ABOVE: FLICKR.COM, ZOOFANATIC A paper published yesterday (December 3) in Trends in Ecology and Evolution criticizes a famous experiment on fox taming and casts doubt on domestication syndrome, the idea that a variety of physical traits change when an animal goes from wild to tame.


of knowledge is a modern syndrome, consisting of the fact that all models of cognition and in an historical process of domestication. Over the last twenty years,.

It was first described in animals (although not named as such) by Charles Darwin [ 1 ]. The term itself, coined by botanists in the early 1900s [ 2, 3 ], was applied to animals in the 1980s [ 3 ]. domestication that comprise the domestication syndrome. They have also contributed to our knowledge of useful crop breeding traits, such as pathogen resistance, and of fundamen- tal biological processes, such as polyploidization. Another aspect of the domestication syndrome in common bean is a significant reduction of the number of nodes on the main stem accompanied by a small increase in internode length. The dwarfing mechanism in pea involves virtually the opposite approach, with the internode length, not the number of internodes, being affected by the substitution of le for Le .

This is known as "domestication syndrome." Now, researchers are pointing to a group of a cells called neural crest cells as the key to understanding domestication syndrome. 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 Se hela listan på sciencenetlinks.com The domestication syndrome of convergent traits proposed here for vegetatively propagated crops is, therefore, only preliminary. Significant focus on the genetic aspects of domestication has contributed to our understanding of the mechanisms and origins of many domesticates and key domestication traits. These changes, recognized as the domestication syndrome, are basic requirements for effective seed harvest and planting and higher grain yield that made cultivation practical and worthwhile.

By subjecting a population of foxes to selection for tameness alone, Dimitry Belyaev generated foxes that possessed a suite of characteristics that mimicked those found across domesticated species. This ‘domestication syndrome’ has been a central focus of research into the biological pathways 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 Quantitative trait loci related to domestication syndrome traits have been identified in various crop species. QTL mapping has shown that domestication of crop species was based on changes at a small number of loci with a relatively large effect (Koinange et al., 1996; Cai and Morishima, 2002). These could be true given the fact that selection The “Domestication Syndrome” in Mammals: A Unified Explanation Based on Neural Crest Cell Behavior and Genetics.

Join us for a shallow dive into the basics of domestication including why we can't ride zebras and how some people think we domesticated ourselves. A domestication syndrome of convergent evolutionary traits has been proposed for sexually reproduced crops that can be tracked in the archaeobotanical record through the emergence of non-shattering cultivars and, to a lesser extent, through increased seed size (Fuller et al., 2014, 2018). Explaining domestication syndrome Wilkins and colleagues now propose a hypothesis that links the development of the neural crest with the body changes that accompany domestication.
