"This is East Africa 2 million years ago. ”

The two of them, who have a wealth of historical knowledge, are doing the commentary. Wuchai likes to listen to it, and this knowledge is quickly absorbed and organized in her brain. In fact, at this time, Kai did the same as her, but the difference was that he used all the memory devices. The robo-soldier's memory is very much in it

There are many things, but there is still no live explanation like this. This is a machine soldier who loves to learn.

"They resemble modern humans, no different from other creatures that share a habitat. ”

Everyone looked at the apes in amazement, one mother slapped the child in her arms and lulled him to sleep, and the other grabbed the crazy child and prevented him from running. A couple of old apes stayed away from them, and they needed to be quiet, while a sturdy fellow beat his chest vigorously and courted a female next to him. After a while, another male ape came over, patting his muscular chest and challenging the previous one. The two guys stepped aside, picked an open space, and fought.

"Are they dueling?"

Degree asked. Daonan nodded.

"They often have such duels. ”

"Yes, the duel now comes from them. ”

Du looked at this duel from his ancestors, and the young man also had such a passion in his heart, a man's passion. It turns out that the duel is handed down by the ancestors, and when I go back, I have to find someone to duel for a while. He thought.

The old man was their leader, full of wisdom. He looked at them very lightly, as if he was accustomed to this.

"Don't look at such a leader, you need wisdom. At that time, the conditions were difficult, and leading a group of people to fight against the sky, the earth, and the animals, all of which required wisdom. Also, to grab food and territory with other clansmen, you also have to use wisdom. ”

"They are the ancestors of human beings, they know love and joy, friendship, and they will fight for power, just like chimpanzees and elephants. ”

Tao Nan said in a low voice, as if he was afraid of disturbing the ancestors of these human beings.

"Every animal has a genus, and so does Homo sapiens, and they have many members, just a bunch of apes. The closest thing to humans is the chimpanzee. ”

Wuchai approached the children who were playing in the woods, and followed the little master. He was still a little afraid of these strong, tall, four-legged ancestors. And those children are not afraid of their descendants at all, and even have some closeness.

A child held out his hand to them. Wuchai was about to reach out to shake it, but the child was led back by his mother. The kid turned back as he walked, smiling at Wuchai.

When you get to the next hole, you see people walking upright. They walked upright in the pristine forest, and among the animals full of feet on the ground, it was already very unusual.

"They are Homo erectus in Eastern Asia and have been around for two million years. ”

The two children were amazed.

"Humans have grown up for so long!"

"Although they walk upright, the rest of their habits are the same as those of apes on all fours. Because they're not Homo sapiens yet, they don't know how to use tools yet. ”

Kai quickly archived the knowledge that Daonan said in his memory. The difference between him and Wuchai is that when the sound is converted into words, these precious images are also stored in it.

This is a very precious material, the only real image of human progress in the world.

When you get to the next hole, it's an island surrounded by seawater. Lived on it were gnomes less than a meter tall, who were able to survive for so long in this era of food scarcity, thanks to their short stature and stature, which did not eat much because of their short stature.

A dwarf nimbly climbed up a tree to pick fruit, and below it were his children and women, who waited with their heads bowed. Others catch snakes on the ground. They knew the animal well and quickly caught one, which they immediately put in their mouths and chewed.

In an open field, a man was grinding another stone with a stone, and it seemed that he wanted to thin one end of the stone so that it could be used as a tool.

"Look, elephant!"

A small elephant scurried ahead. He was followed by several muscular men with rocks and sticks with sharpened heads.

"That's okay too!"

Degree said.

Wuchai pursed his lips, revealing displeasure.

There are other animals on the island, such as cattle and sheep, which are very short.

"When the sea was still very low, humans first arrived on the island of Flores, where it was easy to get to and from the land. Then the sea rose, and they were stranded on the island. When there is little food left, those who are tall and eat a lot of food quickly starve to death, while the smaller ones who don't need a lot of food survive. After several generations, the island of Loris became a dwarf. They are known as the Rorisians. ”

Seeing how cute those pocket animals are, I don't really want to play with them on the island.

"How dare you do this?"

Degree said.

The baby elephants also saw that there was no guessing. They approached her, sticking out their long noses, and held out their hands to them.

"It's so cute!"

Daonan looked at Wuchai and remembered that she had been playing with these animals since she was a child.

"Why can't you see them now?"

Du asked suddenly.

Donan didn't answer. The answer is already here.

"These dwarf people lived in harmony with them here, but later, when Homo sapiens arrived on the island, they were quickly exterminated. ”

Probably thinking about the scene when these cute animals were killed by Homo sapiens, Wuchai's face darkened.

"The law of nature is natural selection, survival of the fittest. “

"Actually, Homo sapiens is not only a branch of Homo sapiens, but also many relatives, and there are many races of people in the whole world, at least six different kinds of people. And Homo sapiens, that is, man, is only one of them. Historically, the coexistence of multiple people has been the norm. “

Tao Nan continued to give them popular science.

"What about the other relatives?"

Degree asked. Donan didn't answer the question right away.

"One thing these genera have in common is that their brains are significantly larger than those of other animals. Therefore, people are the smartest. “

Entering another hole, this is a different scene. A large and ferocious animal, the lion, was eating its prey, and dozens of jackals were waiting next to it.

"Don't look at these jackals, although they are afraid of lions, they are also very vicious, and humans cannot afford to provoke them. ”

Daonan said.

When the big guy had finished eating and burped away, the jackals rushed up and ate the leftovers. Not far from them, someone was waiting. When the jackals had eaten and left, they dared to go up. At this time, there is no meat, only bones.

"What's going on here?"

Everyone thinks.

These people are smart, they have been prepared for a long time. Pick up the stone, smash the bone, and suck the marrow inside.

"Too smart, our ancestors!"

"At this time, humans are still very weak and cannot subdue large animals, even these medium-sized ferocious animals cannot be subdued, and can only eat what they have left. “

South Road Road.

"It's very unfair, the law of the jungle. ”

"Nature is also fair, the lion is strong, the sheep run fast. Otherwise, only those large animals will be left, without food, and they will not starve to death. It's a complete food chain. In the past, humans were at the bottom of the food chain, but later, with fire, Homo sapiens learned to make tools, and humans stood at the top of the food chain and became the masters of the earth. “
