This study uses viability selection simulations to predict the evolvability of primate species based on specialization of limb morphology. Following the author's predictions, more specialized limb morphologies were less responsive to selective pressures. This led to a slower transition toward new adaptive peaks. Specifically, evolvability of primate limbs was found to be associated with the degree of morphological integration, limb specialization, and body size.

肢体特化降低了可进化性

本研究使用生存能力选择模拟来预测基于肢体形态特化的灵长类物种的进化能力。根据作者的预测，更专业的肢体形态对选择压力的反应较小。这导致向新的自适应峰值过渡较慢。具体而言，发现灵长类四肢的进化能力与形态整合程度、四肢特化和体型有关。
