Answer:
this phenomenon is a natural consequence of evolutionary processes and continental drift
Explanation:
Marsupials are mammals in which newborn offspring are carried in a pouch of the female (mother) body. On the other hand, placentals are mammals that complete embryo development in the mother's body, in the placenta. All the extant marsupials are endemic to Australia and the Americas. It has been shown that marsupials diverged (evolved) in South America, Australia and Antarctica when these landmasses were joined. In Australia, marsupials evolved to fit an ecological niche, which can be attributed to geographic isolation due to continental drift, while placental mammals are relatively recent and more scarce (mainly bats and rodents) within this region.

It should be understood that the population growth rate of a particular country can be explained or described as the increase in the number of the citizens of that country.
There are so many factors that contribute to an increase in the number of people of a country. These include influx of people into the country, increase in birth rate and decrease in death or mortality rate.
In this case, the growth rate is usually calculated in percentage, so the growth rate should be around 3.5%.
