    The separation between vertebrates and invertebrates is so ancient it predates the development of any organ.

    Analogous structures reefers to similar structures that do similar things which evolved independently.

    For example a dolphin fin and a fish fin are analogous, even though they evolved completely independently.

    An insect anus, would be analogous to ours, even though evolutionarily speaking Our mouth is their anus:

    I think you’re thinking of homologous structures. Like a bird wing/human arm/horse front limb/dolphin fin are all homologous but have very distinct functions. Which would not apply between vertebrates and invertebrates given we diverged when we were a bunch of cells. (there’s still homologies, but mostly on the cellular/subcellular level).

    Bees and ant are absolutely amazing creatures, we just discovered an ant species that can clone another species.
