          It’s basically impossible to have a complete phylogenetic tree of bacteria and how they relate to eachother vs how they relate to common ancestors with the original eukaryotes let alone multicellular complex life. Prokaryotes as far as I know are seen as being a completely different branch more related to eachother than any eukaryotes so no, not really. Fish are a much more problematic group to exclude tetrapods from because bony fish like trouts, tuna etc are significantly more closely related to the tetrapods than either are to sharks and the other cartilagenous fish, all of which are more closely related to eachother than to the jawless fish like hagfish and lampreys.

          Tldr, if both trout and sharks are fish then monophyletically people also fall under the category of “jawed fish”

      Monophyletically they are, orcas (and people) are far more closely related to bony fish like trout than any of those are to sharks. If trout and shark are both fish then monophyletically so are we and orcas.
