What was the approximate brain size of H. habilis?

The approximate brain size of Homo habilis is typically estimated to be around 600 cubic centimeters (cc). This hominin species is known for its larger brain size compared to earlier human ancestors, indicating a significant evolutionary step. H. habilis is often associated with the development of early stone tools and is considered one of the first members of the genus Homo. The increase in brain size is thought to correlate with more complex behaviors and cognitive abilities, which are critical for survival and adaptation in their environment. Brain size increases in the lineage of Homo are generally associated with advancements in tool-making and social organization, making this 600 cc estimate important for understanding the cognitive evolution of hominins.
