Just so you'll know.  There are actually now four published, differing, versions of the Zimmer article at the NY Times: l.  the original www.nytimes.com shorter article that went "viral" 2. the longer, illustrated version (including photos provided by Brian Boyd and Roger Vila) in print today at NY Times Science Times, which included historical context re: the work of Johnson, Balint and Benyamini, and also the DNA work of Chris Nice (published on the Karner Blue as a distinct species [again Nabokov was right!] in Dec. 2010). 3. an updated, but shorter than this latter in-print article, which is now posted at NY Times.com under Science. 4. that latter article corrected to include acknowledgment of Steve Coates. Kurt Johnson who living in NYC can monitor this stuff re: "what is where"
