The genes of the first dogs of North America studied

OXFORD, ENGLAND – The mitochondrial DNA of former North American dogs has not been found in any other dog, according to an article published in Science Magazine . A genetic study of dogs that lived in North America and Siberia between 1,000 and 10,000 years ago revealed that the genetic makeup of older American dogs is very similar to that of 9,000-year-old dogs on the island. from Zhokhov, north of Siberian. Mainland. A study of nuclear DNA dogs also supports the idea that former North American dogs were genetically distinct from today 's animals, but related to arctic breeds such as malamutes. Alaska and the Siberian huskies. The evolutionist geneticist Lawrence Frantz of Oxford University suggests that the genetic mutation rate indicates that former North American dogs and Siberian former dogs shared an ancestor about 16,000 years ago or the time when humans migrated to North America. Dogs may have traveled to the New World with humans, or they crossed the Siberian land bridge to North America afterwards, but before the land bridge disappeared 11,000 years ago . According to Australian archaeologist Angela Perri of the University of Durham, the first North American dogs were probably wiped out by diseases introduced into the New World by the dogs of European explorers or were killed by suspicious Europeans frightened by their wolf appearance.
