New World Frogs
June 6, 2007 / Posted by: Shige Abe
A new paper on the evolutionary relationships among New World tropical frogs was published online this week in PNAS. The authors, including members of the NAI Penn State Team, used DNA sequence and molecular clock analyses to further understand the frogs’ origin as more likely by dispersal over water from South America, than via land connections with North and South America.
