Anthropology, and by extension archaeology, has had a long-standing interest in evolution in one or several of its various guises. Pick up any lengthy treatise on humankind written in the last quarter of the nineteenth century and the chances are good that the word evolution will appear somewhere in the text. If for some reason the word itself is absent, the odds are excellent that at least the concept of change over time will have a central role in the discussion. (...) After one of the preeminent (and often vilified) social scientists of the nineteenth century, Herbert Spencer, popularized the term in the 1850s, evolution became more or less a household word, usually being used synonymously with change, albeit change over extended periods of time. Later, through the writings of Edward Burnett Tylor, Lewis Henry Morgan, and others, the notion of evolution as it applies to stages of social and political development assumed a prominent position in anthropological disc- sions. To those with only a passing knowledge of American anthropology, it often appears that evolutionism in the early twentieth century went into a decline at the hands of Franz Boas and those of similar outlook, often termed particularists. However, it was not evolutionism that was under attack but rather comparativism— an approach that used the ethnographic present as a key to understanding how and why past peoples lived the way they did (Boas 1896).

Niche construction is the process whereby organisms, through their activities and choices, modify their own and each other’s niches. By transforming natural-selection pressures, niche construction generates feedback in evolution at various different levels. Niche-constructing species play important ecological roles by creating habitats and resources used by other species and thereby affecting the flow of energy and matter through ecosystems—a process often referred to as “ecosystem engineering.” An important emphasis of niche construction theory is that acquired characters play an evolutionary role (...) through transforming selective environments. This is particularly relevant to human evolution, where our species has engaged in extensive environmental modification through cultural practices. Humans can construct developmental environments that feed back to affect how individuals learn and develop and the diseases to which they are exposed. Here we provide an introduction to NCT and illustrate some of its more important implications for the human sciences. (shrink)

The behavioral sciences have flourished by studying how traditional and/or rational behavior has been governed throughout most of human history by relatively well-informed individual and social learning. In the online age, however, social phenomena can occur with unprecedented scale and unpredictability, and individuals have access to social connections never before possible. Similarly, behavioral scientists now have access to “big data” sets – those from Twitter and Facebook, for example – that did not exist a few years ago. Studies of human (...) dynamics based on these data sets are novel and exciting but, if not placed in context, can foster the misconception that mass-scale online behavior is all we need to understand, for example, how humans make decisions. To overcome that misconception, we draw on the field of discrete-choice theory to create a multiscale comparative “map” that, like a principal-components representation, captures the essence of decision making along two axes: aneast–westdimension that represents the degree to which an agent makes a decision independently versus one that is socially influenced, and anorth–south dimensionthat represents the degree to which there is transparency in the payoffs and risks associated with the decisions agents make. We divide the map into quadrants, each of which features a signature behavioral pattern. When taken together, the map and its signatures provide an easily understood empirical framework for evaluating how modern collective behavior may be changing in the digital age, including whether behavior is becoming more individualistic, as people seek out exactly what they want, or more social, as people become more inextricably linked, even “herdlike,” in their decision making. We believe the map will lead to many new testable hypotheses concerning human behavior as well as to similar applications throughout the social sciences. (shrink)

Archaeologists have proposed that behavioral knowledge of a tool can be conceptualized as a “recipe”—a unit of cultural transmission that combines the preparation of raw materials, construction, and use of the tool, and contingency plans for repair and maintenance. This parallels theories in cognitive psychology that behavioral knowledge is hierarchically structured—sequences of actions are divided into higher level, partially independent subunits. Here we use an agent-based simulation model to explore the costs and benefits of hierarchical learning relative to holistic learning, (...) where entire behavioral sequences are learned in an all-or-nothing fashion, and diffusionist learning, where actions are completely independent. Hierarchical learning is favored under the reasonable assumptions that learning is associated with some degree of both error and cost, and that behavior can be grouped into subunits that repeat in one or more tool recipes. These general predictions can be tested in the archaeological and ethnographic record. Recent advances in evolutionary developmental biology have revealed a number of parallels between the hierarchically structured, recipe-like organization of behavioral knowledge that we examine here and the manner in which biological organisms develop.

Given the numerous parallels between the archaeological and paleontological records, it is not surprising to find a considerable fit between macroevolutionary approaches and methods used in biology – for example, cladistics and clade-diversity measures – and some of those that have long been used in archaeology – for example, seriation. Key, however, is recognizing that this methodological congruence is illusory in terms of how evolution has traditionally been viewed in biology and archaeology. (Published Online November 9 2006).

