Sleddog DNA revealed the hidden chapter in the history of Greenland

Invit had arrived in Greenland several hundred years ago, according to a study, the genetics of the solid dogs made by researchers from the University of Copenhagen, including the University of Copenhagen, were mapped.

For many of us, dogs are our best friends, but in Greenland, Slage dogs have been more than just loyal peers for centuries: they are an indispensable manpower, are partners in hunting and are pulling sled in the country’s icy regions.

Now, the Genome of Slage Dogs is rewriting a part of the history of Greenland. In the new research published in ScienceFor the first time, researchers have found genetic evidence that today’s Greenland population’s ancestors traveled with Canada several hundred years ago from Canada to a larger island from Canada.

“So far, we believed that the invoice had arrived in Greenland 800 years ago, but the Slage Dog Genome shows that 200-300 years ago,” says Anders Johannes Hanson, one of the researchers behind the research in Copenhagen’s Global Institute and researchers behind the research.

Jane shows evolutionary date

In almost 1,000 years, when Invites and Sled Dogs live together in Greenland, their dates are deep. As a result, the collective genetic material of dogs shows important details about the movement of the initial invoice population.

By testing that dogs are closely related to each other and their ancestors of North America, researchers take insights when the interval from Canada took place and when groups of solid dogs, along with humans, settled in various regions of Greenland.

“We are detecting human migration through their sled dogs,” says the main author of the study, Copenhagen University and the US National Institute of Health of Health. Health Tatiana Favaron says.

“This is the first time when we have genetic evidence when we arrive, to identify it, and then divide it into four groups that were settled in isolated areas,” Favarin explained.

Dog genome not only reflects geographical changes, but also reflects periods when the population of a sled dog decreases due to illness or appetite – patterns that researchers can read in DNA.

Climate changes and snoo motorcycles have threatened sled dogs

Although the Slage dogs and Greenland are deeply connected, their numbers are decreasing year by year. The climate change and the rise of the snooping motorcycles are partially responsible for the fall of these traditional working animals.

“Due to the withdrawal of sea snow, sled, can only be used in short periods of years and more limited areas,” says Anders Johannes Hanson. In combination with the use of Sno -Motorcycles, it means that fewer people keep sled dogs. “

He added, “If we want to protect sled dogs in the future, we need data about how a genetically healthy population looks like – and this is what the study provides.”
