Marsupials are found in North America and Australia, but they would not have been able to swim across the ocean. According to scientists, how did this group of organisms come to live on two separate continents?

Marsupials used to have adaptations that allowed them to swim but lost these adaptations over time.

The two groups of marsupials evolved independently of one another on two separate continents.

The continents were once connected, and marsupials were able to migrate over the land.

A scientist wrote a paper titled “Directional Selection in Action” after observing a population of mice for 15 years. The mice typically preferred to eat berries, although a few would also eat insects. After a drought in year 3, the scientist observed that more mice were eating insects.
