在计算猎物所受力的脚本中发现了一个编码错误。此错误仅适用于附着的(类似软体动物的)猎物。误差的产生是因为在每个时间步定义猎物位置的矢量没有保持猎物的位置不变。其结果是，施加在猎物身上的力，即在猎物占据的位置上起作用的力，没有正确计算出来。因此，对类似软体动物的猎物进行的模拟并没有产生与特定表型特征组合相关的正确的最大力。我们已在更新的文章中更正了这一点，并重新进行了模拟和后续分析。图3、图4、图5和辅助材料分别进行了更新。拟合的GAM显示，所有的平滑和张量平滑都是显著的，R2=91.6%。梯度上升分析显示，地形不那么崎岖，只有少量的山峰(图3)。在描述与每个峰值相关的特征空间的主成分分析中，第一个维度解释了68%的方差，在到达峰值的时间和打击距离上有较强的正向载荷，而第二个维度解释了27.5%的方差，在公羊速度和峰值上有较强的正向载荷
A coding error was found in the script in which the force exerted on the prey was calculated. This error only applied to attached (‘mollusk-like’) prey. The error arose because the vector that defined the location of the prey at each time step did not keep the position of the prey fixed. The consequence was that the forces exerted on the prey, ie the forces in play at the position the prey occupied, were not correctly calculated. Thus, the simulations carried out for mollusk-like prey did not produce the correct maximum force associated with the specific combination of phenotypic traits. We have corrected this in the updated article, and re-done the simulations and the subsequent analyses. Figures 3, 4, and 5, and the supplementary material have been updated respectively.The fitted gam revealed that all smooths and tensor smooths were significant, with r2= 91.6%. The gradient ascent analysis revealed a less rugged landscape with a small number of peaks (Fig. 3). In the PCA carried out to characterize the trait space associated with each peak, the first dimension explained 68% of the variance with strong positive loadings on time to peak jaw protrusion and strike distance, while the second dimension explained 27.5% of the variance with strong positive loadings on ram speed and peak
