TLDR
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.
Abstract
We review the evolution of domestic animals, emphasizing the effect of the earliest steps of domestication on its course. Using the first domesticated species, the dog (Canis familiaris), for illustration, we describe the evolutionary peculiarities during the historical domestication, such as the high level and wide range of diversity. We suggest that the process of earliest domestication via unconscious and later conscious selection of human-defined behavioral traits may accelerate phenotypic variations. The review is based on the results of a long-term experiment designed to reproduce early mammalian domestication in the silver fox (Vulpes vulpes) selected for tameability or amenability to domestication. We describe changes in behavior, morphology and physiology that appeared in the fox during its selection for tameability, which were similar to those observed in the domestic dog. Based on the data of the fox experiment and survey of relevant data, we discuss the developmental, genetic and possible molecular genetic mechanisms underlying these changes. We ascribe the causative role in evolutionary transformation of domestic animals to the selection for behavior and to the neurospecific regulatory genes it affects.

The “Domestication Syndrome” in Mammals: A Unified Explanation Based on Neural Crest Cell Behavior and Genetics

TL;DR: It is proposed that the domestication syndrome results predominantly from mild neural crest cell deficits during embryonic development, which can be readily explained as direct consequences of such deficiencies, while other traits are explicable as indirect consequences.

The self-domestication hypothesis: evolution of bonobo psychology is due to selection against aggression

TL;DR: The self-domestication hypothesis provides a plausible account of the origin of numerous differences between bonobos and chimpanzees, and note that many of these appear to have arisen as incidental by-products rather than adaptations.

The Sleep Disorder Canine Narcolepsy Is Caused by a Mutation in the Hypocretin (Orexin) Receptor 2 Gene

TL;DR: It is determined that canine narcolepsy is caused by disruption of the hypocretin (orexin) receptor 2 gene (Hcrtr2) and this result identifies hypocretins as major sleep-modulating neurotransmitters and opens novel potential therapeutic approaches for Narcoleptic patients.
