Discussion

... that a subspecies of Black Lemur (pictured) is the only primate other than humans to have blue eyes? August 5, 2008 (although some recent taxonomoly updates may make this one outdated)

I think a source should go along with this one. If outdated, the article should specify the formal theory so that we can change this DYK to "... that a subspecies of Black Lemur was formerly the only primate other than humans to have blue eyes, but new studies indicate that... blah blah" or something similar. What do you think? Zoo Fari 21:41, 7 September 2009 (UTC)

The issue is that the recent Mittermeier, et al paper elevated the subspecies in question, Sclater's Lemur, to a separate species. And we have updated the Black Lemur and Sclater's Lemur articles according to that paper. So maybe just revise this to:

... that Sclater's Lemur (pictured) is the only primate other than humans to have blue eyes? August 5, 2008
