Which of the following organisms evolved after amphibians?

Only cats
Only reptiles
Only marsupials and cats
Reptiles, marsupials, dogs, and cats

Answers

Answer:

Reptiles, marsupials, dogs, and cats

Explanation:

The correct answer is only reptiles as they evolved after amphibians.

Amphibians were one of the earliest groups of land-dwelling vertebrates to evolve. After amphibians, reptiles emerged. Reptiles are a diverse group of cold-blooded vertebrates that includes animals such as lizards, snakes, turtles, and crocodiles. They have adapted to a wide range of environments, including deserts, forests, and oceans.

The other options provided in the question, such as cats, marsupials, and dogs, did not evolve after amphibians. Cats and dogs belong to the mammal group, which evolved much later than amphibians. Marsupials, on the other hand, are a group of mammals that includes animals like kangaroos and koalas. While marsupials did evolve after amphibians, the question specifically asks for organisms that evolved "after amphibians," excluding any other groups that may have evolved concurrently.

So, the correct answer is "Only reptiles" because reptiles evolved after amphibians.
