From my understanding, it sounds like this species is more advanced than others that coexist in the same timeline and perhaps ignite the changes in how following homo sapiens live their life. For one, H. erectus can adapt to specific environments, dietary practices, and inventions. According to the text, H. erectus depended on hunting, foraging, and other means to gather food, which led them to invent hunting and farming tools (Kottak 2022 pg. 161). Cooking is also an essential function that this group does. Like us today, we cook our food. H. erectus could have been the first to use fire to make it more consumable.
