Molecular phylogenies have provided strong evidence for clarifying the taxonomy of groups with ambiguous morphological traits, thus avoiding potentially misleading conclusions based on evolutionary convergence of these traits. Leer más.
Virginia is home to three species of venomous snakes: timber rattlesnakes, cottonmouths, and copperheads. Copperheads (Agkistodon contortrix) are the least venomous of the three and are present in the south east quarter of the United States, excluding most of Florida and parts of Texas and Georgia.

Through the careful study of modern and early fossil tortoise, researchers now have a better understanding of how tortoises breathe and the evolutionary processes that helped shape their unique breathing apparatus and tortoise shell. Leer más.
A study by researchers in Sweden and Spain says that global warming is altering the reproduction of plants and animals, notably accelerating the date when reproduction and other life processes occur. They found that some amphibians are capable of making their offspring grow at a faster rate if they have been born later due to the climate. Leer más.
