Final answer:
The combination of bipedalism in early humans led to increased cranial capacity, changes in diet and tool use, and expanding social relations. Bipedalism allowed for the development of more complex tools and the ability to carry and use them effectively. It also facilitated the expansion of territories and the establishment of more complex social networks.
Step-by-step explanation:
The combination of bipedalism in early humans resulted in several significant changes, including increased cranial capacity, changes in diet and tool use, and the expansion of social relations. Bipedalism allowed early humans to free their hands, leading to the development of more complex tools and the ability to carry and use them effectively. Additionally, bipedalism increased the size of the pelvic area, allowing for a larger brain, which in turn facilitated the development of advanced cognitive skills and problem-solving abilities.
For example, the adoption of bipedal locomotion enabled early humans to hunt more efficiently and pursue game over longer distances. This, combined with the ability to use tools, improved their ability to obtain food and survive in diverse environments. As a result, early humans were able to expand their territories and establish more complex social networks, leading to cultural advancements and the diversification of human groups.
