Geologists found fossils of similar marsupials from the same time period across South America, Africa, Antarctica, India and Australia. What theory is supported by this discovery.

Question

Early marsupials were strong swimmers.
Those continents were once part of one supercontinent.
A vast land bridge once connected those continents.
The processes happening today are the same processes that have occured in the past.

Answer 1

The discovery of fossils of similar marsupials from the same time period across South America, Africa, Antarctica, India, and Australia supports the theory that those continents were once part of one supercontinent. This is consistent with the theory of continental drift, which suggests that these landmasses were once connected as part of a larger landmass, often referred to as Gondwana. Over time, geological processes caused the continents to drift apart, which would explain the distribution of similar fossils across these now-separated regions.
