Ancient humans used tools to obtain food

Originally it was mainly scavenging and eating wild fruits. It's miserable, and then I learned to use tools for some easier hunting, and then I learned to make tools, so that I can do some more difficult but rewarding hunting, and then later, I found that some wild grains can be artificially planted, and humans began to farm, and since then they no longer have to migrate for food, and began to settle down, and then then humans have mastered the domestication technology, and some wild animals have been domesticated and artificially cultivated, so as to enrich human nutrition**, The evolution of the brain is also becoming more and more perfect.

Hope my answer will be helpful to you!

We know that primitive man, who had just come out of the animal state, could be used as an instrument of labor only by his hands and feet, with the exception of his hands, or occasionally with the help of branches or stones. For this reason, primitive man's food acquisition activities were initially limited to the acquisition and possession of natural products to sustain their lives, so most of their food was taken from the plant kingdom.

The leaves, fruits, bark, stems, roots, and tubers of the trees are at most only to hunt young beasts.

With insects only. Subsequently, after countless years and centuries, primitive man knew how to use man-made faculties (i.e., tools of labour) as instruments of power, adapted to his ultimate purpose, and acted on objects of familiarity to strengthen or supplement the efficacy of his own faculties. For example, to strike at a distance, he uses a club to extend his bottom arm; To strengthen the boxing, he holds a sharp stone.

The invention of these tools, no matter how primitive, but with them, primitive man was able to hunt wild beasts.

and important labour materials for improving food.

Thanks to the invention of tools, although the range of food for primitive people was expanded from picking plants to hunting animals, it was not possible to mix and enjoy the collected things in order to use fire at that time. Therefore, all the natural objects caught are just eaten alive, only the hard shell of the bottom of the fruit is peeled off with teeth and hands before eating, or the small animals caught are torn into small pieces in advance, and then eaten raw.

The most primitive time: fruit picking, group hunting.

Redevelopment: Hunting with sticks or stones.

Later: learned to use sharp stones to cut prey.

Later: Roast food over fire (first with natural fire, such as a wildfire caused by thunder, some wild animals will be burned to death.) Later invented drilling wood for fire).

Continue to develop: If there is more prey, do it when you can't finish eating.

Circle. Raising (this is how dogs, sheep, etc. start in captivity).

Later: ...... with bows, arrows, spears, etc

Gathering and hunting wild plants and animals was the most important method of obtaining food for our ancestors. But feeding on plants and hunting animals is not an easy task. Which plants and animals are edible and which are not?

What do they look like and how do you identify them? What kind of places do edible plants or animals live? These questions have already touched on the morphology, taxonomy and ecological knowledge of plants and animals.
