The evolutionary continuity between the prespeech functions of premotor cortex and its new linguistic functions, the main thesis of MacNeilage's target article, is confirmed by the recent discovery of “mirror” neurons in monkeys and a corresponding action-observation/action-execution matching system in humans. Physiological data (and other considerations) appear to indicate, however, that brachiomanual gestures played a greater role in language evolution than MacNeilage would like to admit.

Despite some sound basic assumptions, Wilkins & Wakefield portray a Homo habilis too linguistically sophisticated to fit in with the subsequent fossil record and thereby lose a reasoned explanation for human innovativeness. They err, too, in accepting a single-level model of conceptual structure and in deriving initial linguistic units from calls, a process far more dubious than the derivation of home-sign from naive gesture.

Wilkins & Wakefield (1995) provide a thoughtful contribution to our understanding of language origins. In this commentary I attempt to define the relationship between object-manipulation and primate brain function further by reviewing research on aimed throwing and the production and use of stone tools by tufted capuchin monkeys (Cebtis apella). I propose that examining the relation between brain function and object-manipulation inCebuswill provide insight into the preconditions of language in our hominid ancestors.

There are a number of competing hypotheses about human evolution. For example, Homo habilis and Homo erectus could have existed together, or one could have evolved from the other, and paleontological evidence may allow us to decide between these two hypotheses (see, e.g., Spoor et al., 2007). For most who work on the biology of human behavior, there is no question that human behavior is in some large part a product of evolution. But, there are competing hypotheses (...) in this area as well. Some claim that human behavior is produced by a collection of psychological mechanisms, for the most part, and that these mechanisms are adaptations that arose in the Pleistocene Epoch (e.g., Tooby & Cosmides, 1992; Buss, 2007). The claim is important and testable (although, more difficult to test than the above mentioned hypotheses about origins); but importantly, it is only one among many hypotheses about the evolutionary origins of human behavior. While I think that there may be components of our behavior that are best explained by appealing to processes or mechanisms that arose in the Pleistocene, I think that human behavior is a result of evolutionary processes both much older and more recent than the Pleistocene. I also maintain that much of human behavior, and the mechanisms underlying it, could still be subject to evolutionary.. (shrink)

The strong predominance of right-handedness appears to be a uniquely human characteristic, whereas the left-cerebral dominance for vocalization occurs in many species, including frogs, birds, and mammals. Right-handedness may have arisen because of an association between manual gestures and vocalization in the evolution of language. I argue that language evolved from manual gestures, gradually incorporating vocal elements. The transition may be traced through changes in the function of Broca's area. Its homologue in monkeys has nothing to do with vocal control, (...) but contains the so-called “mirror neurons,” the code for both the production of manual reaching movements and the perception of the same movements performed by others. This system is bilateral in monkeys, but predominantly left-hemispheric in humans, and in humans is involved with vocalization as well as manual actions. There is evidence that Broca's area is enlarged on the left side in Homo habilis, suggesting that a link between gesture and vocalization may go back at least two million years, although other evidence suggests that speech may not have become fully autonomous until Homo sapiens appeared some 170,000 years ago, or perhaps even later. The removal of manual gesture as a necessary component of language may explain the rapid advance of technology, allowing late migrations of Homo sapiens from Africa to replace all other hominids in other parts of the world, including the Neanderthals in Europe and Homo erectus in Asia. Nevertheless, the long association of vocalization with manual gesture left us a legacy of right-handedness. Key Words: cerebral dominance; gestures; handedness; hominids; language evolution; primates; speech; vocalization. (shrink)

Hypotheses regarding the selective pressures driving the threefold increase in the size of the hominid brain since Homo habilis include climatic conditions, ecological demands, and social competition. We provide a multivariate analysis that enables the simultaneous assessment of variables representing each of these potential selective forces. Data were collated for latitude, prevalence of harmful parasites, mean annual temperature, and variation in annual temperature for the location of 175 hominid crania dating from 1.9 million to 10 thousand years ago. (...) We also included a proxy for population density and two indexes of paleoclimatic variability for the time at which each cranium was discovered. Results revealed independent contributions of population density, variation in paleoclimate, and temperature variation to the prediction of change in hominid cranial capacity (CC). Although the effects of paleoclimatic variability and temperature variation provide support for climatic hypotheses, the proxy for population density predicted more unique variance in CC than all other variables. The pattern suggests multiple pressures drove hominid brain evolution and that the core selective force was social competition. (shrink)

