New prehistoric bird species discovered

December 16, 2016

A team of Rochester geologists has discovered a new species of bird in the Canadian Arctic. At approximately 90 million years old, the bird fossils are among the oldest avian records found in the northernmost latitude.

‘Selfish’ DNA flouts rules of inheritance

February 24, 2016

If researchers aren’t careful, they may be hoodwinked into thinking that a selfish gene is one that has some evolutionary advantage, says Daven Presgraves, an evolutionary geneticist at the University of Rochester.

Can cities change Earth’s evolution?

March 3, 2015

But what if evolutionary change could operate much faster? What if evolution could dance to the same beat as something like ecology — the interaction of life with changing environments? (by professor of astrophysics Adam Frank)

Alternate mechanism of species formation picks up support, thanks to a South American ant

Alternate mechanism of species formation picks up support, thanks to a South American ant

August 22, 2014

Pictured at left is the queen ant of the parasitic species Mycocepurus castrator. This ant, only found in a single patch of eucalyptus trees on the São Paulo State University campus in Brazil, branched off from its original species while living in the same colony, something thought rare in current models of evolutionary development.

Alternate mechanism of species formation picks up support, thanks to a South American ant

August 21, 2014

A newly-discovered species of ant supports a controversial theory of species formation. “Most new species come about in geographic isolation,” said Christian Rabeling, assistant professor of biology at the University of Rochester. “We now have evidence that speciation can take place within a single colony.”

Madagascar No Longer an Evolutionary Hotspot

Madagascar No Longer an Evolutionary Hotspot

July 10, 2013

Daniel Scantlebury calls Madagascar “an ideal evolutionary laboratory” for studying species formation because it has long been isolated and geologically stable relative to other regions.
