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 ... [...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. They are not purposeful, but instead are evolutionary and are spontaneously produced by female primates, including women, to encourage her partner to produce good-quality sperm during the mating process. Copulatory vocalizations usually occur during copulation (zoology), 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 primate Primates is an order (biology), order of mammals, which is further divided into the Strepsirrhini, strepsirrhines, which include lemurs, galagos, and Lorisidae, lorisids; and the Haplorhini, haplorhines, which include Tarsiiformes, tarsiers a ...s, copulation calling is typically observed at the end of mating and there are vast variations between species regarding i ...

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 ... [...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.

Neolithic Revolution
The Neolithic Revolution, also known as the First Agricultural Revolution, was the wide-scale transition of many human cultures during the Neolithic period in Afro-Eurasia from a lifestyle of hunter-gatherer, hunting and gathering to one of agriculture and sedentism, 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 indicate that the domestication of various types of plants and animals happened in separate locations worldwide, starting in the Geologic time scale, geological epoch of the Holocene 11,700 years ago, after the end of the last Ice Age. It was humankind's first historically verifiable transition to agriculture. The Neolithic Revolution greatly narrowed the diversity of foods available, resulting in a decrease in the quality of human nutrition compared ...

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. History The term "conventional wisdom" dates back to at least 1838, as a synonym for "commonplace knowledge". It was used in a number of works, 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 Technique of Thomas Hardy'' (1922), page 152("He has not the colorless monotony of the business man who follows sure ways to success, who has conformed to every rule of conventional wisdom, and made himself as featureless as a potato field, as tame as ...

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 t ...

Sexual Selection
Sexual selection is a mechanism of evolution in which members of one 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 Fisher in the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sperm Competition
Sperm competition is the competitive process between Spermatozoon, spermatozoa of two or more different males to fertility, fertilize the same Egg cell, 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 male's chance of reproductive success. Sperm competition results in a sexual conflict 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 succes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
