Kenedy put Chelsea ahead after just 39 seconds at Carrow Road and Diego Costa netted a controversial second on the stroke of half-time.Kenedy burst in from the left, dodged two challenges and fired into the far corner – his first Premier League goal.The 20-year-old Brazilian replaced the axed Baba Rahman at left-back, while Bertrand Traore was brought in by boss Guus Hiddink for his first league start for the Blues.There were also recalls for Oscar and Nemanja Matic, with Willian and John Mikel Obi dropping to the substitutes’ bench, where they are joined by Alexandre Pato, who was included in the matchday squad for the first time since his loan move.Traore might have made it 2-0 had he managed to control Eden Hazard’s pass, but his heavy touch simply nudged the ball into the arms of Norwich keeper John Ruddy, who was also able to tip over Cesc Fabregas’ free-kick.But the exciting Traore made amends by setting up Costa, who was in an offside position.The goal was allowed to stand after the Chelsea striker lifted the ball over Ruddy – his 10th goal in his last 14 matches.Chelsea, unbeaten in the league since Hiddink took over, have been well on top but were given a scare when Cameron Jerome headed over from Wes Hoolahan’s cross.And Jerome missed two glorious chances for the Canaries early in the second half.He volleyed wide from eight yards out after being found by Gary O’Neil’s cross and then contrived to volley against the top of the bar after Russell Martin had headed the ball back into the box.Chelsea: Courtois, Azpilicueta, Cahill, Ivanovic, Kenedy, Fabregas, Matic, Hazard, Oscar (Mikel 60), Traore (Willian 60), Costa.Subs: Begovic, Baba, Loftus-Cheek, Pato, Remy.Follow West London Sport on TwitterFind us on Facebook

Mammoths and mastodons roamed throughout America and Asia, evidenced by the massive fossil beds, where millions of mammoth bones can be found in permafrost. Some in the frozen tundra from Alaska to Siberia still retain soft tissue, organs and hair. These days, the two remaining species of elephants are primarily restricted to Africa and India.Art of mammoth and mastodon types found at La Brea Tar Pits, California. Photo by David Coppedge.How different are the extant types of elephants from the extinct types, such as mammoths and mastodons? With genomics, scientists can begin to answer the question. “A comprehensive genomic history of extinct and living elephants” with no less than 37 co-authors has been published in the Proceedings of the National Academy of Sciences (PNAS). The findings show a surprising amount of gene flow (i.e., sex) has taken place between the different branches on the elephant tree.Elephantids were once among the most widespread megafaunal families. However, only three species of this family exist today. To reconstruct their evolutionary history, we generated 14 genomes from living and extinct elephantids and from the American mastodon. While previous studies examined only simple bifurcating relationships, we found that gene flow between elephantid species was common in the past. Straight-tusked elephants descend from a mixture of three ancestral populations related to the ancestor of African elephants, woolly mammoths, and present-day forest elephants. We detected interbreeding between North American woolly and Columbian mammoths but found no evidence of recent gene flow between forest and savanna elephants, demonstrating that both gene flow and isolation have been central in the evolution of elephantids.This is the first comprehensive genomic assessment of the relationships between elephants, the iconic symbol of megafauna (large animals). Evolutionists have assumed a Darwinian branching tree, with species diverging and going off on their own. What the genomes show, however, is that “interspecies hybridization has been a recurrent feature of elephantid evolution.” That’s not the kind of evolution Darwin promoted. Some cases were contrary to what evolutionists used to believe:Model of Columbian mammoth displayed at Hot Springs Mammoth Site, South Dakota. Photo by David Coppedge.We found that the genetic makeup of the straight-tusked elephant, previously placed as a sister group to African forest elephants based on lower coverage data, in fact comprises three major components. Most of the straight-tusked elephant’s ancestry derives from a lineage related to the ancestor of African elephants while its remaining ancestry consists of a large contribution from a lineage related to forest elephants and another related to mammoths. Columbian and woolly mammoths also showed evidence of interbreeding, likely following a latitudinal cline across North America.What they have found is more of a network of genetic relationships rather than a branching tree. Isolation, however, can lead to