Evaluating the self‐domestication hypothesis of human evolution

A scenario in which the morphological byproducts of domestication can act as an honest signal of reduced xenophobia is suggested and the neural crest hypothesis for domestication has great explanatory power but it is difficult to test.

Hypotheses for the Evolution of Reduced Reactive Aggression in the Context of Human Self-Domestication

It is concluded that the evolution of language-based conspiracy was the key factor initiating and maintaining self-domestication in H. sapiens, because it is the most convincing mechanism for explaining the selective pressure against individually powerful fighters.

Did Dog Domestication Contribute to Language Evolution?

This work hypothesizes about a parallel domestication of humans and dogs, and more specifically, about a positive effect of the authors' interaction with dogs on human self-domestication, and ultimately, on aspects of language evolution, through the mechanisms involved in the control of aggression.

Survival of the Friendliest : Homo sapiens Evolved via Selection for Prosociality

The challenge of studying human cognitive evolution is identifying unique features of our intelligence while explaining the processes by which they arose. Comparisons with nonhuman apes point to our

The “tolerant chimpanzee”—towards the costs and benefits of sociality in female bonobos

The results support the hypothesis that predicts that females trade off feeding opportunities for safety against male aggression, and an integrated view of cooperation and competition over access to the key resources food and mates, both within and between the sexes are tested.

Comparative analyses of the Pan lineage reveal selection on gene pathways associated with diet and sociality in bonobos

Novel evidence of selection in genetic regions that aid in starch digestion (AMY2) along with support for two genetic predictions related to self‐domestication processes hypothesized to have occurred in the bonobo are found.

In reviewing comparative, developmental, neurobiological, and paleoanthropological research, compelling evidence emerges for the predicted relationship between unique human mentalizing abilities, tolerance, and the domestication syndrome in humans.

Human Social Evolution: Self-Domestication or Self-Control?

It is suggested that what underlies human social evolution is selection for socially mediated emotional control and plasticity, and further illustrates the significant differences between humans and domesticates, thus challenging the notion of human self-domestication.

Animal evolution during domestication: the domesticated fox as a model

Changes in behavior, morphology and physiology that appeared in the fox during its selection for tameability were similar to those observed in the domestic dog, and the developmental, genetic and possible molecular genetic mechanisms underlying these changes are discussed.

Differential changes in steroid hormones before competition in bonobos and chimpanzees

In anticipation of an identical competition, bonobo and chimpanzee males showed differential endocrine shifts, perhaps due to differences in perception of the situation, that is, viewing the event either as a stressor or a dominance contest.

A comparison of temperament in nonhuman apes and human infants.

This study compared the reaction of bonobos, chimpanzees, orangutans, and 2.5-year-old human infants to novel objects and people - as a measure of their shyness-boldness, a key temperamental trait.

The study of intraspecies behavioural diversity of bonobos is in its infancy, so ecological differences must be considered.

Comparisons among human infants, bonobos, chimpanzees, and orangutans on both social and physical problem-solving tasks demonstrate that human infants are unique for their early emerging social cognitive skills, which facilitate participation in cultural interactions.

Application of the heterochrony framework to the study of behavior and cognition

It is found that bonobos exhibit developmental delays relative to chimpanzees in several aspects of their social behavior and cognition, and this contributes to understanding behavioral and cognitive differences between adults of these two species and to knowledge of hominid evolution in general.
