imageIsland biogeography and evolution: Solving a phylogenetic puzzle using molecular genetics
Students focus on the evolution of three species of lizards using real data sets – geographical and geological data, then morphology, and finally molecular data – to determine possible phylogenetic explanations.

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

imageParsimonious explanations for punctuated patterns
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.
