A scientific study reveals through ancient DNA that the 'giant crane' was a variant of the common crane
Researchers at Bournemouth University have determined that a supposed species of giant crane, cataloged in the 19th century, actually corresponds to a larger variant of the modern common crane. The conclusion was reached after analyzing ancient DNA extracted from 18 bones found at various locations across Europe.
The initial identification of the giant crane had historically been made based exclusively on the size of the fossilized bone remains, a common method in 19th-century paleontology but limited in the face of intraspecific variability.
To resolve this taxonomic mystery, the scientific team applied advanced extraction and analysis techniques of ancient DNA to a sample composed of 18 crane bones recovered from sites across Europe.
The genetic results demonstrated that the specimens classified as an independent species share the same ancestry as today's common crane, which necessitates a revision of the historical classification of these birds.
- The research was conducted by scientists from Bournemouth University.
- 18 crane bones found in Europe were analyzed.
- Ancient DNA analysis technology was used.
- The previous classification dated back to the 19th century and was based solely on bone size.
