Resume de l’article : Deux rares loups totalement noirs observés en Pologne

Response: Two completely black wolves were observed in Poland.

Explanation:
The article originally stated that two black wolves were spotted in the Biebrza National Park in Poland. This is unusual because gray wolves, the species to which these wolves belong, usually have a gray or brown coat. The discovery of these two black wolves is significant because it suggests that the gene responsible for black fur is present in the local wolf population. This gene is typically associated with dogs and was previously thought to be rare in wolves. The observation of these black wolves provides new insights into the genetic diversity and evolution of wolf populations in Europe.
