Abstract

Wolff (2024) takes a comparative phylogenetic approach to study the evolution of dragline silk in 164 species of spiders, including both araneid and non-araneid species. Many structural and mechanical properties of dragline silk showed no correlations; however, both tensile strength and toughness correlated with birefringence-an indicator for the directional ordering of protein materials in the silk fibre. These properties do not seem to differ between web-building and non-web-building spiders; many spider families were found to include species that produce super-performing silk as well as species that produce weak-performing silk.

摘要：蛛形纲纲动物拖丝的进化在造网蜘蛛和不造网蜘蛛中显示出超强的拉伸性能。

Wolff（2024）采用比较系统发育的方法研究了164种蜘蛛（包括蛛形目和非蛛形目蜘蛛）的拖丝进化。拖丝的许多结构和力学性能没有相关性；然而，拉伸强度和韧性都与双折射有关，双折射是丝绸纤维中蛋白质材料定向排序的一个指标。这些属性在造网蜘蛛和不造网蜘蛛之间似乎没有区别；研究人员发现，许多蜘蛛科既包括产出高性能蛛丝的物种，也包括产出弱性能蛛丝的物种。