The plot of Iphigenia in Tauris is usually thought to be Euripides' own invention. Its basic assumption can be found in Proclus' summary of the Cypria, viz. that a deer was substituted for Iphigenia during the sacrifice at Aulis and that she herself was removed to the land of the Tauri. Her later rescue by Orestes and Pylades, however, cannot be traced with probability to any work of art or literature earlier than Euripides' play. In this play, in which Orestes (...) recognizes and then saves the sister whom he had long thought dead, it is assumed that her replacement by a deer went unseen by those present at the sacrifice. The sequel which this assumption allowed Euripides to invent is original only in a limited sense, since it bears the imprint of several familiar story types. These types include the following: the murder of a kinsman is narrowly averted by a recognition; a reunion is followed by an intrigue; and a maiden is rescued. Each is used elsewhere by Euripides. The first two, for example, are found in Cresphontes, the second in Electra, and the third in Andromeda. Correspondences of this sort, based on plot patterns, will naturally gain in interest if it can be shown that they throw light on a play's meaning or on the process that led to its creation. The student of dramatic plots, however, soon discovers that analogies between them are easy to draw and can be quickly multiplied. (shrink)

Humanist sociologists are activists rooted in the reality of history and change and guided by a concern for the 'real life' problems of equality, peace, and social justice. They view people as active shapers of social life, capable of creating societies in which everyone's potential can unfold. Alfred McClung Lee introduces this volume with 'Sociology: Humanist and Scientific' and develops the theme that a sociology that is humanist is also scientific. The other nine selections are grouped into four parts: 'The (...) Individual and Social Life;' 'Social Institutions: Technology, Science, and Formal Organization;' 'Political Structures: Issues of Justice and Equality;' and 'Methodological Critiques and Counterproposals.'.

The belief that primitive men lived like beasts and that civilisation developed out of these brutal origins is found in numerous ancient authors, both Greek and Latin. It forms part of certain theories about the beginnings of culture current in late antiquity. These are notoriously difficult to trace to their sources, but they already existed in some form in the fifth century b.c. One idea common to these theories is that of progress, and for this reason a fragment of Xenophanes (...) is sometimes cited as their remote prototype: ‘The gods did not reveal all things to men from the beginning; instead, by seeking, men discover what is better in time’. Mainly on the strength of this fragment, Ludwig Edelstein devoted the first chapter of his book The Idea of Progress in Classical Antiquity to Xenophanes, and W. K. C. Guthrie has even declared that there is good reason to attribute to him a fuller account of progress, one that would include details found in later authors who speak of the early life of mankind. One of these details is the statement that the life of primitive men was ‘brutal’ or ‘beastlike’ . In these authors the implication of that term varies from ‘unschooled in the basic crafts’ to ‘inhumanly violent and bloodthirsty’. In one sense or the other it is repeatedly encountered in ancient references to this subject. Accounts of primitive brutishness which make use of the word θηριώδης (or θηριωδς can be found in the Suppliants of Euripides, in the Hippocratic treatise On Ancient Medicine, in three passages of Diodorus, one of which is thought by some to contain Democritean doctrine, in four passages of Isocrates, in a fragment from a satyr-play Sisyphus which the ancient sources attribute variously to Euripides and to Critias, in a fragment of Athenion, in a second-century inscription, in Plutarch, in Tatian, in Themistius, and in a scholion to Euripides.

We agree that the emergence of cumulative technological culture was tied to nonsocial cognitive skills, namely, technical-reasoning skills, which allowed humans to constantly acquire and improve information. Our concern is with a reading of the history of cumulative technological culture that is based largely on modern experiments in simulated settings and less on phenomena crucial to the long-term dynamics of cultural evolution.

