In the last hundred years, species have become extinct 1,000 times faster than nature through human intervention. Seventy-five species go extinct every day and 3 species every hour worldwide. Many species have disappeared from the earth forever due to changes in the environment before they have been discovered or named.

The number of extinct animals that are old is even more numerous. The more famous ones are giant otters, short-faced bears, cave bears, saber-toothed tigers, North Asian giant tigers, eagle-toothed beasts, long-haired rhinoceros, dinosaurs, titan pythons, Irish elk, cougars, marsupial lions and cave lions, as well as dinosaur families known to women and children.

The giant ground otter, also known as the earth otter, became extinct 8,000 years ago. The giant animal stands six meters tall and is estimated to weigh four tons, equivalent to the weight of an African elephant.

In some dry caves in North America, scientists have found giant otter mummified skin and some hair, which is the best source of DNA, and it is feasible to resurrect them.

But giant ground sloths are so large that the genetically similar sloths are only 4 to 7 kilograms, a difference of hundreds of times in size.

Extinct 7,700 years ago, the Irish moose looks more like a deer in shape, but is two meters tall and has horns up to 4 meters wide, making it the largest known deer species.

The current living close relative is the European pale yellow deer, but the light yellow deer is much smaller.

Both the woolly rhino and the saber-toothed tiger went extinct about 10,000 years ago.

The woolly rhinoceros, also known as the woolly rhinoceros, lives in northern Eurasia. It has a thick layer of fur and subcutaneous fat to keep warm in cold environments. The woolly rhinoceros was hunted by early humans, possibly contributing to its extinction.

Like a mammoth. There are also many samples of woolly rhinoceros hidden in permafrost. Including hair, horns, hooves, etc. After cleaning these tissues, there will be a large amount of near-pure DNA, and it will not be difficult to revive the woolly rhinoceros.

The problem is that there are many rhinos of the same era as the woolly rhinoceros that are currently on the verge of extinction, and it is more important to protect these rhinos than to resurrect them.

The saber-toothed tiger was about the same size as the modern tiger, but the upper canine teeth were much larger than the modern tiger, and even larger than the fangs of a wild boar, like two sharp daggers. This is where its name comes from.

A well-preserved sample of a saber-toothed tiger has been excavated in an asphalt pit in downtown Los Angeles, and once the intact DNA is extracted, the African lion will be an ideal "surrogate" for the saber-toothed tiger.

Short-faced bears lived on the North American continent 2 million years ago and are fearsome carnivores. Their main prey is the bull and the buffalo, which is why they are also known as the "bull bears".

When walking, the back of the short-faced bear is about 1.5 meters above the ground, and when it is upright, it is more than 3.4 meters. The polar bear, the world's largest carnivore, is only one-third the size of it.

However, short-faced bears have long limbs. But it is more "slim", and its weight is not as heavy as people think. Paleozoologists estimate that it is only about 700 kilograms, which is only a few dozen kilograms heavier than the largest polar bear.

At present, there are specimens of short-faced bears preserved in the frozen soil, but it is difficult to find "surrogate mothers" for short-faced bears, and the only South American spectacled bear genetically similar to short-faced bears is only one-tenth of the size of short-faced bears, and it is difficult to undertake the work of "surrogate mothers".

Whether extinct ancient animals can be reproduced in humans depends not only on the preservation of samples, but also on the ability to find genetically similar modern relatives, and viviparous animals also need "surrogate mothers" with suitable body sizes.

Many ancient creatures only have fossils, not even modern relatives, and it is difficult to achieve resurrection, perhaps only when biotechnology becomes more advanced in the future.

……

What Ye Quan wanted to resurrect most in his heart was actually the white-sided dolphin and the dinosaur.

The white-sided dolphin is beautiful, ancient and rare, living in the Yangtze River for about 25 million years, is an ancient relict species that has survived in the Miocene and Pliocene, and is a precious "living fossil" for the study of cetacean evolution, and it has important scientific research value for biomimicry, physiology, zoology and military science.

In the ancient book "Erya" more than 2,000 years ago, there is also a description of the white-sided dolphin, which is regarded as the god of the river and the spirit in the water.

The white-sided dolphin is a small individual member of the cetacean family and is one of the five species of freshwater dolphins in the world. The white-sided dolphin likes to live in groups, reproduces once every two years, has 1 litter per litter, and is about 80 cm long at birth.

The white-sided dolphin was widely stored in the Dongting Lake and Poyang Lake area of the Yangtze River basin, and in the new century, people have been difficult to find the fang, the relevant departments and scientists, several large-scale search operations have been unsuccessful, and the last white-sided dolphin in captivity "Qiqi" also died as early as July 2002.

