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.
The latter is thought to result from reduction in the size and function of the adrenal glands as well as from reduced levels of the fight-or-flight stress hormones which they produce. According to ...
Aug 24, 2016 · Traits modified in domesticated mammals generally include changes in ear size, shape, and stiffness; shorter snouts and smaller jaws; smaller teeth; and a reduced brain: specifically, the amygdala ...
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. Here, we propose that the domestication syndrome results predominantly from mild neural crest cell deficits during embryonic development.

Dec 22, 2020 · Darwin observed that all domesticated mammals share a set of common morphological, physiological, and behavioral traits that cannot be seen in their wild ancestors. Today, the domestication syndrome in mammals encompasses about fifty different phenotypic traits that a domesticated species has in relation to its wild ancestors.

Sep 3, 2016 · Aggression—along with its opposite, given selection for docility in domestication—is a key behavioural factor in "domestication syndrome." Aggressive behaviour is frequent in SZ, and may be ...
Mar 9, 2011 · The domestication of a plant species refers to the various genetic modifications to a wild progenitor which have been selected as the plant form has been modified to meet human needs (Doebley et al. 2006). Studying domestication provides a glimpse of the history of the selection and improvement made by our forebears over several thousands of ...
