![]() The VPH is further modified as the nocturnal visual predation (NVP) hypothesis, considering that orbital convergence is particularly needed for nocturnal predators (e.g., ancestral euprimates) to improve image quality ( 5, 11– 15). The VPH proposes that euprimate characteristics such as orbital convergence and grasping hands and feet may have evolved as the result of the predatory adaptation of the ancestral primates in the arboreal setting ( 3– 5). ![]() Among the theories explaining the origin of euprimates ( 1, 2), there has been a continuing debate between two commonly cited hypotheses, the vision predation hypothesis (VPH) ( 3– 7) and the angiosperm-primate coevolution hypothesis ( 8, 9), as to whether insectivory or herbivory was the driving force of the evolution of distinctive euprimate morphological features ( 10). ![]() Therefore, our study suggests that the distinctive euprimate characteristics may have evolved as their specialized adaptation for ambush predation in arboreal environments.ĭiet is the key to understanding the origin of euprimates. In particular, our behavior experiment further shows that nonclaw climbing can significantly reduce noises, which could benefit the ancestral euprimates’ stalking to ambush their prey in trees. Given the carnivory of the CALP, along with the general observation that orbital convergence is largely restricted to ambush predators, our study suggests that the euprimate characteristics could have been more specifically adapted for ambush predation. Here, we used a molecular phyloecological approach to determine the diet of the common ancestor of living primates (CALP), and the results showed that the CALP had increased carnivory. ![]() Primates of modern aspect (euprimates) are characterized by a suite of characteristics (e.g., convergent orbits, grasping hands and feet, reduced claws, and leaping), but the selective pressures responsible for the evolution of these euprimate characteristics have long remained controversial. , * and Jiang Feng, Conceptualization, Investigation, Methodology, Project administration, Resources, Supervision Tinglei Jiang, Funding acquisition, Investigation, Methodology, Project administration, Resources, Supervision, Validation, Writing - review & editing, Hao Gu, Investigation, Methodology, Project administration,Ĭongnan Sun, Data curation, Investigation, Validation, Qingqing Li, Conceptualization, Data curation, Formal analysis, Funding acquisition, Investigation, Methodology, Project administration, Resources, Software, Supervision, Validation, Visualization, Writing - original draft, Writing - review & editing, Lu Bai, Conceptualization, Data curation, Formal analysis, Investigation, Methodology, Project administration, Resources, Supervision, Validation, Visualization, Writing - original draft, Writing - review & editing, , * Longcheng Fan, Conceptualization, Data curation, Formal analysis, Investigation, Methodology, Project administration, Resources, Software, Supervision, Validation, Visualization, Writing - original draft, Writing - review & editing, Yonghua Wu, Conceptualization, Data curation, Funding acquisition, Investigation, Methodology, Project administration, Resources, Supervision, Validation, Visualization, Writing - original draft, Writing - review & editing,
