Final answer:
Foraging groups never adopted agriculture due to the suitability of hunting and gathering in their environment, the labor specialization required by agriculture, and the leisure time enjoyed by foragers compared to farmers.
Step-by-step explanation:
There are several reasons why foraging groups never adopted agriculture. One reason is that foraging provided a more suitable and practical means of survival in their specific environment. For example, the Indigenous peoples of Australia chose to continue hunting and gathering despite being in contact with groups practicing agriculture in New Guinea. Another reason is that agriculture required labor specialization, which meant devoting energy to farming and associated chores, leaving little time for other tasks. Additionally, foraging groups often had more leisure time compared to farmers.
