Question
Evaluate the process of biogeography we see today in the distribution of mammals on the Australian and South American continents?(1 point)
Responses
Biogeography explains that animals on both continents travelled across the sea or sky to inhabit different continents and interbreed with the species already living there.
Biogeography explains that animals on both continents travelled across the sea or sky to inhabit different continents and interbreed with the species already living there.
Fossils on both continents are similar enough to conclude that both continents were once joined and animals travelled between them then evolved differently when the continents separated.

Biogeography explains how animals on both continents are so different that they have no physical or molecular features in common.

Fossils on both continents are so different that animal species evolved independently and happened to look similar despite the vast difference in location.

The most accurate response regarding the process of biogeography and the distribution of mammals on the Australian and South American continents is:
**Fossils on both continents are similar enough to conclude that both continents were once joined and animals travelled between them then evolved differently when the continents separated.**
This statement reflects the concept of continental drift and the idea of vicariance, where species that were once part of a larger population split due to geographical barriers and evolved independently in isolation. Both continents were part of the supercontinent Gondwana, and as they drifted apart, the mammals on each continent underwent divergent evolution, resulting in the distinct wildlife observed today.
