Which feature is most indicative of the Homo habilis species compared to earlier hominins?

The feature most indicative of Homo habilis compared to earlier hominins is the increased cranial capacity. This species shows a noticeable expansion in the size of the brain relative to its body size, reflecting advancements in cognitive abilities and the development of more complex behaviors. The larger brain size in Homo habilis suggests a greater capacity for problem-solving, tool-making, and possibly even social interaction, as these skills became increasingly vital to survival in changing environments.

In contrast, earlier hominins possessed smaller cranial capacities, which limited cognitive development. This evolutionary change is significant as it marks a transition towards more advanced hominin species, ultimately paving the way for later species such as Homo erectus and Homo sapiens.
