Researchers used genetically modified bacteria as a model to help explain how a developing animal keeps all of its parts and organs in the same general proportions as every other member of its species. By combining two chemical signals with a few variables, timing cues emerge that can not only create patterns, they can also make sure these patterns have roughly the same proportions from one bacterial colony to the next.
