The rock pocket mouse is a living example of Darwin's process of natural selection. Not only is evolution happening right now everywhere around us, but adaptive changes can occur in a population with remarkable speed. This speed is essential if you're a desert mouse living in an environment where a volcanic eruption can reverse selective pressure in nearly an instant. Features Dr. Michael Nachman, whose work in the field and in the lab has quantified the selective pressure of predators and identified the genes involved in adaptation. From ecosystem to molecules, pocket mice show the viewers how random changes in the genome can take many paths to the same adaptation-a colored coat that hides them from predators.

Dr. Jeffery Friedman introduces the genes and circuits that control appetite, including the key role of leptin. Part of the 2004 Howard Hughes Holiday Lecture Series.
Researchers Randy Jirtle and Rob Waterland work with agouti yellow mice to study the implications for cloning, nutrition, and disease research. Their research has been called one of the most important studies of the 21st century. It is hugely significant for understanding the relationship between genes and the environment.
Infrared light is all around, and the universe literally glows with it everywhere. However, humans are not able to see infrared light because it is just outside the limits of the human eye. With a simple injection, scientists gave mice the ability to perceive near-infrared light. What does this mean for humans? Part of the "Uno Dos of Trace" series.
The rock pocket mouse is a living example of Darwin’s process of natural selection. Not only is evolution happening right now everywhere around us, but adaptive changes can occur in a population with remarkable speed. This speed is essential if you’re a desert mouse living in an environment where a volcanic eruption can reverse selective pressure in nearly an instant. The film features Dr. Michael Nachman, whose work in the field and in the lab has quantified the selective pressure of predators and identified the genes involved in adaptation. In a complete story, from ecosystem to molecules, pocket mice show us how random changes in the genome can take many paths to the same adaptation—a colored coat that hides them from predators.
