Final answer:
Homo habilis is notable for its bipedal locomotion and early tool use, but not for hunting large mammals or arboreal living.A) Bipedalism and walking upright
Step-by-step explanation:
Homo habilis is primarily associated with bipedalism and walking upright and scavenging and tool use. This species is considered one of the earliest in the genus Homo and exhibits significant evolutionary traits including longer legs and arched feet for efficient bipedal locomotion, as well as anatomical changes such as a larger brain size compared to australopithecines, and repositioning of the thumb which allowed for better grip and dexterity in tool-making. Hunting large mammals was not a primary characteristic of Homo habilis, and while they were bipedal, they were not exclusively tree-dwelling or arboreal.
