'Humanlike' ways of thinking evolved 1.8 million years ago
By using highly advanced brain imaging technology to observe modern humans crafting ancient tools, a neuroarchaeologist has found evidence that human-like ways of thinking may have emerged as early as 1.8 million years ago. Ref. Source 3x.
It is hard to say really when men actually began to think like humans. It had to be somewhere when they started to think as a group when in hunting and finding safe shelter that they could defend. As this would have shown an awareness than just going from one place to another in the quest to eat and survive.
KN,
It may not be just hunting and finding shelter for safety. The great apes hunt together and look for shelter for safety that they can defend against other groups of great apes. They even make and use tools. But they are the simplest forms or tools. I can see where they are going with this, that it was all the things you listed plus learning to make more advanced tools, to think about what a tool needed to do and look like to be able to do its function that started us on the path to being what we are today.
