To conquer Australia, you can catch rabbits and sharks on the ground. What animal is China?

When it comes to species invasion, everyone is familiar. With the closer contact between human beings, species have become very common all over the world with the footsteps of human beings, which is why modern species have invaded for so long. In the past, people's transportation technology was limited, and it was very difficult to go too far away, especially in some remote places.

Of all the continents in the world, Australia is the most isolated. There is only one country on this continent, and that is Australia. Due to long-term isolation, Australia's local ecosystem is also very strange. It is called the "World Museum of Living Fossils".

Australia has many unique species, including 654.38+200,000 plants and 9,000 species not found in other countries. There are 650 species of birds, 450 of which are endemic to Australia, and many unique ancient biological species preserved during the evolution of the earth. This has also created Australia's unique ecosystem, which is both stable and fragile.

Australia, which is vulnerable to species invasion, was conquered by China's "local dogs"

Australia's ecosystem has been relatively independent for a long time, and there are few exotic animals and plants, which also leads to a problem. Due to the influence of globalization, exotic species have entered Australia through different channels in recent decades, which often brings negative ecological impact to Australia. Even rabbits may become an invasive species in Australia.

China's "local dog" is an exception among many exotic species in Australia. I entered Australia very early and gradually adapted to the Australian environment. Now it's called "dingo". The dingo, a yellow native dog in Australia, looks no different from the native dog in China.

In fact, experts traced the genes of wild dogs in Australia and found that the ancestors of wild dogs in Australia can be traced back to a female dog 5,000 years ago, which is consistent with the time when Southeast Asian immigrants arrived in Australia by land bridge, so wild dogs in Australia and native dogs in China may really be the same species.

The Current Situation of China's "Native Dog" in Australia

This kind of dog came to Australia for a period of time and had a good life. Because there are no large carnivores in Australia and herbivores are not strong in their ability to escape, Australian wild dogs can mix like a duck to water and catch herbivores such as rabbits and sheep in the world. As a gregarious animal, Australian wild dogs can also catch sharks together in the water and are the top animals in the local biological chain.

However, due to the flooding of wild dogs in Australia, which were regarded as pests by local residents, local people began to expel and kill wild dogs in Australia. They spent millions of dollars to build and maintain a 5,290-kilometer fence to prevent wild dogs from approaching the sheep industry in southeastern Australia. People can also offer a reward for hunting Australian wild dogs. An Australian dingo can exchange 500 yuan dollars at most, which is equivalent to more than 3,000 RMB.

As a result of human hunting, wild dogs in Australia have become endangered animals. Scientists have also found that wild dogs in Australia don't eat sheep at all, and only choose sheep when food is scarce. Therefore, the Australian government protects wild dogs in national parks and reserves. Now they are Australia's second-class protected animals.
