Editing Philippine eagle (section)

===Evolutionary history===
A 1919 study of the bird's skeletal features led to the suggestion that the nearest relative was the [[Harpy eagle]] (''Harpia harpyja'').<ref>{{cite journal| author=Shufeldt, RW|title=Osteological and other notes on the monkey-eating eagle of the Philippines, ''Pithecophaga jefferyi'' Grant|journal=Philippine Journal of Science|volume=15|pages=31–58|year=1919|url=https://archive.org/stream/philippinejourna15maniuoft#page/31/mode/1up}}</ref> The species was included in the subfamily [[Harpiinae]] until a 2005 study of [[DNA]] sequences which identified them as not members of the group, finding instead that the nearest relatives are [[Snake eagle]]s (Circaetinae), such as the [[bateleur]]. The species has subsequently been placed in the subfamily Circaetinae.<ref>{{cite journal|title=Phylogeny of eagles, Old World vultures, and other Accipitridae based on nuclear and mitochondrial DNA|last1=Lerner |first1= Heather R.L.  |first2=David P. |last2=Mindell | journal=Molecular Phylogenetics and Evolution|volume=37 |year=2005|pages=327–46| doi=10.1016/j.ympev.2005.04.010|url=http://www-personal.umich.edu/~hlerner/LM2005.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www-personal.umich.edu/~hlerner/LM2005.pdf |archive-date=2022-10-09 |url-status=live|pmid=15925523|issue=2|bibcode=2005MolPE..37..327L }}</ref>
