Get all parent taxonsI am trying to extract all the parent taxon (P171) definitions in wikidata. So the output I want is a long list of pairs of taxon (P225) and parent taxon IDs. The problem I'm having is that I don't get all the parent taxons, but just one (except for some cases!). In my output I only get Tetrapod (Q19159) as parent taxon for Mammal (Q7377) but there are 4 items in the database. The query I am using is:

Use at

• https://query.wikidata.org/sparql

PREFIX wdt: <http://www.wikidata.org/prop/direct/>
SELECT ?item ?parenttaxon WHERE {
  ?item wdt:P171 ?parenttaxon.
}
