翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Self-domestication ： ウィキペディア英語版 Self-domestication Self-domestication refers to the process of adaptation of wild animals to humans, without direct human selective breeding of the animals. The term is also used to refer to biological processes in the evolution of humans and human culture. ==In animals== Wild animals may ''self-domesticate'' when tame behaviour enhances their survival near humans. Tolerating or even enjoying the close approach of humans in order to feed near them, and a lessening of natural adult aggression, are two aspects of tameness. An environment that supports the survival of tame animals can lead to other changes in behaviour and appearance as well. Smaller skulls on tame animals have been noticed in other species. Noticing that a dog's skull looks like that of a juvenile wolf, Richard Wrangham goes on to say that "this leads to the thought that species can self-domesticate."〔 Other characteristics that are associated with juvenility – barking and meowing (sounds used by wolf cubs and kittens of large felines, respectively, to communicate with their parents), increased playfulness and reduced aggression, and increased eagerness to learn – are seen in tame animals. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Self-domestication」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
