Altered embryonic neural crest cell
- Altered embryonic neural crest cell (NCC) behaviour is a widely cited explanation for the domestication syndrome [ 1 ], a suite of shared, apparently associated, changes, observed in domesticated populations when compared to their wild ancestors or relatives.

Is there a phenotypic domestication syndrome?
Domestication syndrome refers to two sets of phenotypic traits that are common to either domesticated plants [1] [2] or domesticated animals. [3] Domesticated animals tend to be smaller and less aggressive than their wild counterparts, they may also have floppy ears, variations to coat color, a smaller brain, and a shorter muzzle.
Here, we propose that the domestication syndrome results predominantly from mild neural crest cell deficits during embryonic development. 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.

Jul 1, 2014 · The general combination of traits in domesticated mammals is an ensemble that we will refer to as the “domestication syndrome” (DS) (adopting a term used for domesticated crop plants, e.g., Brown et al. 2008 ). We list its core components in Table 1.

May 22, 2020 · Domestication syndrome is a term that describes the permanent changes that appear in plants and animals as a result of domestication. Some of the behavioral changes fueled by the domestication syndrome include tameness and increased docility. Darwin is credited for the discovery of the domestication syndrome.
Jun 3, 2019 · Domestication is hypothesized to drive correlated responses in animal morphology, physiology and behaviour, a phenomenon known as the domestication syndrome. However, we currently lack...

Charles Darwin, while trying to devise a general theory of heredity from the observations of animal and plant breeders, discovered that domesticated mammals possess a distinctive and unusual suite of heritable traits not seen in their wild progenitors. Some of these traits also appear in domesticated birds and fish.
Sep 8, 2020 · While many different traits have been selected in many different domestic species, a universal domestication syndrome would be much more restricted, including: (i) changes in behaviour (tameness); (ii) changes in body size and composition; (iii) changes in brain size and composition; and (more recently and less stringently) (iv) changes in ...
