What is one potential limitation of the Grasping-Leaping Hypothesis?

The Grasping-Leaping Hypothesis proposes that certain characteristics in early primates evolved due to the need for adaptations to arboreal life, such as grasping and leaping between branches. One potential limitation of this hypothesis is that it inadequately addresses the role of other physical adaptations such as dentition (teeth) and morphology (the study of form and structure). While the hypothesis focuses primarily on the grasping and locomotor abilities of these primates, it does not explain how variations in dental structures or other physical traits may have contributed to their evolutionary success. This suggests that relying solely on the adaptations related to grasping and leaping overlooks important aspects of the broader evolutionary context and the diverse adaptations that primates possess.

In contrast, options discussing nocturnal adaptations, climate changes, or terrestrial behaviors may have their relevance but do not capture the specific shortcoming regarding a lack of consideration for dental and morphological traits within the framework of the hypothesis itself.
