Scientists studying Eastern North American monarch butterflies have uncovered a suite of genes that may be involved in driving the butterflies to migrate towards Mexico for the winter. Their research describes 40 genes that are linked to the butterflies' compulsion to orientate themselves by an internal "sun compass" and begin the 4,000 km journey southwards.
