9311139 Kirkpatrick Several species of lizards from the South Pacific have green blood. This green coloration is the result of the accumulation of the bile pigment biliverdin. Bile pigments are toxic to virtually all vertebrates producing the pathological condition known as jaundice. An understanding of how these lizards are able to withstand large concentrations of biliverdin may provide insight into the pathological nature of bile pigments in other vertebrates including humans. This same group of lizards has evolved several different types of adhesive toe pads. These toe pads are so adhesive that they can climb on smooth vertical surfaces such as glass. By measuring the adhesive abilities of different microstructures for different species we can understand the relationship between different morphologies and mechanisms of adhesion. Knowledge of the evolutionary relationships of these lizards is critical to understanding patterns of morphological and physiological evolution. ***

9311139柯克帕特里克（Kirkpatrick）来自南太平洋的几种蜥蜴有绿血。这种绿色是胆汁色素双脂蛋白积累的结果。胆汁颜料对几乎所有产生称为黄疸病的病理状况的脊椎动物都是有毒的。了解这些蜥蜴如何能够承受大量的biliverdin可能会深入了解包括人类在内的其他脊椎动物中胆汁色素的病理性质。同一组蜥蜴已经进化了几种不同类型的粘合剂脚趾垫。这些脚趾垫是如此的粘合剂，以至于它们可以在光滑的垂直表面（例如玻璃）上爬上。通过测量不同物种的不同微结构的粘附能力，我们可以理解不同形态和粘附机制之间的关系。对这些蜥蜴的进化关系的了解对于理解形态学和生理进化的模式至关重要。 ***
