How did the thylacine become extinct?
The thylacine is a carnivore that originally lived in Australia, and the female will also have a nursery bag on her abdomen, and after their cubs are born, they will live in the nursery bag for 2 to 3 months before re-entering the world; Although there is a word "wolf" in the name of the thylacine, they are not in the same family as the wolf, but they look more like wolves and also have a nursery bag, which is why people are given such a name. However, the thylacine is already an extinct animal, so how did they become extinct?
Thylacines arose about 4 million years ago, they are relatively small, fast, and have relatively good predation skills, generally ambushing, coupled with better endurance, and they also have their place among Australian carnivores. Before people arrived in Australia, the thylacine had adapted to the local environment, and animals such as dipterodonts and taupeums had formed a mutually restrictive relationship to maintain ecological balance.
But then with the arrival of the colonizers, this balance was gradually broken. In fact, at that time, people did not have very efficient hunting tools, but there was a secret weapon that most beasts of prey were very afraid of, and this secret weapon was fire. Colonists used fire to reclaim wasteland to open up their own new homes, burning a lot of plants and burning the homes of many animals.
Influenced by these factors, larger carnivores such as taupers, ancient monitor lizards and dipterodonts quickly went extinct due to their inability to adapt to the rapid changes in the environment. By losing the constraints of large carnivores, the population of thylacines can develop rapidly. Although the thylacine will also prey on some livestock, which has a certain contradiction with the colonizers, the thylacine has a wider range of activities, and even if it is hunted by the early colonists, it will not affect their number too much, so the early colonists play a role in promoting the number of thylacines.
But this effect soon turned negative, as colonists came to the land and brought dogs to the land, and in the beginning, dogs did not threaten the thylacine's living space. However, as the number of dogs increased, some dogs also began to break free of their owners and become wild dogs.
These dogs will have a certain wild nature after becoming wild dogs, but because they have been tamed by humans, their range of activities will not be too far away from people's range. However, these wild dogs need food, so they have to target their prey on human-raised livestock, and many village livestock have been attacked.
But in the eyes of these colonists, they have always believed that dogs are human friends and basically will not do such things, so the responsibility for the attack on their domestic animals falls on the thylacine. At this time, people began to take large-scale revenge on thylacines, and they burned their habitats by a large margin, and at the same time, there were retaliatory killings, which made the number of thylacines decrease rapidly.
Later, in the Australian land, the thylacine has almost disappeared, leaving only the island of Stamaniya still has a certain number of thylacines, due to the strait barrier at that time, wild dogs can not land on the island, and people rarely set foot in this area, which also makes the thylacine still have a space to live. But then the colonists landed on Theamania Island, and also brought dogs to the island, gradually making the thylacines on the island also repeat the fate of the Australian thylacine, and slowly went extinct.
The extinction of the thylacine undoubtedly has a lot to do with the disorderly expansion of the colonizers, and it is precisely because of people's ignorance and prejudice that the extinction of this species is caused. What do you think? #Thylacine # #Extinction#
