Question

the organs which are structurally different and founctionlly similar

Answer 1

Analogous organs are which have similar functions but different origins. An example of an analogous trait would be the wings of insects, bats and birds that evolved independently in each lineage separately after diverging from an ancestor without wings.

Answer 2

Organs that have the same internal structure but perform different functions are called homologous organs. The presence of homologous organs in different organisms indicates that they have evolved from a common ancestor.
