We propose that human self-domestication favored the emergence of a less aggressive phenotype in our species, more precisely phenotype prone to replace (reactive) physical aggression with verbal aggression. In turn, the (gradual) transition to verbal aggression and to more sophisticated forms of verbal behavior favored self-domestication, with the two processes engaged in a reinforcing feedback loop, considering that verbal behavior entails not only less violence and better survival, but also more opportunities to interact longer and socialize with more conspecifics, ultimately (...) enabling the emergence of more complex forms of language. Whereas in the case of self-domestication sexual selection has been proposed to work against physical aggression traits, in the case of verbal insult the selection has been proposed to work in favor of verbal aggression. The tension between these two seemingly opposing forces gets resolved/alleviated by a tendency to replace physical aggression with verbal aggression, and with verbal behavior more generally. This also helps solve the paradox of the Self Domestication Hypothesis regarding aggression, more precisely why aggression in humans has been reduced only when it comes to reactive aggression, but not when it comes to proactive aggression, the latter exhibiting an increase with the advent of modern language. We postulate that this feedback loop was particularly important during the time period before 50 kya, arguably between 200 kya and 50 kya, when humans were not fully modern, neither in terms of their skull/brain morphology and their behavior/culture, nor in terms of their self-domestication. The novelty of our approach lies (i) in giving an active role to early forms of language in interacting with self-domestication processes; (ii) in providing specific linguistic details and functions of this early stage of grammar (including insult and humor); (iii) in supplying neurobiological, ontogenetic, and clinical evidence of a link between (reactive) aggression and (reactive) verbal behavior; (iv) in identifying a variety of proxies of the earlier stages in evolution among cognitive disorders; and (v) in identifying specific points of contact and mutual reinforcement between these two processes (self-domestication and early language evolution), including reduction in physical aggression and stress/tension, as well as sexual selection.

Language evolution has long been researched. I will review a number of broad, emerging research directions which arguably have the potential to contribute to our understanding of language evolution. Emerging topics in genomics and neurolinguistics are explored, and human-specific levels of braincase globularity – and the broader process of self-domestication within which globularity seems capable of being encapsulated – will be argued to be the central pillars of any satisfactory and interdisciplinary model of language evolution.

In this article, focusing on the building blocks of art with its concomitant role and meaning, we commence with a brief evolutionary overview of the origin of land vertebrates, which culminated in the rise of our species as we view it. We then review three iconic phases of human evolution, colloquially designated as the Neanderthals, the San and the Cro-Magnons, as manifested by their artistic endeavours. We are well aware that the Cro-Magnons are currently regarded as not sufficiently distinct from (...) modern Homo sapiens to be separately designated. Therefore, the terms ‘anatomically modern humans’ or ‘early modern humans’ are suggested for these inhabitants of the Upper Palaeolithic as they shared an anatomical resemblance with us but still lacked the full complement of behavioural attributes that typify ourselves. This particular selection was chosen because these groups have partially overlapped historically, yet each represents a distinctive approach to the artistic impulse. Subsequently, we consider more contemporary developments regarding human art intertwined with our interpretation of art’s role and meaning. Then, we briefly discuss a broader account of the evolution of art in which these three phases are firmly based and through which our understanding of and engagement with the evolutionary development of these stages are elucidated and complemented. In conclusion, particular views about language and the role and meaning of art are confirmed. Particular views about language and the role and meaning of art are endorsed and supplemented by an extensive body of relevant literature.Contribution: This article explores the evolution of art and its accompanying role and meaning in an intersectional and interdisciplinary manner that fits well with the intention of this unique collection on the building blocks of our past, present and future and with the nature of this journal and our ongoing engagement with HTS Teologiese Studies/Theological Studies.

This article, in its first part, summarizes Noam Chomsky’s ideas about human nature and their ethico-political consequences, language and its origin and the scope and limitations of experimental science. As a result, there will emerge the portrait of a great scientist without prejudices and a true and honest freethinker. Then, on the second part, and based on the author C. S. Lewis, a proposal will be made about the possible existence of an infused rational soul in humans and how it (...) could connect with the linguist’s ideas with respect to the origin of language. It will also serve to supply with some realism Chomsky’s too optimistic view about human nature. (shrink)

Scientific advancement is inextricably linked to cultural advancement, and historically the arts have worked hand in hand with technological change. This essay explores some of the connections that exist between science, technology, and the arts, privileging instances where technological change resulted in new forms of artistic creation. Although the role of the arts in contemporary society has ebbed in comparison to that of technology and science, the essay argues that quality, meaningfulness, and longevity are key components in how the arts (...) can retain cultural value in today’s technocentric world. It explores significant instances from the history of music and visual art as the authors make the case that the methods of science and art are both distinct yet commensurate in their ability to shape the values and ideas of contemporary society.
