Pinker and Bloom argue that language as a mental faculty shares many likenesses with the complex organs of the body which suggests that, like these organs, language has evolved as an adaptation, since this is the only known mechanism by which such complex organs can develop. Pinker follows Chomsky in arguing that the fact that children can learn any human language with no explicit instruction suggests that language, including most of grammar, is basically innate and that it only needs to be activated by interaction.

Chomsky himself does not believe language to have evolved as an adaptation, but suggests that it likely evolved as a byproduct of some other adaptation, a so-called spandrel. But Pinker and Bloom argue that the organic nature of language strongly suggests that it has an adaptational origin.

Evolutionary psychologists hold that the FOXP2 gene may well be associated with the evolution of human language. Currently several competing theories about the evolutionary origin of language coexist, none of them having achieved a general consensus.

Tomasello argues that studies of how children and primates actually acquire communicative skills suggests that humans learn complex behavior through experience, so that instead of a module specifically dedicated to language acquisition, language is acquired by the same cognitive mechanisms that are used to acquire all other kinds of socially transmitted behavior. On the issue of whether language is best seen as having evolved as an adaptation or as a spandrel, evolutionary biologist W.

Tecumseh Fitch, following Stephen J. Gould, argues that it is unwarranted to assume that every aspect of language is an adaptation, or that language as a whole is an adaptation. He criticizes some strands of evolutionary psychology for suggesting a pan-adaptionist view of evolution, and dismisses Pinker and Bloom's question of whether 'Language has evolved as an adaptation' as being misleading.

He argues instead that from a biological viewpoint the evolutionary origins of language is best conceptualized as being the probable result of a convergence of many separate adaptations into a complex system. If the theory that language could have evolved as a single adaptation is accepted, the question becomes which of its many functions has been the basis of adaptation. Several evolutionary hypotheses have been posited: that language evolved for the purpose of social grooming, that it evolved as a way to show mating potential or that it evolved to form social contracts.

Evolutionary psychologists recognize that these theories are all speculative and that much more evidence is required to understand how language might have been selectively adapted. Given that sexual reproduction is the means by which genes are propagated into future generations, sexual selection plays a large role in human evolution. Human mating, then, is of interest to evolutionary psychologists who aim to investigate evolved mechanisms to attract and secure mates.

In Robert Trivers published an influential paper [94] on sex differences that is now referred to as parental investment theory. The size differences of gametes anisogamy is the fundamental, defining difference between males small gametes — sperm and females large gametes — ova. Trivers noted that anisogamy typically results in different levels of parental investment between the sexes, with females initially investing more.

Trivers proposed that this difference in parental investment leads to the sexual selection of different reproductive strategies between the sexes and to sexual conflict. For example, he suggested that the sex that invests less in offspring will generally compete for access to the higher-investing sex to increase their inclusive fitness also see Bateman's principle [95]. Trivers posited that differential parental investment led to the evolution of sexual dimorphisms in mate choice, intra- and inter- sexual reproductive competition, and courtship displays.

In mammals, including humans, females make a much larger parental investment than males i. Parental investment theory is a branch of life history theory. Buss and Schmitt's Sexual Strategies Theory [96] proposed that, due to differential parental investment, humans have evolved sexually dimorphic adaptations related to 'sexual accessibility, fertility assessment, commitment seeking and avoidance, immediate and enduring resource procurement, paternity certainty, assessment of mate value, and parental investment.

Women are generally more selective when choosing mates, especially under long term mating conditions. However, under some circumstances, short term mating can provide benefits to women as well, such as fertility insurance, trading up to better genes, reducing risk of inbreeding, and insurance protection of her offspring.

Due to male paternity insecurity, sex differences have been found in the domains of sexual jealousy. This particular pattern is predicted because the costs involved in mating for each sex are distinct. Women, on average, should prefer a mate who can offer resources e. Men, on the other hand, are never certain of the genetic paternity of their children because they do not bear the offspring themselves 'paternity insecurity'.

This suggests that for men sexual infidelity would generally be more aversive than emotional infidelity because investing resources in another man's offspring does not lead to propagation of their own genes. Another interesting line of research is that which examines women's mate preferences across the ovulatory cycle.

Known as the ovulatory shift hypothesis, the theory posits that, during the ovulatory phase of a woman's cycle approximately days 10—15 of a woman's cycle , [] a woman who mated with a male with high genetic quality would have been more likely, on average, to produce and rear a healthy offspring than a woman who mated with a male with low genetic quality.

These putative preferences are predicted to be especially apparent for short-term mating domains because a potential male mate would only be offering genes to a potential offspring. This hypothesis allows researchers to examine whether women select mates who have characteristics that indicate high genetic quality during the high fertility phase of their ovulatory cycles.

Indeed, studies have shown that women's preferences vary across the ovulatory cycle. In particular, Haselton and Miller showed that highly fertile women prefer creative but poor men as short-term mates. Creativity may be a proxy for good genes. Reproduction is always costly for women, and can also be for men. Individuals are limited in the degree to which they can devote time and resources to producing and raising their young, and such expenditure may also be detrimental to their future condition, survival and further reproductive output.

Parental investment is any parental expenditure time, energy etc. Components of fitness Beatty include the well-being of existing offspring, parents' future reproduction, and inclusive fitness through aid to kin Hamilton, Robert Trivers' theory of parental investment predicts that the sex making the largest investment in lactation, nurturing and protecting offspring will be more discriminating in mating and that the sex that invests less in offspring will compete for access to the higher investing sex see Bateman's principle.

