Question: Andrew Gary Johns (born 19 May 1974) is an Australian former professional rugby league footballer of the 1990s and 2000s. He is considered by many to be one of the greatest players of all time. Hailed as the best halfback in the world for many years, he captained the Newcastle Knights in the National Rugby League and participated in the team's only two premiership victories in 1997 and 2001, playing a club record 249 games for the Knights. Johns also represented his country at two World Cups, and on one Kangaroo tour, playing in total 21 Test matches for the national side.

On 26 August 2007 Johns was arrested for fare evasion on the London Underground, and subsequently found to be in possession of one ecstasy tablet. He was cautioned and released with no further charges. Johns initially claimed that an unknown person had pushed the tablet into his pocket which he later forgot to remove before leaving the crowded venue. This initial statement was met with a great deal of cynicism from both the press and the public. On 30 August, Johns revealed, live on the Footy Show, that he had regularly taken ecstasy throughout his playing career, mainly during the off-season. He claimed he had suffered from depression and bipolar disorder and the drugs helped him in dealing with the high level of psychological 'pressure' associated with his career as an elite sportsman. Not long after the incident he released his 'tell-all' autobiography that went into further details regarding his depression and drug use while playing in the NRL.  The ARU released a press statement shortly after the controversy arose, stating that Johns' drug use was known to the ARU and was a key factor in its decision to not proceed with contractual negotiations in 2004. Brett Robinson, then high-performance unit manager, said that, as well as Johns' age and injury history, the knowledge of his drug taking had been influential in the ARU making its final decision.  When Johns was named the Best Player of the Last 30 Years in early 2008, the accolade allayed concern that Johns' shock drug admission the year before had tarnished his remarkable efforts on the field for Newcastle, NSW and Australia. On receiving the award he was quoted as saying his health was now in great shape. "I'm at the best place I have been in a long time," he said. "It's not until you step away that I realise all the pressure I was under, I'm not going to miss playing at all."

Using a quote from the above article, answer the following question: Did he ever go on TV and state why he took drugs?

Answer: On 30 August, Johns revealed, live on the Footy Show, that he had regularly taken ecstasy throughout his playing career,


Question: Richard Charles "Dick" Lewontin (born March 29, 1929) is an American evolutionary biologist, mathematician, geneticist, and social commentator. A leader in developing the mathematical basis of population genetics and evolutionary theory, he pioneered the application of techniques from molecular biology, such as gel electrophoresis, to questions of genetic variation and evolution. In a pair of seminal 1966 papers co-authored with J.L. Hubby in the journal Genetics, Lewontin helped set the stage for the modern field of molecular evolution. In 1979 he and Stephen Jay Gould introduced the term "spandrel" into evolutionary theory.

Lewontin has worked in both theoretical and experimental population genetics. A hallmark of his work has been an interest in new technology. He was the first person to do a computer simulation of the behavior of a single gene locus (previous simulation work having been of models with multiple loci). In 1960 he and Ken-Ichi Kojima were the first population geneticists to give the equations for change of haplotype frequencies with interacting natural selection at two loci. This set off a wave of theoretical work on two-locus selection in the 1960s and 1970s. Their paper gave a theoretical derivation of the equilibria expected, and also investigated the dynamics of the model by computer iteration. Lewontin later introduced the D' measure of linkage disequilibrium. (He also introduced the term "linkage disequilibrium", about which many population geneticists have been unenthusiastic.)  In 1966, he and Jack Hubby published a paper that revolutionized population genetics. They used protein gel electrophoresis to survey dozens of loci in the fruit fly Drosophila pseudoobscura, and reported that a large fraction of the loci were polymorphic, and that at the average locus there was about a 15% chance that the individual was heterozygous. (Harry Harris reported similar results for humans at about the same time.) Previous work with gel electrophoresis had been reports of variation in single loci and did not give any sense of how common variation was.  Lewontin and Hubby's paper also discussed the possible explanation of the high levels of variability by either balancing selection or neutral mutation. Although they did not commit themselves to advocating neutrality, this was the first clear statement of the neutral theory for levels of variability within species. Lewontin and Hubby's paper had great impact--the discovery of high levels of molecular variability gave population geneticists ample material to work on, and gave them access to variation at single loci. The possible theoretical explanations of this rampant polymorphism became the focus of most population genetics work thereafter. Martin Kreitman was later to do a pioneering survey of population-level variability in DNA sequences while a Ph.D. student in Lewontin's lab.
