Evo in the news: Livestock kick a drug habit
This news brief, from September of 2005, describes the FDA ban on the use of the antibiotic Baytril in poultry production. The decision was made in order to reduce the danger presented by the evolution of antibiotic resistant bacteria.

Evo in the news: Seeing the tree for the twigs
Recent research has revealed that, in at least some ways, chimpanzees have evolved more than humans have. This news brief from May 2007 delves into this finding further and, in the process, debunks common misperceptions of human evolution.

Evo in the news: Got lactase?
The ability to digest milk is a recent evolutionary innovation that has spread through some human populations. This news brief from April 2007 describes how evolution has allowed different human populations to take advantage of the nutritional possibilities of dairying and links evolution with the prevalence of lactose tolerance among people of different ethnicities.

Evo in the news: A chink in HIV's evolutionary armor
Medical researchers have spent billions of dollars and many decades trying to develop an HIV vaccine but have, thus far, failed. Why is an HIV vaccine so elusive? This news brief from March 2007 explains how HIV's rapid rate of evolution challenges medicine and describes a new discovery that may allow vaccine developers to sidestep that evolution.

A look at linguistic evolution
We typically think of evolution occurring within populations of organisms. But in fact, evolutionary concepts can be applied even beyond the biological world. Any system that has variation, differential reproduction, and some form of inheritance will evolve if given enough time. Find out how an understanding of evolution can illuminate the field of linguistics.

The Making of the Fittest: The Birth and Death of Genes
This 13-minute film describes how scientists have pieced together the evolutionary history of the Antarctic icefish by studying its genome – an excellent case study for genetic evolution as both the gain and loss of genes have led to key adaptations.

Mechanisms of evolution slide set
This set of three PowerPoint slides featuring personal response questions (i.e., multiple choice questions that can be used with "clicker" technology) can be incorporated into lectures on the mechanisms of evolution in order to actively engage students in thinking about evolution.

Las chinches de cama pican de nuevo gracias a la evolución
Las chinches de cama puede parecer un viejo problema pasado de moda, sin embargo ahora están de vuelta — y con venganza. Hace cincuenta años, estas plagas chupadoras de sangre estaban casi erradicadas en los Estados Unidos gracias, en parte, al uso de pesticidas como el DDT. Hoy, se arrastran entre las sabanas — y atormentan a los desgraciados soñadores — en todo el país...
