Digging Deep in the DNA – How Genes Control Complicated Behavior.

The investigation of the genetics of behavior is a huge scientific enterprise, with great progress being made in a variety of species — roundworms, fruit flies, lab mice, sticklebacks. Dr. Hoekstra’s work is unusual in that it deals with a naturally occurring, complicated behavior in mammals that is important for survival. And it is significant that she has been able to separate that behavior into two modules controlled by separate and independent DNA regions — burrow length, and escape tunnels.
