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. the oceans were shallow in prehistoric times, which allowed the marsupials to travel from one continent to another.
Answer
Brief Explanations:
The theory of continental drift suggests that continents were once joined. Marsupials could have migrated over land when the continents were connected and then became separated as the continents drifted apart. There is no evidence marsupials had swimming - related adaptations that they lost, and it is highly unlikely they evolved independently on two separate continents given their similarities. Also, there is no strong evidence that oceans were shallow enough for them to travel across.
Answer:
The continents were once connected, and marsupials were able to migrate over the land.
