Tasmanian Tiger Did Not Fill the Evolutionary NIche of a Dog
It was believed that the Tasmanian Tiger perished in mainland Australia due to the dingo taking over their habitat. New findings show the dingo did not directly compete with the marsupial dog. They had different ways of getting their food.
Dingos were brought to Australia from Asia in recent times. It is not native to Australia. The demise of the Tasmanian tiger on the larger part of Australia 3,000 years ago was coincidental. Settlers in Tasmania feared their cattle and sheep would be slaughtered so they eradicated the quite timid animal in the early twentieth century.
Dingoes are wild dogs that run for long periods running down their prey. Tasmanian tigers were not distance runners. They ambushed sick and young animals. The tiger's skeletal structure was more like cats than dogs, particularly the elbow joint which was feline in character. The dingo has elbows that lock, while the marsupial dog had a flexible joint. This undermines the theory that the Tasmanian tiger filled the evolutionary niche open in Australia due to the absence of a native dog.

Vets Have Demanding Jobs and Don't Get Paid
People expect treatment of animals to be free. This is a fact. That is why there is a high suicide rate for veterinary surgeons. The suicide rate for vets is four times higher than the rest of the population.
In cities people take their pets to the vet when there is serious injury or illness or when an animal is at death's door. If their pet dies while being treated or operated on it is the norm, expected, that the vet will wave charges. And again, after a pet is put down it is deemed to be rude for the vet to charge a reasonable fee.
Rural regions operate in a different way. Veterinary surgeons are on duty 24 hours a day, 7 days a week. At lambing time they are rushed off their feet. Every farmer pays 3 months after service, so vets are in debt to the bank from the start. The days of paying with eggs are not gone either. Meat is often offered as payment.
Why do people train to be vets? They obviously love animals, like the technical side of the job, or have community spirit. They will not become wealthy nor have secure futures.
