Jellyfish with up to a dozen heads have been created in the laboratory by carefully monkeying with a few genes.The genetic experiments could shed light on how natural colonies of other multi-headed organisms first originated, including some that build coral reefs.
Researchers targeted so-called Cnox genes, which help control how the bodies of jellyfish are laid out as their embryos develop. These genes are closely related to Hox genes, which play a similar role in humans.
