Final answer:
Sustainable resource management was NOT a common practice among early humans.
Step-by-step explanation:
The answer to the question is d) Sustainable resource management.
Early humans relied heavily on sustainable resource management to survive. They gathered fruits, nuts, berries, and roots, and hunted and trapped wild animals. They also fished in rivers and lakes. Sustainable resource management allowed them to meet their basic needs while ensuring the resources were not depleted.
On the other hand, cannibalism, human sacrifice, and ritualistic warfare were practices that were more commonly observed among early humans. These practices were influenced by cultural beliefs and rituals and were not considered ethical by modern standards.
