Field Museum Scientists Use DNA to Unlock Extinction Mystery of Xerces Blue Butterfly


Was the elegy misguided?
The Xerces status as a distinct species, as opposed to being a sub-population of another non-extinct butterfly, has been questioned by some for decades.
In a new study published in Biology Letters, researchers at the Field Museum were able to put a definitive end to those doubts, confirming that the Xerces blue was indeed a unique species, albeit one now also confirmed as extinct.
“It’s interesting to reaffirm that what people have been thinking for nearly 100 years is true, that this was a species driven to extinction by human activities,” said Felix Grewe, co-director of the Field’s Grainger Bioinformatics Center and the lead author of the Biology Letters paper on the project. ....
