Epigenetic Alterations Determine Ant Behavior

Tweaking the proteins that control how tightly DNA is wound can dramatically alter behavior in Florida carpenter ant workers, according to researchers who manipulated the biochemistry of the insects. Researchers have long pondered the biological roots of divisions of labor that exist in genetically similar eusocial insect colonies, and the new study suggests that epigenetic modifications may be key to behavioral differences that delineate castes in such animals.
