Final answer:
The statement that the Southeastern United States was an independent center for plant domestication is true, as indigenous peoples in this area domesticated various species, influencing early agriculture in the region.
Step-by-step explanation:
The statement that the region of the present-day Southeastern United States was likely one of the world's independent centers for plant domestication is true. Archaeological evidence suggests that indigenous peoples in this region were among the first to transition from a hunter-gatherer lifestyle to one that included the cultivation of native plants. This includes the domestication of various species such as sunflower, goosefoot, and marsh elder, contributing to the early development of agriculture in the Americas. Therefore, it is accurate to recognize the Southeastern United States as an independent center for early plant domestication.
