There is a crisis of readership for work in our field, as in many other academic disciplines. One of its causes is a pathological form of the professionalism that we so greatly value. “Hyperprofessionalism” is a disease whose symptoms include self‐referentiality, self‐absorption, and a narrowing of intellectual focus. This essay describes some features and consequences of hyperprofessionalism in the history of science and offers a modest suggestion for a possible cure.

Chimpanzee and hunter-gatherer intergroup aggression differ in important ways, including humans having the ability to form peaceful relationships and alliances among groups. This paper nevertheless evaluates the hypothesis that intergroup aggression evolved according to the same functional principles in the two species—selection favoring a tendency to kill members of neighboring groups when killing could be carried out safely. According to this idea chimpanzees and humans are equally risk-averse when fighting. When self-sacrificial war practices are found in humans, therefore, they result (...) from cultural systems of reward, punishment, and coercion rather than evolved adaptations to greater risk-taking. To test this “chimpanzee model,” we review intergroup fighting in chimpanzees and nomadic hunter-gatherers living with other nomadic hunter-gatherers as neighbors. Whether humans have evolved specific psychological adaptations for war is unknown, but current evidence suggests that the chimpanzee model is an appropriate starting point for analyzing the biological and cultural evolution of warfare.

Fossils have been traded for centuries. Over the past two hundred years the market has developed into an organized enterprise, with fossils serving multiple functions as objects of scientific study, collectors' items, and investments. Finding fossils, digging them up or purchasing them, transporting, studying, and conserving them, and putting them on display was and still is expensive. Since the early nineteenth century, funding bodies, academic institutions and museums, philanthropists, dealers, collectors, amateurs, and professional paleontologists have constituted elaborate networks driven by (...) collaboration, necessity, ambition, accolades, and capital to generate knowledge and produce geological artifacts, increasing our understanding of the natural world, advancing careers and institutions, and contributing to personal fortunes. The emergence of paleoanthropology as a scientific discipline around 1900 generated a scientific focus on the human story that was easy to sell. The scarcity of ancient human remains made it close to impossible for a commercial market to evolve, yet finding them required serious funding. Elaborate schemes for financing expeditions and excavations went hand in hand with individual aspirations, patronage, philanthropy, networks, and alliance building, as concession rights and access to sponsors were objects of regular political intrigues and often bitter disputes.

ArgumentIn the 1920s there were still very few fossil human remains to support an evolutionary explanation of human origins. Nonetheless, evolution as an explanatory framework was widely accepted. This led to a search for ancestors in several continents with fierce international competition. With so little fossil evidence available and the idea of a Missing Link as a crucial piece of evidence in human evolution still intact, many actors participated in the scientific race to identify the human ancestor. The curious case (...) ofHomo gardarensisserves as an example of how personal ambitions and national pride were deeply interconnected as scientific concerns were sometimes slighted in interwar palaeoanthropology.
