By the time of entering the next cave, Homo sapiens had crossed the sea and came to the southern continent, a land surrounded by seas. The abundance of biological species here amazed and excited Homo sapiens. Their hard work and hard work have brought them great benefits.

The eyes are full of creatures that have never been seen before. There are kangaroos weighing 200 kilograms and two meters tall, with a bag on their chests, and the marsupial lion, which is a large predator and has a tiger-like body. On the ground, flightless birds are galloping, twice the size of an ostrich, koalas are in trees, and in forests there are huge two-incisor beasts, like two-ton wombats.

The animals were attached to the birds, and they all carried a bag on their bodies.

Wuchai and Du looked at these amazing and cute animals in amazement.

"Why is the species here so different from other places?"

The second child asked.

"This is due to the movement of the earth's crust, this land plate separated from the ancient continents relatively early, and the ocean became a natural barrier between it and other continents, preventing primitive animals from communicating with their genes, so many strange animals appeared. ”

It's also amazing.

Wuchai stared at them with curious eyes, and she imagined what it was like to sleep in their bags. As she thought so, a mother kangaroo approached her, and she had an extra baby kangaroo in her bag, and the little one smiled at her, and Wuchai reached out to tease her.

She began to worry about them.

These large animals seem to be behemoths, they seem fierce and terrifying, but they are not at all aggressive, and even gentle, and some of them are herbivores. In this peaceful and abundant environment, they did not know that they were about to be destroyed.

Here they are, a new bunch of interlopers. These Homo sapiens were overjoyed, it was truly a paradise for animals. Compared to all the places Homo sapiens have stayed in before, this is the most pleasant place to live.

"The plants and animals here have more than 12,000 species of plants, of which 9,000 species are not found in other countries, because there are no carnivorous predators, and many primitive organisms that have long been extinct on other continents are maintained.

At this time, a beautiful and showy flower came into everyone's eyes.

"It's called Eucalyptus rose, and it has a beautiful shape, unique flower shape, bright colors, and a long flowering period. ”

"It's a strange flower. ”

Degree saw the alternative of flowers.

"It's called a kangaroo claw, so named because the peduncle resembles a kangaroo's claw. ”

Growing up in the woods, Guess was blown away by them, she had never seen such a strange, velvety flower. She reached out to touch them, but she was afraid to touch the velvet off them.

"This is the Bunker Tree, also known as the Stupa Tree, which is a tree that grows on the coast. ”

Daonan explained to them one by one these rare plants. The eyes of the second child can't see it. The animals before were strange enough, and the plants were so unique and beautiful.

"This is the golden peach,"

Donan pointed to a beautiful species with bright green leaves, tall and golden yellow plants, spherical inflorescences, and clusters of flowers at the top of the branches.

"This flower is beautiful, take it back and raise a pot. ”

Degree said. It turned out that the boy also liked flowers.

"Why are there yellow clouds?"

Kai looked at the pile of yellow clouds in the distance, and Du saw it too. When you look closer, it looks like a golden pom-pom, and the small golden flower bulb is fluffy and very cute.

"It's so beautiful!"

Wuchai sighed, then let out a long sigh and turned back to look at the animals.

They remain naïve and innocent, unprepared against the newcomers to Homo sapiens. Homo sapiens look short and nothing particularly frightening, so they don't take them seriously.

However, their end has come. When Homo sapiens began to see these giant animals, he was terrified. After slowly looking at them, they realized that they were not fierce at all. So, they started to attack, targeting the giant animals first.

Until then, when Homo sapiens approached them, they looked at these humans stupidly, especially in the shadows, their eyes full of love.

Yes, they are defenseless against humans, and it will take a while for them to evolve before they become afraid of humans, however, there is no time left.

The cruelty and danger of the Homo sapiens, who have been living in anxiety and hunger, are infinitely magnified in this morning.

Similarly, the island's indigenous people, like the animals, did not escape extinction.

In this way, these cute animals were wiped out one by one by Homo sapiens. Until one day, a wise man came up with the problem that they were killing faster than the animals could reproduce, and if they continued like this, they themselves would lose food. He wanted to stop this predatory killing, but it was too late. The last big bird on Earth died, and from then on, the species became extinct.

In this way, twenty-three of the twenty-four large animal species here became extinct.

At this time, Wuchai's eyes were full of tears. There were times when she was about to rush down to stop their slaughter, but was stopped by Donan and Do.

"It's history, silly girl. ”

Daonan said with a smile. "Homo sapiens has stood at the top of the food chain as the deadliest biological species in the history of the planet. “

This is in the Americas, where there is a kind of mammoth with a furry appearance, which is very cute. There are fierce and terrifying saber-toothed tigers, mastodons, and rodents the size of elephant bears, giant ground sloths weighing up to eight tons and six meters high, giant lions, native horses and camels, all kinds of large mammals, reptiles and birds, as if you are in a peculiar zoo, and all kinds of animals and plants that have not been seen in the Asian and African continents breed here.

At this time, Homo sapiens are wantonly killing them. They killed the mammoth and carried it back, eating the mammoth's meat, absorbing the protein from the meat and saving the unfinished frozen food for the next meal. In addition to eating, there are also warm furs to keep warm, and precious ivory ornaments to wear on the body to show noble status.

At this time, the extinction of species across the globe is accelerating. In North America, 34 of the original 47 genera have become extinct, and only 10 of the 60 genera in South America remain. There are also thousands of small mammals, reptiles and birds, and even insects and parasites that are equally extinct. “

Daonan said solemnly that the entire history of human development is a heinous history of species extinction and the survival of Homo sapiens.

The second child sighed, but they could only watch.

Then the moon came out, and the tribesmen danced around a fire, and they danced strangely, and the steps were very simple, and they repeated these simple dances over and over again, tirelessly.

"They believe in ghosts and gods, and whenever the moon is full, they jump like this. They believed that the moon was a deity, and whenever the moon was full, the tribe would organize them to dance to worship the gods. ”

"They're going to die of exhaustion. ”

Du looked at them and said. Tao Nan said no, because the ancients were always running, racing with wild beasts, their tolerance was so strong that you can't believe it.
