Solution
- Increase in cranial capacity is regarded as the most significant change as it leads to the expansion in the cerebellum and neocortex, areas which are associated with learning, conscious thought and reasoning.
- The development of the brain enabled hominids to make and use tools and fire, communicate using language, develop culture and society, adapt to new environments and, finally, to become self-aware and creative.
