"The vanishing of the 1st American dogs"
Warum meldest du dieses Rätsel?
“It is fascinating that a huge population of dogs that inhabited all corners of the Americas for thousands of years could have disappeared so rapidly.”
"Evidence suggests dogs arrived in the Americas about 10,000 years ago. Some believe the ancient dogs looked a lot like present-day dingos." [above]
"The first dogs in America likely came … with people from Siberia, according to a new study by an international team of researchers.
"The research, which looked at ancient and modern dog DNA, suggests that populations of the so-called pre-contact dogs almost completely disappeared following the arrival of European settlers, leaving little or no trace in more modern American dogs.
"It has long been a matter of dispute whether these first American dogs survived in some form, perhaps only as a portion of the DNA in some breeds or mixed breeds of today’s dogs. But the study, published July 6, 2018 in the peer-reviewed journal Science, overwhelmingly suggests that the pre-contact dogs have disappeared. The evidence found no more than 4 percent of pre-contact dog DNA in any sample.
"Anna Linderholm, assistant professor of anthropology at Texas A&M University, did much of the genome work. She said:
"'The sudden disappearance of dogs in America was probably associated with European colonization, but we don’t know the details yet. This is further evidence of the strong bond between humans and dogs. Humans will bring their dogs to every new place they explore and colonize, regardless of time and space.
"'When we compare our ancient dog DNA to all other known dog/wolf DNA, we find that the closest relatives are the Siberian dogs. This mirrors what we know about humans at the time and sites in Siberia have records of people using dogs then.'"
