Secret of connection between dogs and humans could be genetic

While the canine human connection is an accepted norm in today’s world, it is nonetheless a puzzling enigma to scientists, who wonder at the oddity of the evolutionary turn that took a wild animal, with no kinship to humans, to a place where such kinship seems almost fated. New research, that looks for genetic common ground among dogs that tested positively at tasks aimed to discover those animals willing to seek out human assistance, suggests that a genetic sequence, found in some canines, could suggest a need, or willingness, to bond with humans.

Key Takeaways:

  • Scientists have found a handful of genes that they may be linked to the tendency for dogs to seek human help and contact.
  • The results revealed variations within two genomic regions that appear to be linked with a canine yen for human contact, within which five genes were identified as being the most likely to be associated with the behaviour.
  • “We also know that the genetic contribution to this variation is only about 30%, so 70% of the variation has to do with things like experience,” said Jensen.

“Scientists say they have found a handful of genes that appear to be linked to the tendency for dogs to seek human help and contact.”
