Question: The Corrs are an Irish band that combine pop rock with traditional Irish themes within their music. The group consists of the Corr siblings; Andrea (lead vocals, tin whistle, ukulele); Sharon (violin, vocals); Caroline (drums, percussion, piano, bodhran, vocals) and Jim (guitar, piano, keyboards, vocals). They are from Dundalk, County Louth, Ireland. The Corrs have released seven studio albums and numerous singles, which have reached Platinum in many countries, and have sold 40 million albums worldwide.

Jason Flom, Atlantic Records's head of A&R, recommended that they meet David Foster, a Canadian musician, producer, composer and arranger. The Corrs played live for Foster and he agreed to sign them to Atlantic Records. They extended their stay in the US for over five months to record their debut album, Forgiven, Not Forgotten. It featured six instrumental selections among its Celtic-influenced tracks. The album sold well in Ireland, Australia, Japan, Norway and Spain. Major success in the US and the UK, however, was not immediately forthcoming. Eventually, the album reached Platinum status in the UK and Australia, and 4x Platinum in Ireland, making it one of the most successful debuts by an Irish group.  The Corrs' next album, 1997's Talk on Corners, was produced by Glen Ballard, who was respected for his collaboration with Alanis Morissette. The Corrs also collaborated with Carole Bayer Sager, Oliver Leiber, Rick Nowels and Billy Steinberg. The album met with lukewarm response. It was successful in Ireland and entered the Australian album charts at number 3.  After the band recorded a version of Dreams for a Fleetwood Mac tribute album, they re-released Talk on Corners, with new remixes of "What Can I Do?", "So Young" and "Runaway". The special edition topped the charts worldwide and again reached multi-Platinum status in the UK and Australia.  In June 1998, The Corrs participated in the Pavarotti and Friends for the Children of Liberia charity concert. The concert was held in Modena, Italy and was hosted by Luciano Pavarotti. Other performers included Jon Bon Jovi, Celine Dion, Spice Girls and Stevie Wonder. The concert aimed to raise money to build the Pavarotti and Friends Liberian Children's Village, to provide refuge for children in Liberia.  The following year, The Corrs received a BRIT Award for Best International Band. They performed live on MTV's Unplugged on 5 October 1999 at Ardmore Studios, Co. Wicklow, Ireland. The resulting CD and DVD sold 2.7 million copies and featured live performances of previously released songs, plus a new song, "Radio", later featured on their third album, In Blue.

Using a quote from the above article, answer the following question: Who did they work with for the album?
HHHHHH
Answer: Glen Ballard, who was respected for his collaboration with Alanis Morissette.


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.
