Domesticated bodies

Humans are hypothesized to have undergone a process of self-domestication, associated with reduction of aggressive behavior and enhanced sociability. We have also undergone anatomical changes in our parietal cortex, which is crucial for body cognition and visuospatial integration. In a recent Opinion Paper published in Frontiers in Psychology, Ben Gleeson and I wonder whether these two factors, self-domestication and body cognition, may have reciprocal influences, or even share some evolutionary mechanisms. A first likely bridge is our heightened use of technology, which is strictly associated with our body-tool prosthetic capacity and with our special life-cycle (adolescence and creativity, longevity, post-reproductive stages, etc.). The concept of “tool” is considered, in this article, through functional and cognitive parameters. A second connection is the social system, because body cognition and the association cortex affect group size and social skills based on egocentric perspectives. Neural plasticity could represent an important organic link between these anatomical and behavioral aspects. The article is part of a volume dedicated to Self-Domestication and Human Evolution.

Visuospatial behaviours

After the perspective paper on visuospatial cognition and human evolution, and the review on visuospatial integration and the fossil record, we have now published a review article on visuospatial behaviors in archaeology. Here, we introduce and discuss parietal cortex evolution, embodiment, tool use and tool making, wayfinding, and the association between physical, chronological, and social spaces. A main target of cognitive archaeology is to test whether modern human cognition is due to a specific prosthetic capacity that enhances the functional relationships between body and technology, offloading brain functions and outsourcing information process to the enviroment. Something similar happens to … spiders! This chapter is part of a book dedicated to the Evolution of Primate Social Cognition (Springer).

    This week, we provide a new study of temporal lobe evolution in the Homo erectus hypodigm inferred from the middle cranial fossa (MCF) of the skull.

Some of the less tangible pains is the... Continue […]
