Domestication syndrome is a term often used to describe the suite of phenotypic traits arising during domestication that distinguish crops from their wild ancestors. 2014 refer to as the ‘‘domestication syndrome’’). Most explanations focus on particular traits, while neglecting others, or on the possible selective factors involved in domestication rather than the underlying developmental and genetic causes of these traits. Human protection drives the emergence of a new coping style in animals. The researchers argue that the domestication process selects for pre-existing variants in a number of genes that affect neural crest development.

The blue tube indicates the approximate position of the neural crest in the early embryo, and the blue arrows indicate pathways of neural crest cell migration. So what makes the finding so intriguing is that these cells are hypothesized to be key players in what is known as the domestication syndrome, wherein domesticated animals tend not only to be behaviorally calm, but also share a suite of morphological and anatomical … Most of the modified traits, both morphological and physiological, can be readily explained as direct consequences of such deficiencies, while other traits are explicable as indirect consequences. Sánchez-Villagra MR, Geiger M, Schneider RA. Comparing the phenotypic characteristics of modern and prehistoric man, it is clear that during their recent evolutionary past, humans also went through a process of self-domestication with a simultaneous prolongation of the period of socialization. Irving-Pease E.K., Ryan H., Jamieson A., Dimopoulos E.A. Sahlén P, Yanhu L, Xu J, Kubinyi E, Wang GD, Savolainen P. Genome Biol Evol. Scientists call this “domestication syndrome” — the idea that breeding out aggression inadvertently leads to physical changes, including floppier ears, shorter muzzles and snouts, curlier tails, paler fur, smaller brains, and more. Most of the modified traits, both morphological and physiological, can be readily explained as direct consequences of such deficiencies, while other traits are explicable as indirect consequences.
