Problem: 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.

Along with others, such as Gould, Lewontin has been a persistent critic of some themes in neo-Darwinism. Specifically, he has criticised proponents of sociobiology and evolutionary psychology such as Edward O. Wilson and Richard Dawkins, who attempt to explain animal behaviour and social structures in terms of evolutionary advantage or strategy. He and others criticize this approach when applied to humans, as he sees it as genetic determinism. In his writing, Lewontin suggests a more nuanced view of evolution is needed, which requires a more careful understanding of the context of the whole organism as well as the environment. Such concerns about what he views as the oversimplification of genetics has led Lewontin to be a frequent participant in debates, and an active life as a public intellectual. He has lectured widely to promote his views on evolutionary biology and science. In books such as Not in Our Genes (co-authored with Steven Rose and Leon J. Kamin) and numerous articles, Lewontin has questioned much of the claimed heritability of human behavioral traits, such as intelligence as measured by IQ tests. Some academics have criticized him for rejecting sociobiology for non-scientific reasons. Edward Wilson (1995) suggested that Lewontin's political beliefs affected his scientific view. Robert Trivers described Lewontin as "...a man with great talents who often wasted them on foolishness, on preening and showing off, on shallow political thinking and on useless philosophical rumination while limiting his genetic work by assumptions congenial to his politics." Lewontin has at times identified himself as Marxist, and admitted that his ideological views have affected his scientific work (Levins and Lewontin 1985). Others such as Kitcher (1985) have countered that Lewontin's criticisms of sociobiology are genuine scientific concerns about the discipline. He wrote that attacking Lewontin's motives amounts to an ad hominem argument.

Problem: Browning was born as Charles Albert Browning, Jr., in Louisville, Kentucky, the second son of Charles Albert and Lydia Browning, and the nephew of baseball star Pete Browning. As a young boy, he put on amateur plays in his backyard. He was fascinated by the circus and carnival life, and at the age of 16 he ran away from his well-to-do family to become a performer. Changing his name to "Tod", he traveled extensively with sideshows, carnivals, and circuses.

After Chaney's death in 1930, Browning was hired by his old employer Universal Pictures to direct Dracula (1931). Although Browning wanted to hire an unknown European actor for the title role and have him be mostly offscreen as a sinister presence, budget constraints and studio interference necessitated the casting of Bela Lugosi and a more straightforward approach. After directing the boxing melodrama Iron Man (1931), Browning began work on Freaks (1932). Based on the short story "Spurs" by Clarence Aaron "Tod" Robbins, the screenwriter of The Unholy Three, the film concerns a love triangle between a wealthy dwarf, a gold-digging aerialist, and a strongman; a murder plot; and the vengeance dealt out by the dwarf and his fellow circus freaks. The film was highly controversial, even after heavy editing to remove many disturbing scenes, and was a commercial failure and banned in the United Kingdom for thirty years. His career derailed, Browning found himself unable to get his requested projects greenlighted. After directing the drama Fast Workers (1933) starring John Gilbert, who was also not in good standing with the studio, he was allowed to direct a remake of London After Midnight, originally titled Vampires of Prague but later retitled Mark of the Vampire (1935). In the remake, the roles played by Lon Chaney in the original were split between Lionel Barrymore and Bela Lugosi (spoofing his Dracula image). After that, Browning directed The Devil-Doll (1936), originally titled The Witch of Timbuctoo, from his own script. The picture starred Lionel Barrymore as an escapee from an island prison who avenges himself on the people who imprisoned him using living "dolls" who are actually people shrunk to doll-size and magically placed under Barrymore's hypnotic control. Browning's final film was the murder mystery Miracles for Sale (1939).
