Hurricanes twist evolution in island lizards
A new study from Washington University in St. Louis is the first to demonstrate evolutionary response to hurricanes on a wide geographic scale.
Biology study traces genes, shows lizard migration started in Florida
Researchers found that introduced populations of a lizard in five different countries can be traced back to the Sunshine State.
Mixing the ‘deck of genes’

Studying genetic variation in the common brown lizard, Anolis sagrei, the researchers found that introduced populations of the lizard in five different countries can be traced back to the Sunshine State as their site of export.
Researchers find a pattern in evolution of lizard groups
Courtesy photoBiologists at Washington University in St. Louis studying groups of lizards have proposed a general pattern among groups in the timing of evolutionary diversification.Many scientists believe that each group of living things evolves in its own idiosyncratic manner. But now biologists at Washington University in St. Louis have proposed a general pattern among groups in the timing of evolutionary diversification.
Biologists find unexpected rapid evolution in Caribbean lizards

The discovery is completely unexpected and challenges the way evolutionary biologists think of evolution.
