Final answer:
The claim that all archaeologists agree that Homo erectus was mainly a big game hunter is false; there is evidence of a varied diet that included significant gathering of plant foods.
Step-by-step explanation:
The statement that all archaeologists agree that Homo erectus was predominantly a big game hunter who rarely gathered wild plant foods is False. The archaeological record provides substantial evidence that early hominins, including Homo erectus, had a diverse diet that included a significant amount of gathered plant foods. Fossilized teeth of early hominids indicate omnivorous diets with well-worn molars adapted to gritty foods like nuts, seeds, and fruits. Additionally, anthropologists studying contemporary hunter-gatherer societies observe a significant emphasis on gathering, which likely reflects ancient practices. Furthermore, Homo erectus is associated with the use of tools, not just for hunting but presumably also for gathering, such as digging sticks and breaking stones, though such organic tools have not been preserved in the fossil record. Studies suggest that gathering and hunting practices were the primary means of subsistence for human ancestors for a vast majority of their evolutionary history.
