Question

To control its wild rabbit population, the Australian government introduced the viral disease myxomatosis. At first the virus was very deadly to the rabbits, but over the years, the virus became less deadly. Explain what might have happened to the rabbit population and why the virus became less dead

Answer 1

Natural Selection

Step-by-step explanation:

Overtime the the animals that had a natural immunity to the disease bred and produced offspring that also had this immunity, while the other animals that didn't dies off. So the population would have become smaller, but only for a little bit. Overtime this immunity will become more common in the population.
