翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Weapon (biology) ： ウィキペディア英語版 Weapon (biology) Weapons are traits that are used by males to fight one another off for access to mates. A mate is won in battle either by a male chasing off a fellow competitor or killing it off, usually leaving the victor as the only option for the female to reproduce with.〔Krebs, J. R., and Nicholas B. Davies. "Sexual Selection, Sperm Competition and Sexual Conflict." An Introduction to Behavioral Ecology. 4th ed. Oxford: Blackwell Scientific Publications, 2012.〕 However, because stronger organisms, whether mentally or physically, are usually favored in combat, this also leads to the evolution of stronger organisms in species that use combat as a way to secure mates.〔"Charles Darwin & Evolution." Charles Darwin & Evolution. Apr. 2014. .〕 Examples of weapons include the antlers bucks use to fight one another off when competing for females. ==References== 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「Weapon (biology)」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.
