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.

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.”

As a quantum state collapses, it will follow a path known as a quantum trajectory. In a new paper featured this week on the cover of Nature, scientists have shown that it is possible to track these quantum trajectories and compare them to a theory, recently developed by University of Rochester physicists, for predicting the most likely path a system will take.
