DNA Decoded by FSU Biologist Reveals Seven New Mice Species
International Team’s Discovery in Philippines Showcases Biodiversity, Evolutionary Wonders
TALLAHASSEE, Fla. –– After living incognito for millions of years in a remote area of a forested mountain range in the Philippines, seven newfound species of mice owe their recent discovery to DNA evidence and the Florida State University biologist who deciphered it.
What’s more, the DNA drawn from the reclusive “new” mammals told FSU Associate Professor Scott J. Steppan an unusual evolutionary story. As he analyzed and compared the genetic codes of mice found in separate but proximate parts of a small area on Luzon, the largest Philippine island, he determined that while each mouse was a distinct species, they all belonged to the forest-mouse genus Apomys. That meant all seven mice were both “new” and closely related to one another.
“It is extraordinary, really almost unprecedented, to have so many closely related mammal species from such a small area that forms just one-half of one island –– let alone to have discovered so many so quickly,” said Steppan, whose laboratory at Florida State coordinates the DNA sequencing portion of an ongoing biodiversity project led by Chicago’s Field Museum of Natural History.
