Fish and amoebae are likely to evolve from the same ancestor. Both fish and amoebae are classified as eukaryotes, meaning they have a nucleus in their cells. This suggests that they shared a common ancestor in the evolutionary tree of life. Fungi, while also eukaryotic, are not as closely related to fish and amoebae as they are to each other. Birds, on the other hand, are in a completely different evolutionary lineage from fish and amoebae, as they are part of the animal kingdom.
