Homo habilis
Artist's rendering of Homo habilis, which lived from 2 to 1.5 million years ago.
Homo habilis (2.0–1.5 mya) exhibits a combination of traits that suggest it engaged in both terrestrial and arboreal activities. While it possessed a large brain and small teeth, its skeletal anatomy retained several chimpanzee-like features indicative of climbing capabilities.1
Specifically, the features that suggest Homo habilis could still climb trees include:
- Long upper limbs: The species possessed relatively long arms, particularly the forearms.1
- Short femurs: The presence of short thigh bones is associated with arboreal adaptation.1
- Curved finger bones: This anatomical trait is a characteristic often linked to the ability to grasp and maneuver in trees.1
These traits represent a mélange of adaptations, leading some researchers to classify the species as Australopithecus habilis due to these retained primitive characteristics.1
