The man-rabbit wars lasted 150 years and Australia was defeated. How could 10 billion rabbits possibly eat all of them?
“Rabbit rabbit so lovely, how can you kill rabbit rabbit?”If you say that to an Australian, they go ballistic!In Australia, bunnies are not cute creatures at all. They are downright evil, damaging the environment and harming people.The “man-rabbit war” between Australians and rabbits has been going on for 150 years.As a result, not only did rabbits not decrease, they far outnumbered the population of Australia!Australia totally defeated!We often see such news in Australia’s newbie village, such as kangaroos beating people, camels flooding Australia, wild cats flooding Australia requiring artificial hunting, etc., as well as A series of weird things like Australians beating emus in Europe during World War I.People can’t help but wonder, in other continents, animals are struggling to survive, but in Australia, the situation is reversed.Is this how people get bullied by animals?This brings us to Australia’s unique ecological structure. It is a lonely continent with no contiguous landmass. The nearest continent to it is Antarctica.It was originally part of gondwana, an ancient land in the south, as tectonic plates drifted away.Most of the animals on the Continent were there before they drifted, and because of the age, an ancient group of mammals was left behind: the metatheria, or marsupials.The southern ancient continent of Gondwana Australia is known as the paradise of marsupials. Before the arrival of human footprints, the entire continent was almost devoid of eutheria, the subclass we call placentas.These mammals and mammals cannot be generalized, and although they are generally the more advanced group of vertebrates, metatheria is evolutionarily more backward in body structure than Eutheria.Metatheria’s evolution was limited by the need to raise their young in pouches, which meant they had to hold on to their mothers and were unable to free their forelimbs.Eutheria, on the other hand, developed in the mother’s belly and was born at a certain point without holding onto the pouch, which allowed the arms to leap forward and evolve into primate hands, chiropteran wings, and even subwhale fins.The evolution of the “parenting” kangaroo animals has always been one step behind is backward, the beast subclass the limitations of this nature make it can’t be in the later competition more than true beast subclass, they quickly retreat in ancient continent, finally retreat to the corner of the gondwana continent, as continental drift they leave, with the Australian mainland just before that do not have true beast subclass to enter,So this is the last frontier for metatherians.Most of the metazoans that remained on other continents, with the exception of small animals like possums, were wiped out by later competition.Aborigines landed on the isolated island about 40,000 years ago, and a group of Southeast Asian settlers arrived about 5,000 years ago, bringing their dogs with them.Then the man left, but the dog stayed.These dogs are one of the most important animals in Australia because there are no large carnivores on the continent and the early ancient monitor lizards were wiped out by aborigines.So these dogs soon became Australia’s top predator, the Dingo.About 200 years ago, When European settlers arrived, they brought with them a range of animals, such as cats, rabbits and mice.The arrival of these more advanced eutherians in Australia was like the arrival of the grand masters in the novice village, and they quickly broke down the framework established by the metatherians in Australia.The rabbit is a general term for the rabbit family of the order Lacriformes. In earlier years, the molecular biology was underdeveloped and rabbits were considered to be rodents.Therefore, there are certain similarities between a rabbit and a mouse. The first is its two big front teeth, which can grow for a lifetime. Even in old age, a rabbit can stay in good health and eat well.Rabbits are second only to rats in terms of reproductive capacity, with rats having 12 births a year at their highest, and rabbits giving birth six times a year.Rabbit structure Rabbits are much larger than mice, and to increase their fertility, they have evolved a double uterus, in which a mother can give birth to one litter and carry another.This rate of reproduction has also spread rabbits to lands beyond Australia and Antarctica.It also naturally became part of the human diet.So since Australia has no native rabbits, how did it get its 10 billion rabbits?Of course they were brought by people.When the age of navigation began, European ships sailed one after another around the world, and Australia was discovered at the same time as America.European colonists, of course, did not let go of the rich continent, so they went in large numbers.Because of the long distance, they carry rabbits as a source of meat.Delicious rabbit meat because rabbits are so adaptable, they can be brought on boats and reared in captivity in Australia.In the beginning, rabbits were the precious property of the colonists and could not be released easily. As more and more colonists came to the colony, the animals they raised became larger. Large livestock such as cows, sheep and pigs replaced rabbits, and rabbits became the pets of the colonists.In 1859, Englishman Thomas Austin brought 12 grey rabbits, five hares, 72 partridges and a few sparrows from England for fun.He kept the animals on his own estate for his own pleasure.Soon other Settlers in Australia followed suit, and large numbers of rabbits were introduced as hunting targets, and management became increasingly lax, eventually causing large numbers of rabbits to escape into the wild.Australia was overrun with rabbits. Australia was large and sparsely populated, and rabbits were very adaptable and resilient, and soon their numbers began to grow exponentially.By the time people in Australia realized something was wrong, the rabbit population had exceeded 10 million.At that time, Australia mainly developed agriculture and animal husbandry, and rabbits were the number one natural enemy of people. In order to pick up rabbits, people made mistakes in their busy work and chose to introduce red foxes, which were not found in the Australian mainland. As a result, after foxes came to Australia, they found that catching rabbits was better than catching other marsupials, who made them run so slowly?As a result, one wave has not been leveled yet, the rabbit side has not been solved, and the fox has become a scourge.The Australians regretted that they had started the match manually.Since 1887, Australia has encouraged people to take part in the hunt for rabbits, offering a $3 million prize.Under such a stimulus, the Australians did kill rabbits intrepid, but not fast enough to keep up with the rate of reproduction.Soon the rabbit population topped 100 million, 1 billion, and eventually more than 10 billion, and in a country of just over 20 million people, every man, woman, and child had to kill 500 rabbits per person, and that’s not taking into account the number of rabbits produced.Rabbit Hunting By this method of brute force killing, the Australians were defeated.The Rabbit of Australia is a cross between many species of rabbit and is biologically loosely classified as the Australian hare.But no matter how hybrid, these belong to the rabbitformes rabbit family members, so Ming play, however, Australians play Yin.Instead of introducing a rabbit’s natural enemy, they introduced a virus specifically designed to neutralize rabbits.Australian biologists traveled to many rabbit breeding countries and picked up myxomatosis virus, a virus that only spreads between rabbits.When rabbits are infected with the virus, their anus and genitals become swollen, ulcerated and swollen, and they die.I have to say this is a very bad move, but then I think, if we don’t curb the rabbit population, the ecology of Australia will be destroyed, and the native animals will be seriously affected.Australia is the only continent to retain a large number of metatheria genes, ancient mammals that are anatomically backward but are the subject of living fossil studies.Through them, we can see the survival of mammals in prehistoric times.Australian hares are descended from colonist rabbits and are of little scientific interest in their own right. In the face of precious metazoans, it is best to leave the world at once.Why don’t australians eat these rabbits like the Chinese, one might ask?First of all, there are 500 times as many rabbits in Australia as there are people. How could they possibly eat all of them?Secondly, Australians are not very fond of rabbit, as they still prefer red meat.Finally, Australia used the virus to exterminate rabbits, which are best left uneaten.A pile of rabbit skins, taken in New South Wales. This is a very damaging way of deterrence, but the number of rabbits is so large that, in the end, it’s very likely that there will be super-resistant rabbits.So in addition to myxomatosis, biologists have to look for new viruses.Australia’s man-rabbit wars continue.