genetic distance, to the point where hybridization or infertility results.While hybridization events have shaped elephantid history in profound ways, isolation also appears to have played an important role. Our data reveal nearly complete isolation between the ancestors of the African forest and savanna elephants for ∼500,000 y, providing compelling justification for the conservation of forest and savanna elephants as separate species.Hybridization is causing reassessment of what constitutes speciation. Evolution News & Science Today reported on a remarkable case of finches from New Guinea, where several indigenous species that look more different from each other than the famous Galapagos finch species are still capable of interbreeding or hybridization. A more general article on Evolution News discusses how hybridization is “weaving Darwin’s tree into a web” and making Ernst Mayr turn over in his grave. In his mission to advance Darwinism, the eminent evolutionist saw hybridization as a dead end, because he expected to see Darwin’s tree leading to reproductive isolation. Now, however, biologists are finding that some hybrids are able to produce fertile offspring. These, in turn, can “introgress” back into the ancestral species. Science Magazine says we may be on the cusp of a “third wave of a scientific revolution in biology.” New findings about hybridization, as in the case of elephantids reported above, are “shaking up the tree of life” and “challenging evolutionary theory.”Traditionally, individuals that can interbreed are considered one species. What, then, should be said of all the diverse elephant species, if gene flow occurred between them? When you think of the morphological differences between dogs, which are all one species (Canis familiaris) artificially selected for traits desirable to humans, it becomes evident that potential for variability in a single parent species can be enormous. And yet we never see a dog becoming a non-dog, or an elephant becoming a non-elephantid.A similar situation is coming to light in our own species, Homo sapiens. Where evolutionists have long split species of Homo into Neanderthals, erectus, Denisovans and a few others, new genomic studies are showing them all to be one interfertile type. Just a few days ago, for instance, it was reported that “Modern humans interbred with Denisovans twice in history” (Science Daily). Welcome to the family! As Live Science puts it, “Neanderthals Weren’t Humans’ Only Mating Partners. Meet the Denisovans.”Modern genomics is revealing networks of interfertile varieties within types that can become isolated, change, and then back-cross into their same type. It’s a very different picture from the tree metaphor of Darwin, who envisioned species branching off and going their separate ways, becoming reproductively isolated.Sign about “island dwarfism” in mammoths at Hot Springs Mammoth Site, South Dakota. Dates are disputable. Photo by David Coppedge.The picture fits the creation science called baraminology, which seeks to identify the basic types of organisms that correspond to what Genesis calls “kinds” that reproduce true to their kind. Modern creationists do not subscribe to the idea of “fixity of species” which is clearly unsupportable. Even ardent Biblical creationist Ken Ham thinks that the animals that went onto Noah’s Ark would have looked very different from living representatives of their kind. Dr Randy Guliuzza of ICR proposes that the Creator programmed variability into each type so that it could thrive as it spread into new environments. That’s programming, not “natural selection” (the “Stuff Happens” Law). Creationists also believe that substantial changes can occur rapidly. Look how quickly all the human varieties (not “races”) became accentuated since the Tower of Babel, and yet all humans remain interfertile. In extreme cases, we know that Europeans easily married native Americans in both North and South America, and had healthy children, even though they came from families that had migrated in opposite directions around the globe thousands of years ago. As creationists have loosened up on their ideas of allowable variability within kinds, evolutionists are facing contradictions to their long-held views about speciation. Genomic evidence is tangling up their beloved tree of life, weaving it into a bush with interconnected branches. Genetic evidence (including epigenetic processes the early evolutionists knew nothing about) appears consistent with rapid variation within created kinds, with programmed variability that allows for adjusting to new environments. That’s design, not evolution as Darwin viewed it. There’s no upward progress from bacteria to man (or elephant), just variations on themes set during the Creation week of Genesis.