After the failure of the joint large-scale search operation of cetacean scientists from various countries in 06, foreign media reported: "The white-sided dolphin of the Changhe River of Xinhua has become extinct!" ”

Only some domestic experts have been hard-mouthed and have refused to lift the fig leaf, but there is no evidence that there are still living white-sided dolphins in the Yangtze River basin.

However, white-sided dolphins are aquatic creatures, and the technical difficulty of implanting embryos in the womb is incomparable to that of terrestrial animals.

The resurrection of dinosaurs is even more difficult, from the current biological theory, dinosaurs are impossible to resurrect, because after more than 60 million years, the genes of dinosaurs are almost all decomposed.

As described in the movie "Jurassic Park", it is impossible to clone a dinosaur with the dinosaur blood sucked by the prehistoric mosquito in amber, because even if it is really a drop of dinosaur blood, it is impossible to preserve complete and pure genes after tens of millions of years after the mosquito gastric juice digestion, decay, decomposition, high temperature and pressure when amber is formed, let alone patched with frog genes, some small dinosaurs eventually evolved into birds, not frogs.

Although the biological chamber has this technical foundation, it is impossible to do things in one step, and Ye Quan finally decided to resurrect the dodo, which became extinct in 1690.

The dodo is one of the most famous extinct animals outside of dinosaurs.

And also to compete with the Dragon Eagle Group, the dodo and the pigeon are close relatives, the incubation period is very short, only about 18 days.

In addition, the dodo has a unique and cute appearance, feeds on various fruits, has no attack power, and is easy to get close to people, which is also one of the reasons why Ye Quan chose it.

When the technology in all aspects is mature, we will gradually resurrect dinosaurs and other ancient prehistoric creatures.

The dodo, also known as the dodo, or the Mauritian dodo, dove, lone pigeon, etc., is a flightless bird that is only found on the island of Mauritius in the Indian Ocean.

After being discovered by humans, this bird became completely extinct in just 82 years due to human hunting and human activities.

The famous "Oxford Dodo" is the world's best-preserved specimen of the Degree Bird, with a head and a sole of foot, as well as remnants of soft tissue.

By looking through the soft tissues of the guò dodo, the complete genome can be revealed, which in turn can resurrect this large bird.

On the eighth day of the Dragon Eagle Group's announcement that it would resurrect the mammoth, Taoyuan Group also held a press conference, announcing that the group's biological real room cooperated with the Oxford University Museum of Natural History to use cloning technology to successfully implant the dodo's gene in the meat pigeon egg, and if the progress goes smoothly, the dodo will be successfully resurrected within two months.

One stone has stirred up a thousand waves, and at present, the biological field of various countries has only made achievements in cloning mammals. To date, no one has succeeded in cloning birds, reptiles, or aquatic animals.

If Longying Group is one of the leaders in the biological industry, then Taoyuan Group is a rising star, although it is a newly established company, but it has already been famous in various countries, but the group previously focused on plant research and improvement.

In just half a year, Taoyuan Group has launched super upland rice 41, Taoyuan regenerative rice 19, Evergreen Forage No. 1, No. 7 and other crops with great influence; There are also new types of water hyacinths and devouring vines for environmental management; and improved mosquito repellent grass, flytrap, pitcher plant, bottle grass and sundew.

There is even a new tree species called the "World Tree", which grows at a rate that is so fast that botanists now guard the tree and measure its height every day, and it turns out that the World Tree grows one meter taller every three days!

After this news was announced, it immediately shocked the world! It attracts countless people to watch, and it is impossible to imagine that it only takes a few years for a tree to grow hundreds of meters high!

The group flower tree that grows in Yunxi Province, Nanling Province and Southeast Asia in Xinhua Province can grow up to 3.5 meters tall in a year, and is known as the "miracle tree". Balsa wood, which grows in Central and South America, grows faster than the flowering tree, growing up to 5 meters tall in a year.

But these two "miracle trees" are weaker than the World Tree.

This news from Taoyuan Group naturally attracted a lot of skepticism, thinking that it was too difficult to resurrect birds, and judging from the current top genetic cloning technology in various countries, it could not reach that kind of process.

However, Taoyuan Group is a large enterprise with strong technical force, and it is impossible to joke about its reputation, and two months is not a long time, and the truth will be revealed after a while.

Anyway, with the announcement of Taoyuan Group, the world is much more lively. (To be continued......)
