			HIV's not-so-ancient history - November 2008 Ancient Egyptians described diabetes on a scrap of papyrus 3500 years ago. Two thousand four hundred years ago, Parkinson's was first outlined in a Chinese medical text. And Chinese, Greek, Roman, and Indian civilizations had all recognized malaria long before we had microscopes to observe the parasites that cause the disease. By comparison, HIV is a distinctly modern disease. It was first described in 1981, and drugs to treat it weren't available until 1987. But for how long before its discovery did HIV lurk unnoticed in human populations? Read the whole story to see the evolution connection. >> BONUS: This month's news item includes a video podcast!

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?				Why the eye? Eyes are clearly incredibly useful, but where did the eye come from? How did so many animals evolve eyes and why do they look so different? This case study answers these questions.
The genes that lie beneath: The work of Leslea Hlusko This research profile examines how the scientist Leslea Hlusko studies modern baboons to achieve a better understanding of ancient hominid evolution.				Biological warfare and the coevolutionary arms race Dr. Edmund D. Brodie, Jr. explores the ten-thousand year evolutionary battle between toxic newts and the snakes who dine on them.
