尽管200多年来人们认识到一些微观后生动物在隐生状态下生存的环境条件远远超过了自然界的环境条件，但这一现象很少受到进化生物学家的关注。隐生生物表现出的过度环境抗性不能被视为当前进化生物学中的适应。相反，过度抗性可能是对干燥或其他自然发生的环境因素的耐受性的自然选择的副产品。干燥、代谢停滞、保护分子对干燥或冷冻细胞的有效稳定以及有效的DNA修复机制的综合作用，可能导致了对生物体的保护，使其免受远远超出自然界所经历的条件的影响。
Despite more than 200 yr of recognition that some microscopic metazoans survive environmental conditions far beyond those experienced in nature while in a cryptobiotic state, this phenomenon has received little attention from evolutionary biologists. The excess environmental resistance exhibited by cryptobiotic organisms cannot be viewed as an adaptation within current evolutionary biology. Rather, excess resistance may have evolved as a by‐product of natural selection for tolerance to desiccation or other naturally occurring environmental agents. The combined effects of desiccation, metabolic arrest, effective stabilization of dry or frozen cells by protectant molecules, and efficient DNA repair mechanisms may have led to a protection of the organism against conditions far beyond those experienced in nature.
