从进化的角度来看,信号通常应该是可靠或诚实的(Zahavi,1987; Johnstone,1997)。动物可以通过向潜在的配偶和其他竞争者,特别是经常为交配机会而激烈竞争的雄性,宣传其高竞争能力来获得许多优势(Andersson,1994)。动物通常更喜欢高质量的配偶,这将增加其后代的适应性,这既是因为遗传利益(通过良好的基因或费舍尔选择),也是因为高竞争力的父母通常提供更好的资源和保护。如果潜在的挑战者退出或以其他方式避免与具有高战斗能力的对手的侵略性遭遇,竞争者也将获得优势。因此,信号员面临着强大的选择压力,他们要向他人宣传自己的社会地位和竞争能力。然而,只有当这些信号是信号发送者竞争能力的可靠指标时,接收者才能从对这些信号的响应中获得优势。雌性与低质量的雄性交配,不诚实的信号高竞争能力将不会为他们的后代获得任何优势,而雄性退出与较贫穷的竞争对手的竞争,将处于不利地位。因此,在接收器上存在强烈的选择,以仅对抵抗欺骗的诚实信号做出响应,因此对于高质量的动物,在信号中提供这种可靠的信息,因为这些信息将有效地吸引配偶并阻止竞争者。
From an evolutionary viewpoint, signals generally should be reliable or honest (Zahavi, 1987; Johnstone, 1997). Animals can gain a number of advantages from advertising high competitive ability to potential mates and to other competitors, particularly males which often compete strongly for mating opportunities (Andersson, 1994). Animals often prefer high quality mates that will increase the fitness of their offspring, both because of genetic benefits (through good genes or Fisherian selection) and because parents of high competitive ability often provide better resources and protection. Competitors will also gain an advantage if potential challengers withdraw from, or otherwise avoid, aggressive encounters with an opponent of high fighting ability. There is thus strong selection pressure on signallers to advertise high social status and competitive ability to others. However, receivers will only gain an advantage from responding to such signals if these are reliable indicators of the signaller’s competitive ability. Females that mate with low quality males that dishonestly signal high competitive ability will gain no advantage for their offspring, while males that withdraw from agonistic encounters with poorer competitors will be disadvantaged. There is thus strong selection on receivers to respond only to honest signals that are resistant to cheating, and therefore for high quality animals to provide such reliable information in signals as these will be effective in attracting mates and deterring competitors.
