modern technology is transforming the way we do paleontology by revealing new layers of information in these critical transitional fossils.”
