A major wildlife finding is making waves in Europe news after researchers concluded that the rabbit long treated as a single Iberian species is actually two distinct species with separate evolutionary histories. The discovery, which also carries relevance for ireland news and wider irish news audiences following biodiversity and conservation policy, could reshape how rabbit populations are protected across Spain and Portugal.
A research team involving Spain’s CSIC and partner institutions in Portugal and the UK says the animals split around two million years ago. Their study argues that what was once grouped under one label should now be recognised as the Iberian rabbit, Oryctolagus algirus, and the European rabbit, Oryctolagus cuniculus.
Europe News: Why the rabbit discovery matters
For decades, scientists believed rabbits on the Iberian Peninsula belonged to one species with regional variation. The new research challenges that assumption by showing the two lineages evolved separately after becoming isolated in different glacial refuges: one near the Ebro valley and the other around the Gulf of Cádiz.
Their outward appearance is similar, but researchers say the differences run deeper than genetics. The Iberian rabbit is described as:
- Smaller in size
- Darker in fur colour
- Producing smaller litters
- Reaching sexual maturity earlier
- Having a different gut microbiome and parasite profile
These traits suggest the two rabbits are not simply local varieties, but separate species that have followed their own evolutionary path for nearly two million years.

Conservation concerns in Spain and Portugal
The most important consequence of this finding is conservation. While the European rabbit remains stable or even abundant in some areas, the Iberian rabbit is declining across Portugal and south-western Spain. Treating both as one species may have hidden how serious the drop has become.
Researchers warn that restocking for hunting has often introduced European rabbits into areas where the Iberian rabbit naturally lived. That raises the risk of:
- Competition for habitat and food
- Hybridisation between the two species
- Gradual replacement of the rarer Iberian rabbit
This matters beyond rabbits themselves. Rabbits are a key prey species for around 40 predators in Mediterranean ecosystems, including the Iberian lynx and the Spanish imperial eagle. Any decline can ripple through the wider food chain.
What formal recognition could change
If conservation bodies formally recognise two species, governments and wildlife managers could create species-specific plans, including tailored monitoring, recovery strategies and hunting rules. That would be a significant step in biodiversity protection policy across southern Europe.

Why this matters beyond the Iberian Peninsula
This story has broader scientific relevance in Europe news because it highlights how taxonomy can lag behind evolution. Similar revisions have happened before with giraffes and African elephants, where modern genetic evidence revealed hidden diversity within animals once considered single species.
For readers interested in ireland news, the case is also a reminder that wildlife classification influences environmental law, land management and conservation funding. In an era of climate stress and habitat pressure, accurate species identification is essential.
Conclusion
This Europe news development shows that even familiar animals can still surprise science. Recognising two separate rabbit species in Iberia is more than a naming update: it could determine how vulnerable populations are monitored, protected and managed in the years ahead. For policymakers, researchers and readers of irish news, the takeaway is clear: better science leads to better conservation.
FAQs
What did scientists discover about rabbits in Spain and Portugal?
They found that rabbits on the Iberian Peninsula are likely two separate species, not one species with regional differences.
What are the two rabbit species called?
The study identifies the Iberian rabbit as Oryctolagus algirus and the European rabbit as Oryctolagus cuniculus.
Why is the discovery important?
Because the Iberian rabbit is declining, and treating both rabbits as one species may have masked the conservation crisis.
Where is each species found?
The Iberian rabbit occurs naturally in Portugal and western Spain, while the European rabbit dominates eastern parts of the peninsula.
