Metamorphosis pt. 3.2: Integration across Landscapes and Brain Regions

Fight Like An Animal

We continue the story of humanity's journey to modern thought and behavior, examining how a mosaic of both cultural and anatomical traits existed throughout Africa for ~200 thousand years. Then, this patchwork of cultures and anatomies fused, a process of integration that is also reflected in increasing brain connectivity. We see how isolated populations lose traits, but connected ones generate feedback loops of characteristically human tendencies: tolerance, social comprehension, communication, behavioral flexibility, and mobility all encourage one another. We also introduce the notion of the vocabulary of temperaments, the features such as neurotransmitters and brain regions shared by complex animal life, giving us a common language of rapid, novel responsiveness to environmental conditions, henceforth official Fight Like An Animal nomenclature.