This target article presents a plausible evolutionary scenario for the emergence of the neural preconditions for language in the hominid lineage. In pleistocene primate lineages there was a paired evolutionary expansion of frontal and parietal neocortex (through certain well-documented adaptive changes associated with manipulative behaviors) resulting, in ancestral hominids, in an incipient Broca's region and in a configurationally unique junction of the parietal, occipital, and temporal lobes of the brain (the POT). On our view, the development of the POT in (...) our ancestors resulted in the neuroanatomical substrate consistent with the ability for representations in modality-neutral association cortex and, as a result of structure-imposing interaction with Broca's area, the hierarchically structured Evidence from paleoneurology and comparative primate neuroanatomy is used to argue that Homo habilis (2.5–2 million years ago) was the first hominid to have the appropriate gross neuroanatomical configuration to support conceptual structure. We thus suggest that the neural preconditions for language are met in H. habilis. Finally, we advocate a theory of language acquisition that uses conceptual structure as input to the learning procedures, thus bridging the gap between it and language. (shrink)

I will, first, outline what we currently know about the last 4 million years of human evolutionary history, from bipedal but small‐brained Australopithecus to modern Homo sapiens, our species, through the prolific toolmaker Homo habilis and the continent wanderer Homo erectus. I shall then identify anatomical traits that distinguish us from other animals and point out our two kinds of heredity, the biological and the cultural.Biological inheritance is based on the transmission of genetic information, in humans (...) very much the same as in other sexually reproducing organisms. But cultural inheritance is distinctively human, based on transmission of information by a teaching and learning process that is in principle independent of biological parentage. Cultural inheritance makes possible the cumulative transmission of experience from generation to generation. Cultural heredity is a swifter and more effective (because it can be designed) mode of adaptation to the environment than the biological mode. The advent of cultural heredity ushered in cultural evolution, which transcends biological evolution.I will, finally, explore ethical behavior as a model case of a distinctive human trait, and seek to ascertain the causal connections between human ethics and human biology. My conclusions are that (1) moral reasoning—that is, the proclivity to make ethical judgments by evaluating actions as either good or evil—is rooted in our biological nature; it is a necessary outcome of our exalted intelligence, but (2) the moral codes that guide our decisions as to which actions are good and which ones are evil are products of culture, including social and religious traditions. This second conclusion contradicts those evolutionists and sociobiologists who claim that the morally good is simply that which is promoted by the process of biological evolution. (shrink)

The common ancestor of modern humans and the great apes is estimated to have lived between 5 and 8 Myrs ago, but the earliest evidence in the human, or hominid, fossil record is Ardipithecus ramidus, from a 4.5 Myr Ethiopian site. This genus was succeeded by Australopithecus, within which four species are presently recognised. All combine a relatively primitive postcranial skeleton, a dentition with expanded chewing teeth and a small brain. The most primitive species in our own genus, Homo (...) habilis and Homo rudolfensis, are little advanced over the australopithecines and with hindsight their inclusion in Homo may not be appropriate. The first species to share a substantial number of features with later Homo is Homo ergaster, or ‘early African Homo erectus’, which appears in the fossil record around 2.0 Myr. Outside Africa, fossil hominids appear as Homo erectus‐like hominids, in mainland Asia and in Indonesia close to 2 Myr ago; the earliest good evidence of ‘archaic Homo’ in Europe is dated at between 600–700 Kyr before the present. Anatomically modern human, or Homo sapiens, fossils are seen first in the fossil record in Africa around 150 Kyr ago. Taken together with molecular evidence on the extent of DNA variation, this suggests that the transition from ‘archiac’ to ‘modern’ Homo may have taken place in Africa. (shrink)

An adequate interpretation of concept of the propensity to communicate will thus lead us to interpret in this concept a possible formalization of the notion of the specious present, introduced into the field of psychology by William James at the end of the 19th Century. In this chapter, the authors introduce some aspects of the concept of time that their model operates under. While situating the actors in relation to each other in the network space, their propensity to communicate also (...) indexes the future opportunities that are open to them by their past trajectories. The authors conclude with a discussion of a supposed “ancestrality's paradox”, according to which such a primacy would pay no heed to ignoring events located in a temporality prior to the appearance of any life on earth, and well before that of Homo habilis.

