Did you ever wonder why dogs are so social towards humans? Even the friendliest wolf, does not compare to the friendliest Labrador retriever. It seems that the dogs today are wired differently then their ancestor, the wolf. Dr. VonHoldt and her colleagues may have found the exact gene that causes this difference in friendliness.
The genetic basis that causes the friendliness in dogs, may be similar/the same as the genetic basis that causes Williams- Beuren Syndrome.
Individuals with this disease suffer a developmental delay causing indiscriminate sociability.
Basically, what seems to cause problems with human development, is benefiting dog development.
The two genes associated with this disorder are GTF2I and GTF2IRD1.
** More experiments need to be completed before confirming this phenomenon/linkage.
