Outline of Final Research Achievements

Domesticated animals have shared properties of shorter head, weaker agressiveness, white spots, and higher stress registance. A hypothesis that can inclusively explain these characteristics is "neural crest" hypothesis of domestication. Because domesticaion selected less agressivness, neural crest cells that are involved in forming adrenal medulla which sythesizes corticosterone, migrate slower than wild types. This could resulted in phenotypes related with domestcation, because all phenotypes are related with neural crest cells. Bengalese finches had been domesticated over 250 years from wild white-rumped munias imported from China. We examined whether differences between the two strains might fit with the neural crest hypothesis. Although stress registance, white-spots, and telencephalic song control areas could be explained by the neural crest hypothesis, bill shapes, body size, and amygdala volue did not fit with the hypothesis.