The benefits of parental investment to the offspring are large and are associated with the effects on condition, growth, survival and ultimately, on reproductive success of the offspring. However, these benefits can come at the cost of parent's ability to reproduce in the future e.

Overall, parents are selected to maximize the difference between the benefits and the costs, and parental care will likely evolve when the benefits exceed the costs. The Cinderella effect is an alleged high incidence of stepchildren being physically, emotionally or sexually abused, neglected, murdered, or otherwise mistreated at the hands of their stepparents at significantly higher rates than their genetic counterparts.

It takes its name from the fairy tale character Cinderella, who in the story was cruelly mistreated by her stepmother and stepsisters. Parental efforts and investments are valuable resources, and selection favors those parental psyches that allocate effort effectively to promote fitness.

The adaptive problems that challenge parental decision making include both the accurate identification of one's offspring and the allocation of one's resources among them with sensitivity to their needs and abilities to convert parental investment into fitness increments….

However, they note that not all stepparents will 'want' to abuse their partner's children, or that genetic parenthood is any insurance against abuse. They see step parental care as primarily 'mating effort' towards the genetic parent. Inclusive fitness is the sum of an organism's classical fitness how many of its own offspring it produces and supports and the number of equivalents of its own offspring it can add to the population by supporting others.

From the gene's point of view, evolutionary success ultimately depends on leaving behind the maximum number of copies of itself in the population. Until , it was generally believed that genes only achieved this by causing the individual to leave the maximum number of viable offspring. However, in W. Hamilton proved mathematically that, because close relatives of an organism share some identical genes, a gene can also increase its evolutionary success by promoting the reproduction and survival of these related or otherwise similar individuals.

Hamilton concluded that this leads natural selection to favor organisms that would behave in ways that maximize their inclusive fitness. It is also true that natural selection favors behavior that maximizes personal fitness. Hamilton's rule describes mathematically whether or not a gene for altruistic behavior will spread in a population:. The concept serves to explain how natural selection can perpetuate altruism. If there is an 'altruism gene' or complex of genes that influences an organism's behavior to be helpful and protective of relatives and their offspring, this behavior also increases the proportion of the altruism gene in the population, because relatives are likely to share genes with the altruist due to common descent.

Altruists may also have some way to recognize altruistic behavior in unrelated individuals and be inclined to support them. Although it is generally true that humans tend to be more altruistic toward their kin than toward non-kin, the relevant proximate mechanisms that mediate this cooperation have been debated see kin recognition , with some arguing that kin status is determined primarily via social and cultural factors such as co-residence, maternal association of sibs, etc.

Whatever the proximate mechanisms of kin recognition there is substantial evidence that humans act generally more altruistically to close genetic kin compared to genetic non-kin. Although interactions with non-kin are generally less altruistic compared to those with kin, cooperation can be maintained with non-kin via mutually beneficial reciprocity as was proposed by Robert Trivers. Direct reciprocity can lead to the evolution of cooperation only if the probability, w, of another encounter between the same two individuals exceeds the cost-to-benefit ratio of the altruistic act:.

Reciprocity can also be indirect if information about previous interactions is shared. Reputation allows evolution of cooperation by indirect reciprocity. Natural selection favors strategies that base the decision to help on the reputation of the recipient: studies show that people who are more helpful are more likely to receive help. The calculations of indirect reciprocity are complicated and only a tiny fraction of this universe has been uncovered, but again a simple rule has emerged.

One important problem with this explanation is that individuals may be able to evolve the capacity to obscure their reputation, reducing the probability, q, that it will be known. Trivers argues that friendship and various social emotions evolved in order to manage reciprocity. Evolutionary psychologists say that humans have psychological adaptations that evolved specifically to help us identify nonreciprocators, commonly referred to as 'cheaters.

Humans may have an evolved set of psychological adaptations that predispose them to be more cooperative than otherwise would be expected with members of their tribal in-group, and, more nasty to members of tribal out groups. Contact Booklover. Find a Store Franchising.

Study of a co-designed decision feedback equalizer,deinterleaver and decoder. Argentina in the crisis years, Broadcast journalism. This edition of the encyclopedia, containing 40, entries, is now in the public domain, and many of its articles have been used as a basis for articles in Wikipedia. Some articles have special value and interest to modern scholars as cultural artifacts of the 19th and early 20th centuries. The eleventh edition was assembled with the management of American publisher Horace Everett Hooper.

Hugh Chisholm, who had edited the previous edition, was appointed editor in chief, with Walter Alison Phillips as his principal assistant editor. Originally, Hooper bought the rights to the volume 9th edition and persuaded the British newspaper The Times to issue its reprint, with eleven additional volumes 35 volumes total as the tenth edition, which was published in Hooper's association with The Times ceased in , and he negotiated with the Cambridge University Press to publish the volume eleventh edition.

Though it is generally perceived as a quintessentially British work, the eleventh edition had substantial American influences, not only in the increased amount of American and Canadian content, but also in the efforts made to make it more popular. The initials of the encyclopedia's contributors appear at the end of selected articles or at the end of a section in the case of longer articles, such as that on China, and a key is given in each volume to these initials.

Some articles were written by the best-known scholars of the time, such as Edmund Gosse, J. Among the then lesser-known contributors were some who would later become distinguished, such as Ernest Rutherford and Bertrand Russell. Many articles were carried over from the 9th edition, some with minimal updating. Some of the book-length articles were divided into smaller parts for easier reference, yet others much abridged.

The best-known authors generally contributed only a single article or part of an article. Most of the work was done by journalists, British Museum scholars and other scholars. The eleventh edition introduced a number of changes of the format of the Britannica. It was the first to be published complete, instead of the previous method of volumes being released as they were ready.
