Sex At Dawn
''Sex at Dawn: The Prehistoric Origins of Modern Sexuality'' is a 2010 book about the evolution of human mating systems by Christopher Ryan and Cacilda Jethá. In opposition to what the authors see as the "standard narrative" of human sexual evolution, they contend that having multiple sexual partners was common and accepted in the environment of evolutionary adaptedness. The authors contend that mobile, self-contained groups of hunter-gatherers were the norm for humans before agriculture led to high population density. Before agriculture, according to the authors, sex was relatively promiscuous and paternity was not a concern. This dynamic is similar to the mating system of bonobos. According to the book, sexual interactions strengthened the bond of trust in the groups. Far from causing jealousy, social equilibrium and reciprocal obligation were strengthened by playful sexual interactions. The book generated a great deal of publicity in the popular press where it was met with g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Female Copulatory Vocalization
Female copulatory vocalizations, also called female copulation calls or coital vocalizations, are produced by female primates, including human females, and female non-primates. Copulatory vocalizations usually occur during copulation and are hence related to sexual activity. Vocalizations that occur before intercourse, for the purpose of attracting mates, are known as mating calls. In primates, copulation calling is typically observed at the end of mating and there are vast variations between species regarding its occurrence, frequency and form. It is agreed that coital vocalizations fulfill an evolutionary purpose and that they serve as adaptive solutions to problems that the females face, such as infanticide, as well as obtaining high quality sperm. In non-primates, copulatory calling predominantly occurs before copulation in order to attract mates (mating call). Calls vary in frequency (14 Hz to 70,000 Hz) and function. One of the main purposes of females vocalizing is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred Kinsey
Alfred Charles Kinsey (; June 23, 1894 – August 25, 1956) was an American sexologist, biologist, and professor of entomology and zoology who, in 1947, founded the Institute for Sex Research at Indiana University, now known as the Kinsey Institute for Research in Sex, Gender, and Reproduction. He is best known for writing ''Sexual Behavior in the Human Male'' (1948) and ''Sexual Behavior in the Human Female'' (1953), also known as the Kinsey Reports, as well as for the Kinsey scale. Kinsey's research on human sexuality, foundational to the field of sexology, provoked controversy in the 1940s and 1950s, and, because of accepting data donation from pedophiles in particular has continued to provoke controversy decades after his death. His work has influenced social and cultural values in the United States as well as internationally. Early life and education Alfred Kinsey was born on June 23, 1894, in Hoboken, New Jersey, the son of Sarah Ann ( Charles) and Alfred Seguine Kinsey. ...

