The Tuatara,
Sphenodon punctatus, is a unique reptile found in New Zealand. New research suggests the species has two mitochondrial genomes. (Robert Sprackland)
250 million years ago, many tuataras roamed the world. Now, only one species remains. In fact, the modern tuatara,
Sphenodon punctatus, is the only surviving family member of its taxonomic order,
Rhynchocephalia.
Today, a new paper in
Communications Biology suggests there is something even more remarkable about this little survivor. Scientists have now found that the species may have two mitochondrial genomes, making it unlike any other vertebrate in the world.
All animals have nuclear DNA found in the cell’s nucleus and mitochondrial DNA, located in the so-called cellular “powerhouse,” the mitochondria. By examining both types of genomes, scientists are building pictures of countless species evolution throughout millennia.