Stone hurts—and not simply because rocks so easily become missiles. The lithic offers a blunt challenge to our belief that humans matter. Homo sapiens are a species perhaps 200,000 years old. Homo erectus and Homo habilis, two of our earliest ancestors, go back perhaps 2.5 million years. That seems a substantial span. If you were to count one number per second and never pause to sleep or eat, it would take about twelve days to reach one (...) million.

Within the historical times, which roughly corresponds with the Holocene epoch, the whole of mankind is believed to be a single species. Homo sapiens.

This response to continuing commentary addresses brain-hand relationships in Cebus apella (as introduced in West-ergaard's commentary), the evolutionary and acquisition parallels between music and language (suggested by Lynch), and the potential behavioral linguistic consequences of the evolutionary neurobiology in Australopithecus africanus and Homo habilis (discussed by Tobias). Finally, we reiterate the importance of well informed, multidisciplinary approaches to the study of the emergence of human species-specific cognition, especially linguistic capacity.

The work of Giorgio Agamben, one of Italy's most important and original philosophers, has been based on an uncommon erudition in classical traditions of philosophy and rhetoric, the grammarians of late antiquity, Christian theology, and modern philosophy. Recently, Agamben has begun to direct his thinking to the constitution of the social and to some concrete, ethico-political conclusions concerning the state of society today, and the place of the individual within it. In Homo Sacer, Agamben aims to connect the problem (...) of pure possibility, potentiality, and power with the problem of political and social ethics in a context where the latter has lost its previous religious, metaphysical, and cultural grounding. Taking his cue from Foucault's fragmentary analysis of biopolitics, Agamben probes with great breadth, intensity, and acuteness the covert or implicit presence of an idea of biopolitics in the history of traditional political theory. He argues that from the earliest treatises of political theory, notably in Aristotle's notion of man as a political animal, and throughout the history of Western thinking about sovereignty, a notion of sovereignty as power over "life" is implicit. The reason it remains merely implicit has to do, according to Agamben, with the way the sacred, or the idea of sacrality, becomes indissociable from the idea of sovereignty. Drawing upon Carl Schmitt's idea of the sovereign's status as the exception to the rules he safeguards, and on anthropological research that reveals the close interlinking of the sacred and the taboo, Agamben defines the sacred person as one who can be killed and yet not sacrificed—a paradox he sees as operative in the status of the modern individual living in a system that exerts control over the collective "naked life" of all individuals.

Published posthumously in 1908, Ecce Homo was written in 1888 and completed just a few weeks before Nietzsche’s complete mental collapse. Its outrageously egotistical review of the philosopher’s life and works—featuring chapters called Why I Am So Wise and Why I Write Such Good Books—are redeemed from mere arrogance by masterful language and ever-relevant ideas. In addition to settling scores with his many personal and philosophical enemies, Nietzsche emphasizes the importance of questioning traditional morality, establishing autonomy, and making a (...) commitment to creativity. Essential reading for students of philosophy, this unique memoir is crucial to an understanding of Nietzsche’s other works. (shrink)

Homo sapiens is entering a vital era in which the human-technology link is an inexorable trend. In this paper a look is taken as to how and why this is coming about and what exactly it means for both the posthuman species Homo technologicus and its originator Homo sapiens. Clearly moral and ethical issues are at stake. Different practical experimentation results that relate to the theme are described and the argument is raised as to why and how (...) this can be regarded as a new species. A picture is taken of the status of cyborgs as it stands today but also how this will change in the near future, as the effects of increased technological power have a more dramatic influence. An important ultimate consideration is whether Homo technologicus will act in the best interests of Homo sapiens or not. This paper concludes that the answer is clear. (shrink)

Heuristics are efficient cognitive processes that ignore information. In contrast to the widely held view that less processing reduces accuracy, the study of heuristics shows that less information, computation, and time can in fact improve accuracy. We review the major progress made so far: the discovery of less-is-more effects; the study of the ecological rationality of heuristics, which examines in which environments a given strategy succeeds or fails, and why; an advancement from vague labels to computational models of heuristics; the (...) development of a systematic theory of heuristics that identifies their building blocks and the evolved capacities they exploit, and views the cognitive system as relying on an “adaptive toolbox;” and the development of an empirical methodology that accounts for individual differences, conducts competitive tests, and has provided evidence for people’s adaptive use of heuristics. Homo heuristicus has a biased mind and ignores part of the available information, yet a biased mind can handle uncertainty more efficiently and robustly than an unbiased mind relying on more resource-intensive and general-purpose processing strategies.