We propose using a bi-axial map as a heuristic for categorizing different dynamics involved in the relationship between quality and popularity. The east–west axis represents the degree to which an agent’s decision is influenced by those of other agents. This ranges from the extreme western edge, where an agent learns individually (no outside influence), to the extreme eastern edge, where an agent is influenced by a large number of other agents. The vertical axis represents how easy or difficult it is (...) for an agent to discern the relative quality of available choices. When a case study is located on the map, it becomes easier to select the range of tools to use for understanding and predicting the relation between quality and popularity. (shrink)

A conventional processing workflow favors only the specular reflections, reducing or removing other wavefield interactions. These specular reflections are unsuitable for directly imaging sharp corners, such as those in fault zones and pinch outs; therefore, diffractions are used instead in a technique known as diffraction imaging. Plane-wave destruction is a well-established method for removing reflections and imaging diffractions. However, this method assumes a gently variable slope; therefore, it fails to remove energy in areas that do not follow this assumption such (...) as curved interfaces. To remove the remnant energy in these areas and thus enhance the overall interpretability of the diffraction images, we have adopted a simple spatial-variable filter in the frequency-wavenumber f-k domain based on the calculated dip field used for PWD, applied post PWD. To demonstrate the method, we have examined this on a range of synthetic data, complex synthetic data, and real data. The created diffraction images have then been interpreted to evidence the benefit of diffraction imaging in seismic interpretation, helping to delineate pinch outs, faults, and rugose surfaces.

In the study reported here we examined the impact of population size and two proxies of risk of resource failure on the diversity and complexity of the food-getting toolkits of hunter–gatherers and small-scale food producers. We tested three hypotheses: the risk hypothesis, the population-size hypothesis, and a hypothesis derived from niche construction theory. Our analyses indicated that the toolkits of hunter–gatherers are more affected by risk than are the toolkits of food producers. They also showed that the toolkits of food (...) producers are more affected by population size than are the toolkits of hunter–gatherers. This pattern is inconsistent with the predictions of both the risk hypothesis and the population-size hypothesis. In contrast, it is consistent with the predictions of the niche construction hypothesis. Our results indicate that niche construction has affected the evolution of technology in small-scale societies and imply that niche construction must be taken into account when seeking to understand technological variation among food producers and the technological changes that occurred in association with the various transitions to farming that have occurred over the last 10,000 years.

While new generations of implantable brain computer interface devices are being developed, evidence in the literature about their impact on the patient experience is lagging. In this article, we address this knowledge gap by analysing data from the first-in-human clinical trial to study patients with implanted BCI advisory devices. We explored perceptions of self-change across six patients who volunteered to be implanted with artificially intelligent BCI devices. We used qualitative methodological tools grounded in phenomenology to conduct in-depth, semi-structured interviews. Results (...) show that, on the one hand, BCIs can positively increase a sense of the self and control; on the other hand, they can induce radical distress, feelings of loss of control, and a rupture of patient identity. We conclude by offering suggestions for the proactive creation of preparedness protocols specific to intelligent—predictive and advisory—BCI technologies essential to prevent potential iatrogenic harms.

Doctors have an ethical and legal duty to respect patient confidentiality. We consider the basis for this duty, looking particularly at the meaning and value of autonomy in health care. Enabling patients to decide how information about them is disclosed is an important element in autonomy and helps patients engage as active partners in their care.Good quality data is, however, essential for research, education, public health monitoring, and for many other activities essential to provision of health care. We discuss whether (...) it is necessary to choose between individual rights and the wider public interest and conclude that this should only rarely be necessary. The paper makes some recommendations on practical steps which could help ensure that good quality information is available for work which benefits society and the public health, while still enabling patients’ autonomy to be respected.

Forensic evaluations of insanity have recently borne witness to an influx of neuroimaging methods, especially structural and functional magnetic resonance imaging and positron emission tomography, to assist in the development of explanations that help to excuse legal responsibility for criminal behavior. The results of these scanning methods have been increasingly introduced in legal settings to offer or support a clinical diagnosis that in turn suggests that an individual was incapable of knowing right from wrong, or to pinpoint brain dysfunction suggestive (...) of an inability to control behavior. This paper examines how neuroimaging has been employed in insanity evaluations. After addressing the contentious use of neuroimaging scans in insanity evaluations and synthesizing relevant research, we conclude that such scans presently hold limited applicability for forensic determinations of insanity. Furthermore, they can in some cases distract the trier of fact, potentially leading to erroneous conclusions. (shrink)

This review summarizes and critiques the empirical ethical decision-making literature from 1996-2003. One hundred and seventy-four articles were published in top business journals during this period. Tables are included that summarize the findings by dependent variable - awareness, judgment, intent, and behavior. We compare this review with past reviews in order to draw conclusions regarding trends in the ethical decision-making literature and to surface directions for future research.

Presents the views of eminent scientists on current problems in biology.
