Final answer:
True, H. erectus hominins were different from their more ancient African predecessors, exhibiting more modern human-like characteristics in body size, brain capacity, and behaviors.
Step-by-step explanation:
Most analyses have shown that H. erectus hominins represent a different hominin than their more ancient African predecessors. The statement is True. H. erectus appeared approximately 1.8 million years ago and exhibited characteristics more similar to modern humans than earlier hominins such as H. habilis. With a larger brain capacity (775 to 1,100 cubic centimeters), less sexual dimorphism, and a body size comparable to that of modern humans, H. erectus clearly differs from earlier species. This species was also the first to migrate out of Africa, reaching as far as Asia and Europe, and to use fire and hunt, signifying major advancements in hominin development.
