目的纹身不是一种进化的行为，但它可能是强调免疫健康的一种表型策略。表型策略是一种看似代价高昂，但作为不受遗传学约束的自然选择的磨练过程而高频率发生的性状或行为。纹身是一种古老的做法，在世界范围内越来越受欢迎，但它涉及伤害身体，这似乎违反直觉，因为它挑战免疫系统，使人更容易受到感染。但是，纹身可能代表一个昂贵的诚实的信号，健身的“加大赌注”在一个时代的卫生或手段，以刺激免疫系统的方式，提高和突出潜在的fitness.Materials and MethodsWe调查了这一假设，通过评估细菌的杀伤活性（BKA）在两个研究中收集的唾液样本纹身（N= 40）。我们比较了以前的纹身经验（身体纹身的程度和纹身所花的时间）到BKA之前和之后得到一个新的纹身。结果纹身经验积极预测纹身后BKA（β= 0.48，p = 0.01），表明纹身经历多的人比纹身经历少的人有相对更直接和活跃的免疫反应。这可以帮助防止未来的皮肤损伤。
ObjectivesTattooing is not an evolved behavior, but it may be a phenotypic gambit to highlight immunological health. Phenotypic gambits are traits or behaviors that appear costly but occur at high rates as a honing process of natural selection not constrained by genetics. Tattooing is an ancient practice that is increasing in popularity worldwide, but it involves wounding the body, which seems counterintuitive because it challenges the immune system and makes one more susceptible to infection. But tattooing may represent a costly honest signal of fitness by “upping the ante” in an era of hygiene or a means to stimulate the immune system in a way that improves and highlights underlying fitness.Materials and MethodsWe investigated this hypothesis by assessing bacteria killing activity (BKA) in saliva samples collected during two studies of tattooing (N= 40). We compared previous tattoo experience (extent of body tattooed and hours spent being tattooed) to BKA before and after getting a new tattoo.ResultsTattoo experience positively predicts post‐tattoo BKA (β= 0.48,p= 0.01), suggesting that people with more tattoo experience have a relatively more immediate and active immune response than those with less tattoo experience.DiscussionTattoo experience may elevate innate immunological vigilance, which could aid in protecting against future dermal insults.
