- 9-12
- 13-16
- General
Source:

Overview
The Ensatina salamander has been extensively investigated because it is a ring species — a species that demonstrates how geography and the gradual accumulation of genetic differences factor into the process of speciation. Biologist Tom Devitt continues the more than 50 years of Ensatina research by applying new genetic techniques and asking new questions about this classic evolutionary example.
