Unlike Their Wild Cousins Wolves, The Friendly Nature Of Dogs In Communication And Interaction With Humans Is Based On Genetic Differences!

Now, scientists say that the extreme friendliness of the two species can be based on the same genetic origin. (Williams syndrome = happiness disease)

Williams syndrome is caused by the loss of 27 genes in human DNA. The syndrome occurs in one in 10,000 people. People with the syndrome are cheerful, extroverted, broad forehead, plump cheeks, heart disease, mental and physical, especially people prone to music, are connected to some mental and physical.

A gene called WBSCR17, or genes close to it, is thought to play an important role in the evolution of dogs. This genome region has similarities in dogs and humans. The human version of the WBSCR17 gene is located close to the deleted gene sequence of people with Williams syndrome. The scientists pointed out that the only genetic attachments known as “transposons” in Williams Syndrome could explain why dogs approach humans in search of physical contact, help and information.
