Which of the following features is NOT characteristic of H. habilis?

Homo habilis is typically characterized by a range of physical and anatomical features that display both primitive and more advanced traits compared to earlier hominins. One of its distinguishing features is the relatively longer arms compared to its legs, reflecting adaptations for climbing and partially arboreal lifestyles, similar to earlier hominins.

Focusing on the correct answer, the feature that is not characteristic of Homo habilis is the proportion of limbs, specifically the length of legs compared to arms. In fact, H. habilis exhibits shorter legs in relation to its arms. This body proportion suggests adaptations that are less suited for fully terrestrial locomotion and more for climbing, which aligns with the overall morphology of H. habilis as a transitional species.

Curved fingers indicate adaptations for grasping, as seen in arboreal species, and thus are characteristic of H. habilis. The small chewing complex refers to the less powerful jaw and smaller teeth, which reflect dietary changes and the use of tools for processing food. The ability to climb trees further emphasizes the species' connection to earlier hominins and their adaptability to both ground and arboreal environments.

Thus, the correct choice highlights a significant feature that does not align with the anatomical traits of Homo habilis