Sex Columnist
A sex columnist is a writer of a newspaper or magazine column about sex. Sex advice columns may take the form of essays or, more frequently, answers to questions posed by readers. Sex advice columns can usually be found in alt weekly newspapers, women's magazines, health or fitness magazines, and student newspapers. While some are written by sexologists, many are penned by people lacking credentials in human sexuality and relationships, yet willing to divulge their opinions or personal bedroom antics. The television series ''Sex and the City'' protagonist Carrie Bradshaw was a sex columnist, which author Candace Bushnell modeled after herself in her original non-fiction book based on a column of the same name. The show, which first aired in 1998, is credited with the increase of sex columnists found in college campus newspapers and blogs, such as at Ivy League colleges and many other schools. One such columnist, Meghan Bainum, at the University of Kansas, Lawrence, placed in the 4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New York Times Best Seller List
''The New York Times'' Best Seller list is widely considered the preeminent list of best-selling books in the United States. John Bear, ''The #1 New York Times Best Seller: intriguing facts about the 484 books that have been #1 New York Times bestsellers since the first list, 50 years ago'', Berkeley: Ten Speed Press, 1992. Since October 12, 1931, ''The New York Times Book Review'' has published the list weekly. In the 21st century, it has evolved into multiple lists, grouped by genre and format, including fiction and non-fiction, hardcover, paperback and electronic. The list is based on a proprietary method that uses sales figures, other data and internal guidelines that are unpublished—how the ''Times'' compiles the list is a trade secret. In 1983 (as part of a legal argument), the ''Times'' stated that the list is not mathematically objective but rather editorial content. In 2017, a ''Times'' representative said that the goal is that the lists reflect authentic best selle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Neolithic Revolution
The Neolithic Revolution, or the (First) Agricultural Revolution, was the wide-scale transition of many human cultures during the Neolithic period from a lifestyle of hunting and gathering to one of agriculture and settlement, making an increasingly large population possible. These settled communities permitted humans to observe and experiment with plants, learning how they grew and developed. This new knowledge led to the domestication of plants into crops. Archaeological data indicates that the domestication of various types of plants and animals happened in separate locations worldwide, starting in the geological epoch of the Holocene 11,700 years ago. It was the world's first historically verifiable revolution in agriculture. The Neolithic Revolution greatly narrowed the diversity of foods available, resulting in a downturn in the quality of human nutrition compared with that obtained previously from foraging. The Neolithic Revolution involved far more than the adoption ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conventional Wisdom
The conventional wisdom or received opinion is the body of ideas or explanations generally accepted by the public and/or by experts in a field. In religion, this is known as orthodoxy. Etymology The term is often credited to the economist John Kenneth Galbraith, who used it in his 1958 book ''The Affluent Society'':''E.g.,'Mark Leibovich, "A Scorecard on Conventional Wisdom", ''N.Y. Times'' (March 9, 2008) However, the term dates back to at least 1838. ''Conventional wisdom'' was used in a number of other works before Galbraith, occasionally in a benign''E.g.,'1 Nahum Capen, ''The History of Democracy'' (1874), page 477("millions of all classes alike are equally interested and protected by the practical judgment and conventional wisdom of ages"). or neutral''E.g.,'"Shallow Theorists", ''American Educational Monthly'' 383 (Oct. 1866)("What is the result? Just what conventional wisdom assumes it would be."). sense, but more often pejoratively.''E.g.,'Joseph Warren Beach, ''The Te ...

Partible Paternity
Partible paternity or shared paternity is a cultural conceptualization of paternity according to which a child is understood to have more than one father; for example, because of an ideology that sees pregnancy as the cumulative result of multiple acts of sexual intercourse. In societies with the concept of partible paternity this often results in the nurture of a child being shared by multiple fathers in a form of polyandric relation to the mother, although this is not always the case. All cultures recognize different types of fatherhood – for example the distinction between biological fatherhood and legal fatherhood, and the corresponding social roles of ''genitor'' and ''pater''. The concept of partible paternity differs from such a distinction because it considers all men who have had sexual intercourse with a woman immediately prior to and during her pregnancy to have contributed biological material to the child, and to have a corresponding legal or moral responsibility to ...

Sexual Selection
Sexual selection is a mode of natural selection in which members of one biological sex mate choice, choose mates of the other sex to mating, mate with (intersexual selection), and compete with members of the same sex for access to members of the opposite sex (intrasexual selection). These two forms of selection mean that some individuals have greater reproductive success than others within a population, for example because they are more Animal sexual behaviour, attractive or prefer more attractive partners to produce offspring. Successful males benefit from frequent mating and monopolizing access to one or more fertile females. Females can maximise the return on the energy they invest in reproduction by selecting and mating with the best males. The concept was first articulated by Charles Darwin who wrote of a "second agency" other than natural selection, in which competition between mate candidates could lead to speciation. The theory was given a mathematical basis by Ronald F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sperm Competition
Sperm competition is the competitive process between spermatozoa of two or more different males to fertilize the same egg during sexual reproduction. Competition can occur when females have multiple potential mating partners. Greater choice and variety of mates increases a female's chance to produce more viable offspring. However, multiple mates for a female means each individual male has decreased chances of producing offspring. Sperm competition is an evolutionary pressure on males, and has led to the development of adaptations to increase males' chance of reproductive success. Sperm competition results in a sexual conflict of interest between males and females. Males have evolved several defensive tactics including: mate-guarding, mating plugs, and releasing toxic seminal substances to reduce female re-mating tendencies to cope with sperm competition. Offensive tactics of sperm competition involve direct interference by one male on the reproductive success of another male, for ...
