			Ghosts of epidemics past - October 2008 Diseases that pose global health threats — like HIV, malaria, and tuberculosis — regularly make the news. Last month, for example, saw reports that HIV infection rates in the US are up, that malaria statistics worldwide are down, and that the distribution of medicines to treat the three diseases had improved. Diseases with such epidemic proportions tend to make us focus on the near future: Regardless of how we wound up in this situation, what can we do now to prevent future infections and deaths?

How to survive a mass extinction: The work of David Jablonski David Jablonski researches how patterns of evolution relate to mass extinctions. Why are some species doomed while others survive?				Phylogenetic systematics, a.k.a. evolutionary trees All life on Earth is united by evolutionary history; we are all evolutionary cousins — twigs on the tree of life. Phylogenetic systematics is the formal name for the field within biology that reconstructs evolutionary history and studies the patterns of relationships among organisms.
Using trees to understand plants: The work of Chelsea Specht This research profile examines how the scientist Chelsea Specht studies plant evolution in order to understand the basis of diversity.				DNA and mutations Mutations are the ultimate source of genetic variation and are therefore, essential to evolution. Learn more about the causes, effects, and types of mutations, as well as their role in evolution.
