A closer look at a classic ring species: The work of Tom Devitt

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.

Overview
Generalmente, pensamos en la especiación como un proceso lento. Toda la evidencia disponible sostiene la idea de que diferentes especies evolucionaron desde ancestros comunes, y sin embargo, nuevas especies no aparecen a nuestro alrededor diariamente. Para muchos biólogos, esto implica que la especiación ocurre tan lentamente que es difícil observarla en escalas de tiempo humanas. Sin embargo, nuevas investigaciones sugieren que la especiación podria ser más fácil de observar de lo que pensamos.

Overview
We often think of speciation as a slow process, so slow that we can't really observe it going on around us. This news brief from Febrary 2010 describes two examples which demonstrate that, at least occasionally, important steps toward speciation can be observed in less than 50 years.

Overview
Punctuated equilibrium is sometimes erroneously cited as evidence that evolutionary biology still hasn't figured out how evolution works. In fact nothing could be further from the truth. Punctuated equilibrium builds on (not tears down!) established evolutionary theory. Find out how the process works.
