Drawings of Representational Images by Upper Paleolithic Humans and their Absence in Neanderthals Reflect Historical Differences in Hunting Wary Game

Richard G. Coss
University of California, Davis

ABSTRACT: One characteristic of the transition from the Middle Paleolithic to the Upper Paleolithic in Europe was the emergence of representational charcoal drawings and engravings by Aurignacian and Gravettian artists. European Neanderthals never engaged in representational drawing during the Middle and Early Upper Paleolithic, a property that might reflect less developed visuomotor coordination. This article postulates a causal relationship between an evolved ability of anatomically modern humans to throw spears accurately while hunting and their ability to draw representational images from working memory. Unlike Neanderthals, archaic and anatomically modern humans in sub-Saharan Africa adopted longer-range hunting practices using hand-cast spears as a compensation for the emergence of increasingly wary game. For Neanderthals, paleoclimatic fluctuations likely precluded consistent hunting of cold-adapted game, a property making game more approachable for close-range hunting with thrusting spears. As evidence of less historical wariness of humans, many of the species hunted by Neanderthals were eventually domesticated. Due to strong sources of natural selection on archaic and anatomically modern humans for effective hunting, the parietal cortex that integrates visual imagery and motor coordination expanded progressively, yielding the globular shape of the human cranium that is not evident in Neanderthals. To characterize how the cognitive properties employed for throwing spears and drawing line work are similar, the Upper Paleolithic drawings of animals in Chauvet cave, France, are discussed in the speculative context of how these artists engaged simultaneously in overt attention to guide their hand movements and covert attention to their mental images during the drawing process.

The Appeal of the Primal Leader: Human Evolution and Donald J. Trump

Dan P. McAdams
Northwestern University

ABSTRACT: Drawing on the distinction between dominance and prestige as two evolutionarily grounded strategies for attaining status in human groups, this essay examines an underappreciated feature of Donald Trump’s appeal to the millions of American voters who elected him president in 2016—his uncanny ability to channel primal dominance. Like the alpha male of a chimpanzee colony, Trump leads (and inspires) through intimidation, bluster, and threat, and through the establishment of short-term, opportunistic relationships with other high-status agents. Whereas domain-specific expertise confers status in the prestige paradigm, dominant leaders derogate expertise in order to establish a direct, authoritarian connection to their constituency. Trump’s leadership style derives readily from his personality makeup, which entails a combustible temperament mixture of high extraversion and low agreeableness, a motivational agenda centered on extreme narcissism, and an internalized life story that tracks the exploits of an intrepid warrior who must forever fight to win in a Hobbesian world of carnage.

ABSTRACT: How far has the Darwinian revolution come? To what extent have evolutionary ideas penetrated into the social sciences and humanities? Are the “science wars” over? Or do whole blocs of disciplines face off over an unbridgeable epistemic gap? To answer questions like these, contributors to top journals in 22 disciplines were surveyed on their beliefs about human nature, culture, and science. More than 600 respondents completed the survey. Scoring patterns divided into two main sets of disciplines. Genetic influences were emphasized in the evolutionary social sciences, evolutionary humanities, psychology, empirical study of the arts, philosophy, economics, and political science. Environmental influences were emphasized in most of the humanities disciplines and in anthropology, sociology, education, and women’s or gender studies. Confidence in scientific explanation correlated positively with emphasizing genetic influences on behavior, and negatively with emphasizing environmental influences. Knowing the current actual landscape of belief should help scholars avoid sterile debates and ease the way toward fruitful collaborations with neighboring disciplines.

INTRODUCTION TO THE FIRST ISSUE: Why We Need a Journal with the Title Evolutionary Studies in Imaginative Culture

Joseph Carroll
University of Missouri, St. Louis

Evolutionary Studies in Imaginative Culture is designed to make use of an opportunity that has only recently opened up for the social sciences and humanities. These fields now have before them the prospect of a synthesis that would produce, for the first time, a comprehensive and scientifically robust understanding of the human condition. That synthesis would immensely enrich both the humanities and the social sciences. It would ground the humanities on the bedrock of scientific fact, and it would consummate the explanatory potential in the evolutionary social sciences....
