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?
A) Marsupials used to have adaptations that allowed them to swim but lost these adaptations over time.
B) The two groups of marsupials evolved independently of one another on two separate continents.
C) The continents were once connected, and marsupials were able to migrate over the land.
D) The oceans were shallow in prehistoric times, which allowed the marsupials to travel from one continent to another.
Answer:
C) The continents were once corrected and Marsupials are able to migrate over the land.
Explanation:
Marsupials are a group of animals which can give birth to young ones at an early stage and keep them in a pouch until they mature therefore also known as pouched mammals.
The evolutionary studies have shown that marsupials originated on a single landmass called Gondwana which separated into different continents. The marsupials used to live in the Gondwana land but after separation of land, the ancestors of marsupials separated and the marsupials evolved on the landmass of South America and Australia.
Thus, Option-C is the correct answer.
Answer: Modern technology can analyze, compare, and save more information than our brains can. Genes and proteins are small, but 3D modeling on computers can help build it to a scale that we can see. Information can be saved and stored for later use, and it's easier to access when it's all on one operating system.
