Model of the
Active Social Domestication of Dog

NEW: Pörtl D, Jung C. Physiological pathways to rapid prosocial evolution - highlighting the role of epigenetics & retrosposons in dog domestication.Biologia Futura Vol 70, Issue 2 (publ. 30.07.2019; open access; Editor-in-Chief: Adam Miklosi)

"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."