(AP Photo/Gerry Broome)CHARLOTTE, N.C. — Buzz Peterson knew Michael Jordan as well as anyone when they were in college.Roommates and teammates at North Carolina, they spent countless days competing on the basketball court in practice and endless hours talking hoops. Their nights often included shooting pool and tossing cards in their Granville Towers South dorm room. There often were arcade games — before the home video game craze hit — at the Pump House on Franklin Street in downtown Chapel Hill.ADVERTISEMENT Forbes Magazine estimated Jordan’s net worth in 2018 at $1.6 billion.“Remarkable,” Peterson said, “you almost have to pinch yourself.”Dell Curry says Jordan wants nothing but the best in anything he does — including this weekend’s All-Star game.“He’s excited for the NBA to come to his home state and play in the building of the team he owns,” said Curry, the Hornets color commentator and former NBA player. “So he is going to roll out the red carpet. He only knows one way to do it, and that is big time.”Added James Jordan: “I think when it’s all over, he will sit back and relax and maybe smoke a cigar and say ‘that was a great event,’ and just be really proud of himself that he made it happen.”Sports Related Videospowered by AdSparcRead Next Grace Poe files bill to protect govt teachers from malicious accusations MOST READ “Michael has always been very sharp, very smart,” said Peterson, who now works as an assistant general manager for Jordan’s Charlotte Hornets. “He’s a very good listener. He gathers information and opinions and then makes decisions. And once he makes the decision to go after something, he goes all out. He is absolutely driven to be successful in whatever he chooses.”It’s well-known that Jordan uses failure to motivate him.The only thing seemingly that has eluded Jordan, who turns 56 on Sunday — the day of the All-Star game — is ultimate success as an executive and team owner.His Hornets have yet to win a playoff series since he took over as majority owner nine years ago and they remain mired in NBA mediocrity while struggling to compete in a small market.But Jordan wants to keep his team — and the city — relevant. It’s one reason he aggressively pursued the All-Star game with such vigor.ADVERTISEMENT Don’t miss out on the latest news and information. But Peterson never saw this coming: His roommate becoming an NBA owner and hosting the league’s All-Star game in his home state of North Carolina.“You know, staring across the dorm room at him back then, no, I never would have thought this would happen,” Peterson told The Associated Press.FEATURED STORIESSPORTSPrivate companies step in to help SEA Games hostingSPORTSUrgent reply from Philippine football chiefSPORTSPalace wants Cayetano’s PHISGOC Foundation probed over corruption chargesThat’s understandable; they were young kids who didn’t know any better.Looking back now, Peterson said he should have known what Jordan’s parents instilled in him: He could achieve anything and he was destined for something extraordinary. “I think getting the All-Star game here is an accomplishment that will go on his list, and it will stand out for him because it’s really not about him,” said James Jordan Jr., Michael’s older brother. “This is an event that’s bigger than him. It’s really about the world — and he’s going to be the host of it.”On the court, after not being able to make his school varsity as a sophomore, he went on to become a two-time All-American, NCAA champion and the national college player of the year in 1984. He is a two-time Olympic gold medalist and won three straight NBA titles — and after a stint in minor league baseball — returned to the league and won three more.Off the court, Jordan marketed his on-court success into a fortune.“He has always had incredible determination — always,” said Fred Lynch, Jordan’s former junior varsity basketball coach at Wilmington’s Laney High School.James Jordan Jr. said it comes from their parents.He describes Michael as a “country boy” who never lost sight of his work ethic. He was the youngest of the three boys who relished a challenge, and James Jr. said their parents, James Sr. and Deloris Jordan, always taught the boys to go after their dreams.“Our parents taught us that you can achieve anything you want, but you have to have drive, that motivation — and you have to work hard at it,” said James Jordan Jr., who now works as an executive for the Hornets after spending 31 years in the military.Jordan changed the shoe game when Nike created Air Jordan, which he later spun off into the Jordan Brand.Now, when fans see the Jumpman logo, they think of Jordan.“I think it was easy to envision Michael doing anything at that point,” said former Chicago Bulls teammate Steve Kerr. “He was conquering the NBA world as a player and as a shoe salesman and endorser, so I think we all just felt like the sky was the limit. So this (hosting an All-Star game) is not that surprising to me at all.” PH underwater hockey team aims to make waves in SEA Games PLAY LIST 02:42PH underwater hockey team aims to make waves in SEA Games01:44Philippines marks anniversary of massacre with calls for justice01:19Fire erupts in Barangay Tatalon in Quezon City01:07Trump talks impeachment while meeting NCAA athletes02:49World-class track facilities installed at NCC for SEA Games02:11Trump awards medals to Jon Voight, Alison Krauss ‘We are too hospitable,’ says Sotto amid SEA Games woes Oil plant explodes in Pampanga town Oil plant explodes in Pampanga town ‘We are too hospitable,’ says Sotto amid SEA Games woes US judge bars Trump’s health insurance rule for immigrants SEA Games hosting troubles anger Duterte Private companies step in to help SEA Games hosting LATEST STORIES Regine Arocha delivers another performance worthy of NCAA volleyball Finals MVP View comments
