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.

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.”

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.
