prehistoric wolf still found in baltic island Recommended for humans take care of wolf thousands of years ago dog According to a new study, it appears.
archaeologist Relics dating from 3,000-5,000 years ago were found in the Stora Förvar cave swedish island Stora Kalser. The cave shows signs of heavy use by sealers and fishermen Stone Age and Bronze Age, Researchers from Stockholm University said.
The island is only 2.5 square kilometers in size and has no sign of any native mammals. Because of this isolation, researchers believe Wolf It was brought by people, probably by ship.
dog Originally appeared in Wolf During the Paleolithic Age, before other domestications animal. But where and how many times domestication occurred remains unclear.
One leading theory is that wolves gradually adapted to life near humans, while another theory proposes that people began raising wolf pups in captivity from a young age. No remains of dogs from the earliest stages of domestication have yet been found.
New evidence shows wolves and humans lived together on Earth Sweden islands may point to prehistoric Domestication of wolves.
DNA analysis of two bones found in the cave confirmed that the animals were wolves rather than dogs, with some characteristics suggesting the canines were in close contact with humans.
One of the wolves appeared to have survived but suffered injuries to its limbs, making hunting difficult, suggesting it was cared for.
“Finding these wolves on a remote island was completely unexpected,” said Linus Girdland-Flink of the University of Aberdeen, one of the authors of the study published in the journal. Proceedings of the National Academy of Sciencesexplain.
“Not only are they indistinguishable from other Eurasian wolf ancestors, but they appear to have lived alongside humans, eating human food, and in a place only accessible by boat.”
While it’s unclear from the fossils whether wolves were tamed, kept in captivity or otherwise managed, the findings suggest that the relationship between humans and wolves was much more diverse than previously thought.
Interactions between humans and wolves in the cave appeared to involve close cooperation, suggesting that early domestication experiments did not directly lead to the creation of modern dogs, scientists say.
“While we cannot exclude that these wolves have lower genetic diversity due to natural causes, this suggests that humans interact with and manage wolves in ways that we have not previously considered,” said Anders Bergström, another study author at the University of East Anglia.
“This is a controversial case that raises the possibility that, under certain circumstances, humans were able to raise wolves in their settlements and found value in doing so,” said study co-author Pontus Skoglund of the Francis Crick Institute.
