The role of the arts has become crucial to understanding the origins of “modern human behavior,” but continues to be highly controversial as it is not always clear why the arts evolved and persisted. This issue is often addressed by appealing to adaptive biological explanations. However, we will argue that the arts have evolved culturally rather than biologically, exploiting biological adaptations rather than extending them. In order to support this line of inquiry, evidence from a number of disciplines will be (...) presented showing how the relationship between the arts, evolution, and adaptation can be better understood by regarding cultural transmission as an important second inheritance system. This will allow an alternative proposal to be formulated as to the proper place of the arts in human evolution. However, in order for the role of the arts to be fully addressed, the relationship of culture to genes and adaptation will be explored. Based on an assessment of the cognitive, biological, and cultural aspects of the arts, and their close relationship with ritual and associated activities, we will conclude with the null hypothesis that the arts evolved as a necessary but nonfunctional concomitant of other traits that cannot currently be refuted.

With this contribution I explore the relationship between attention development in modern archers and attention as a cognitive requirement for ancient bow hunting – a techno-behaviour that may have originated sometime between 80 and 60 thousand years ago in sub-Saharan Africa. Material Engagement Theory serves as a framework for the inextricable interrelatedness between brain, body and mind, and how practicing to use bimanual technologies shapes aspects of our cognition, including our ability to pay attention. In a cross-disciplinary approach, I use (...) cognitive-motor neuroscience to demonstrate the role of attention in modern archery and highlight brain regions that are activated or ‘pressured’ during aiming with attention. One of these areas, the precuneus together with the default mode network, serves as neurological hub for accurate bimanual material engagement practiced over a distance. The likely development of the precuneus, in tandem with the unique globularisation of the human skull, can be traced in the Homo sapiens fossil record since about 160 thousand years ago, reaching the modern range by around 100 thousand years ago within a continuum of brain modification. Variation in human neuro-genetic adaptations since our split from the Denisovan and Neanderthal groups further suggest differences in attention as a cognitive trait between recent big-brained humans. I suggest that these observations may serve as bridging theory for understanding how some aspects of the sapient ability to pay attention was developed. (shrink)

The cerebral cortex controls our most distinguishing higher cognitive functions. Human‐specific gene expression differences are abundant in the cerebral cortex, yet we have only begun to understand how these variations impact brain function. This review discusses the current evidence linking non‐coding regulatory DNA changes, including enhancers, with neocortical evolution. Functional interrogation using animal models reveals converging roles for our genome in key aspects of cortical development including progenitor cell cycle and neuronal signaling. New technologies, including iPS cells and organoids, offer (...) potential alternatives to modeling evolutionary modifications in a relevant species context. Several diseases rooted in the cerebral cortex uniquely manifest in humans compared to other primates, thus highlighting the importance of understanding human brain differences. Future studies of regulatory loci, including those implicated in disease, will collectively help elucidate key cellular and genetic mechanisms underlying our distinguishing cognitive traits. (shrink)
