Question

Two species might have similar skeletal structures that have different functions. What do these types of structures suggest about the relationship between the two species?

A. common sructures with different functions suggest that the species do not share a common ancestorcommon
B. sructures with different functions suggest that the species share a common ancestor that also have a similar
C. structurecommon sructures with different functions suggest that one of the species never learned how to use the structure properly
D. common sructures with different functions suggest that the species live in the same habitat

Answer 1

The answer is Common structures with different functions suggest that the species share a common ancestor that also had a similar structure I think. I just did the test lolz

Answer 2

b. Common structures with different functions suggest that the species share a common ancestor that also had a similar structure.

Step-by-step explanation:

The presence of organs with the same basic structures in the organisms of different species reflects their homology. It represents the fact these species shared a common ancestor that also had a similar structure. These homologous organs with identical basic structural plans have been used by the members of different species to perform different functions. For example, the bones of the forearms of humans and flippers of whales are the same. Humans use forearms mainly in holding objects while flippers assist whales in swimming.