Homo Juridicus focuses on the normative foundations underlying all socio-cultural formations. The book uses the concept of ''normativity'' in an inclusive sense. It includes law, but it is not limited to it. As such, it explores the various social and cultural forces that persuade, incite, seduce, influence, direct, restrain, repress or control behavior. It is a major interdisciplinary study cutting across several disciplines of social science, such as law, anthropology, sociology, psychology, linguistics and philosophy. Its primary audience is law (...) students, as well as the scholarly community across law and the social sciences. ''Isaak Dore is one of the very few scholars who straddles a broad range of legal and nonlegal disciplines. This important book deconstructs the idea of normativity in culture and illuminates it through various strains of thought in anthropology, sociology, psychology, linguistics and philosophy. Its grasp of these disciplines is impressive in terms of nuance, breadth, particularity and lucidity. It is a unique work, brilliantly executed, providing a rich background against which the promotion of social order through legal and nonlegal norms can be evaluated. It both provokes and compels one to think outside of the conventional structures and assumptions of law and social order. I know of no other work that offers the broad intellectual reach that this ambitious book presents.'' - Laura S. Underkuffler, J. DuPratt White Professor of Law, Cornell Law School. (shrink)

Since the beginning of business research and teaching, the basic assumptions of the discipline have been intensely debated. One of these basic assumptions concerns the behavioral aspects of human beings, which are traditionally represented in the construct of homo economicus. These assumptions have been increasingly challenged in light of findings from social, ethnological, psychological, and ethical research. Some publications from an integrative perspective have suggested that homo economicus embodies to a high degree dark character traits, particularly related to (...) the construct of psychopathy, representing individuals who are extremely self-centered and ruthless, without feelings of remorse or compassion. While a growing body of research notes such a similarity on a more or less anecdotal basis, this article aims to explore this connection from a more rigorous perspective, bridging insights from psychological, economic, and business research to better understand the potentially dark traits of homo economicus. The analysis shows that homo economicus is not simply some kind of psychopath, but specifically a so-called subclinical or Factor 1 psychopath, who is also referred to as a “corporate psychopath” in business research. With such an analysis, the paper adds an additional perspective and a deeper psychological level of understanding as to why homo economicus is often controversially debated. Based on these insights, several implications for academic research and teaching are discussed and reflected upon in light of an ethics of virtue and care. (shrink)

Technik bestimmt auf die mannigfaltigste Weise unser Leben und Zusammenleben. Obgleich sie von Platon und Aristoteles bis in das zwanzigste Jahrhundert in Einzelaspekten betrachtet worden ist, wurde sie erst in den letzten Jahrzehnten zu einem eigenständigen Gegenstand der Philosophie. Dennoch werden ihre philosophischen Probleme immer noch eher beiläufig behandelt.

Das Ziel ist eine Darstellung dieser faszinierenden philosophischen Fragen vor dem Hintergrund der Tradition. (shrink)

Ogni tentativo di ripensare le nostre categorie politiche deve muovere dalla consapevolezza che della distinzione classica fra zoé e bios, tra vita naturale ed esistenza politica (o tra l'uomo come semplice vivente e l'uomo come soggetto politico), non ne sappiamo piú nulla. Nel diritto romano arcaico homo sacer era un uomo che chiunque poteva uccidere senza commettere omicidio e che non doveva però essere messo a morte nelle forme prescritte dal rito. È la vita uccidibile e insacrificabile dell' 'uomo (...) sacro' a fornire qui la chiave per una rilettura critica della nostra tradizione politica. Quando la vita diventa la posta in gioco della politica e questa si trasforma in biopolitica, tutte le categorie fondamentali della nostra riflessione, dai diritti dell'uomo alla democrazia alla cittadinanza, entrano in un processo di svuotamento e di dislocazione il cui risultato sta oggi davanti ai nostri occhi. Seguendo il filo del rapporto costitutivo fra nuda vita e potere sovrano, da Aristotele ad Auschwitz, dall'Habeas corpus alle Dichiarazioni dei diritti, il libro di Agamben cerca di decifrare gli enigmi - prima di tutti il fascismo e il nazismo - che il nostro secolo ha proposto alla ragione storica. Fino a vedere, nel campo di concentramento, il paradigma biopolitico nascosto della modernità in cui città e casa sono diventate indiscernibili e la possibilità di distinguere tra il nostro corpo biologico e il nostro corpo politico ci è stata tolta una volta per tutte.
