Editor's Commentary:
"At present, Biologia Futura offers the chance to read about a provocative new theory, called “active social domestication"(Pörtl & Jung, 2019), wherein, the social environment induced neurophysiological changes in the foundation stock of hypothetical dog ancestors, which would cause an epigenetic cascade effect that led to a relatively rapid unfolding of the so-called domestication syndrome (Meaney & Szyf, 2005; Trut et al., 2009). As with any markedly new theory, heated scientific discussions will likely follow, we also have to add that “active social domestication”provides an option for a new genre of empirical tests to unfold.
