Which structures are similar in function, but do not indicate that the organisms are related?

What is the value of a transitional fossil?

Siblings have similar traits because they inherit those traits from a common ancestor. How is this similar to some evidence for evolution?

Biology shows us the fossil record and comparative anatomies. Chemistry shows us that organic molecules can come from inorganic matter. Geology shows us that organisms that used to live together are found on separate continents due to continental drift. Which fields of science provide evidence for evolution?

Studying the anatomy of different organisms allows scientists to determine how different species have evolved over time. Which type of anatomic structure are bird wings and butterfly wings when compared to each other?

Which lists the correct order of evolutionary history?

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?
