IN: Zheng He (Chinese: Zheng He ; 1371-1433 or 1435) was a Chinese mariner, explorer, diplomat, fleet admiral, and court eunuch during China's early Ming dynasty. He was originally born as Ma He in a Muslim family, later adopted the conferred surname Zheng from Emperor Yongle. Zheng commanded expeditionary voyages to Southeast Asia, South Asia, Western Asia, and East Africa from 1405 to 1433. His larger ships stretched 120 meters or more in length.

Ma He was captured by the Ming armies at Yunnan in 1381. General Fu Youde saw Ma He on a road and approached him in order to inquire about the location of the Mongol pretender. Ma He responded defiantly by saying that the Mongol pretender had jumped into a lake. Afterwards, the general took him prisoner. He was castrated before being placed in servitude of the Prince of Yan at age 10, although another source indicates the castration occurred in 1385.  Ma was sent to serve in the household of Zhu Di, the Prince of Yan, who later became the Yongle Emperor. Zhu Di was eleven years older than Ma. Since 1380, the prince had been governing Beiping (later Beijing), which was located near the northern frontier where the hostile Mongol tribes were situated. Ma would spend his early life as a soldier on the northern frontier. He often participated in Zhu Di's military campaigns against the Mongols. On 2 March 1390, Ma accompanied the Prince when he commanded his first expedition, which was a great victory as the Mongol commander Naghachu surrendered as soon as he realized he had fallen for a deception.  Eventually, he would gain the confidence and trust of the prince. Ma was also known as "san bao" during the time of service in the household of the Prince of Yan. This name was a reference to the Three Jewels (San Bao , triratna) in Buddhism. There is also document saying his name could be San Bao  (lit. "Three Protections", also pronounced san bao). Ma received a proper education while at Beiping, which he would not have had if he had been placed in the imperial capital Nanjing, as the Hongwu Emperor did not trust eunuchs and believed that it was better to keep them illiterate. Meanwhile, the Hongwu Emperor purged and exterminated many of the original Ming leadership and gave his enfeoffed sons more military authority, especially those in the north like the Prince of Yan.

IN: 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.
