These are physical features shared by organisms with common ancestry; they may have the same structure What are these shared physical features?

Homologous structures

Explanation:

Homologous structures are the physical features that are derived from a common ancestor. They can be superficially different but they are related to each other developmentally. Homologous structures do not mean that these structures will perform the same function.

Some of the examples of homologous structures are forelimbs of humans, frogs, bat. These structures perform different functions in different organisms because they got different environments and conditions to survive. Therefore the correct answer is homologous structures.

allowed for the prediction of the properties of missing elements.
