Answer the question at the end by quoting:

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.

What explanation did the paper talk about?

Their paper gave a theoretical derivation of the equilibria expected, and also investigated the dynamics of the model by computer iteration.

IN: Allen Toussaint (; January 14, 1938 - November 10, 2015) was an American musician, songwriter, arranger and record producer, who was an influential figure in New Orleans R&B from the 1950s to the end of the century, described as "one of popular music's great backroom figures." Many musicians recorded Toussaint's compositions, including "Java", "Mother-in-Law", "I Like It

In 1960, Joe Banashak, of Minit Records and later Instant Records, hired Toussaint as an A&R man and record producer. He also did freelance work for other labels, such as Fury. Toussaint played piano, wrote, arranged and produced a string of hits in the early and mid-1960s for New Orleans R&B artists such as Ernie K-Doe, Chris Kenner, Irma Thomas (including "It's Raining"), Art and Aaron Neville, the Showmen, and Lee Dorsey, whose first hit "Ya Ya" he produced in 1961. The early to mid-1960s are regarded as Toussaint's most creatively successful period. Notable examples of his work are Jessie Hill's "Ooh Poo Pah Doo" (written by Hill and arranged and produced by Toussaint), Ernie K-Doe's "Mother-in-Law", and Chris Kenner's "I Like It Like That". A two-sided 1962 hit by Benny Spellman comprised "Lipstick Traces (on a Cigarette)" (covered by the O'Jays, Ringo Starr, and Alex Chilton) and the simple but effective "Fortune Teller" (covered by various 1960s rock groups, including the Rolling Stones, the Nashville Teens, the Who, the Hollies, the Throb, and ex-Searchers founder Tony Jackson). "Ruler of My Heart", written under his pseudonym Naomi Neville, first recorded by Irma Thomas for the Minit label in 1963, was adapted by Otis Redding under the title "Pain in My Heart" later that year, prompting Toussaint to file a lawsuit against Redding and his record company, Stax (the claim was settled out of court, with Stax agreeing to credit Naomi Neville as the songwriter). Redding's version of the song was also recorded by the Rolling Stones on their second album. In 1964, "A Certain Girl" (originally by Ernie K-Doe) was the B-side of the first single release by the Yardbirds. The song was released again in 1980 by Warren Zevon, as the single from the album Bad Luck Streak in Dancing School it reached 57 on Billboard's Hot 100. Mary Weiss, former lead singer of The Shangri-Las, released it as "A Certain Guy" in 2007. Toussaint credited about twenty songs to his parents, Clarence and Naomi, sometimes using the pseudonym "Naomi Neville". These include "Fortune Teller", first recorded by Benny Spellman in 1961, and "Work, Work, Work", recorded by the Artwoods in 1966. Alison Krauss and Robert Plant covered "Fortune Teller" on their 2007 album Raising Sand.
