Definition
[Bearbeiten | Quelltext bearbeiten]…
„Specifically, compared to their wild counterparts domesticated animals typically express repeated patterns of altered physiology, morphology and behaviour, a phenomenon known as the “domestication syndrome” (Darwin 1868; Hammer 1984). For example, domesticated mammals commonly express increased tameness, reduced brain size, depigmentation, floppy ears, curly tails and changes in hormonal profiles (Driscoll et al. 2009; Sánchez-Villagra et al. 2016, Figure 1). The repeated occurrence of suites of traits across a wide range of domesticated species seems unlikely to be caused by unique mutations, but rather to be a result of correlated traits driven by altered selection pressures during domestication (Trut 1999; Trut et al. 2009).” [1]
„The suite of traits is neither universal amongst species nor amongst all breeds of a given species (Sanchez-Villagra et al., 2016)“[2]
Geschichte
[Bearbeiten | Quelltext bearbeiten]„The search for an explanation of the DS began with the man who discovered the phenomenon (although he did not name it): Charles Darwin. He had been trying to develop a theory of the nature of heredity since at least the early 1850s […]“[2] „The term itself appears to have been first used in connection with a parallel set of observed commonalities amongst domesticated plants (Hammer, 1984) but was later applied to animals (Larson et al., 2014; Wilkins et al., 2014). (Some authors, however, prefer the term “domesticated phenotype” to avoid the implication of illness associated with the word “syndrome”, e. g. (Leach, 2003).)“[2]

- Reaktion auf Wilkins et al.: „the provocative hypothesis most recently articulated by Wilkins et al. [29] on a potential common developmental mechanism underlying all domestication in mammals deserves a closer look and a critical discussion.“ [4]
