Rare black wolves for the first time in history were captured by crossing a stream in Poland: this was the first case when the black wolves were photographed in the country. Personnel of a rare species of animals were made by feathers established by scientists to observe the beaver, writes iflsciens.

It is known that the photoeepers were installed by researchers from the Save Wildlife Conservation Fund Poland charity organization.. Initially, one gray wolf and one black wolf crossing the stream, and then two black wolves and gray wolf, which later cross the same stream, are visible on the frames.

In local folklore, there are stories about black wolves, but earlier scientists have never seen them firsthand. In the 1950s, the wolves in Poland almost died out, but in 198, a national ban on hunting for wolves was introduced in Poland, which helped the population begin to recover.

Recent studies have shown that Polish wolves are now mobile, crossing borders with neighboring countries. Scientists suggest that today about 2,000 wolves wandering around Poland and in its district. It is assumed that two black wolves noticed in Poland are a brother and sister, for about a year. Given the personnel, the charity organization now wants to raise money for the collection and analysis of the litter of the couple in order to learn more about their DNA and genetics.

In Yellowstone, the re-settlement of wolves in the 1990s literally changed the landscape as a result of the phenomenon known as the trophic cascade. According to the study of 2022, although black wolves are rare around the world, almost half of the wolves in Yellowstone are black.

Scientists do not know why the wolves became black, but they suggest that an unusual color occurred due to a mutation of home dogs bred with wolves thousands of years ago. It is known that most wolves in Poland are gray with red and black accents. According to Joanna Tochidlovsk, the cooradicator of the Save Wildlife Conservation Fund Poland, they also found that black and gray wolves are actually the same form.

Genetic states that affect the appearance of animals are quite common and can lead to the fact that all individuals will become black, or even make some species white.
