What has the same function but not the same evolutionary origin?

In evolutionary biology, analogous structures are defined as biological structures having similar or corresponding functions but not from the same evolutionary origin. In other words, species use these biological structures for the same purpose and yet these species are from unrelated evolutionary lines.

Homologous structures are similar structures that evolved from a common ancestor.

What are body parts of organisms that are similar in structure but not in function?

Solution : Homologous organs are similar in structure and origin but not necessarily in function. Hence, organs from different species having a similar basic form, microscopic strucutres, body position and embryonic development are said to be homologous.

Which are structures that have similar functions in two organisms that have not evolved from a common ancestral form?

Analogous structures are structures that are similar in unrelated organisms. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor. For example, the wings of bats and birds, shown in Figure below, look similar on the outside.
