    Monarchs are perhaps best known for their migration, but until recently scientists had relatively little genetic data about their behaviour. Now an evolutionary biologist at the University of Chicago and his colleagues have used the latest statistical tools to delve into the Monarch’s secrets. The team sequenced 101 genomes from Monarch populations across the globe along with those of their close relatives, then ran comparisons looking for clues. They published the results and what they showed yesterday in NATURE magazine (scientific journal).

    Now it be can proven that:

    1. Monarchs originated in North America.

    2. The earliest Monarchs were probably migratory.

    3. Migratory ability is tied to a single gene.

    4. Monarch wings share their colour genes with mice.

    5. Migration may be on the decline in Monarchs.
