UPDATE ON THE GENETIC STUDY OF ARABIAN DESERT DOGS
Some results of the genetic study under way of our Arabian pariah desert dogs have been shared with me by Dr.Elaine Ostrander and her team at the National Institute of Health. All dog have now been identified. (See below).
The dogs cluster in 2 groups, one showing a genetic connection to Basenjis. This is not surprising considering that Basenji dogs would have been established from dogs that moved to Africa through the middle-east so some of their genetic material would be expected to still be found among dogs of the middle-east. Basenjis have evolved separately now for some time.
The second cluster is with what is now human controlled “breed” registered as Canaan dogs. These have the same genetic origin with Canaan dogs having been selected from a small number based on appearances without reference to their genetic makeup, since such testing was not available when the breed was established several generations ago. It is to be expected that pedigree Canaan dogs would now have less genetic diversity than our pariahs.
The dogs included in this ongoing work include some born in Jeddah, Al Qassim, Riyadh, Dammam, Doha, Dubai and other emirates and Sohar. All of them have an ancient connection and are not mixes of modern dogs. Some had been adopted and living in homes or were in K9 friends, Dubai shelter and some were still living free but were being provided with food and water and had become accustomed to people.
First is the overall tree as published previously by Elaine Ostrader et. al. It shows where Canaan dogs fit in the world of dog genetics but our dogs had not been included when published.
The second diagram is an enlarged small section of this tree with our desert dogs added and shown in red. As explained by Dr. Ostrander :-
- Small numbers on the lines in black are the bootstrap values. That indicates how many times out of 100 we ran the same data and got the exact sample architecture of the tree. This tree is amazingly good with most data being at 100%.
- The Canaan dogs are not necessarily closet to the Saluki. Remember that this is a two dimension graph that can exist in three dimensions. So the branch with the Saluki can be flipped 180 degrees, putting them closer to anything left of the saluki. What matters here is the branch position. Like a real tree--what is relevant is what branch comes from which larger branch, not the twisted position of the single small branch. So focus on the branch structure. "
Photographs of the dogs included in these groups and identified follow. First those clustered with Canaan dogs then those clustered with Basenjis.
THANK YOU FOR ALL WHO PARTICIPATED IN THIS, WITHOUT YOU WE COULD NOT HAVE DONE IT. THESE DOGS ARE IMPORTANT AND DESERVE FULL RECOGNITION AS A PART OF THE NATIONAL HERITAGE OF THIS PART OF THE WORLD AND THE OVERALL WORLD OF DOGS. As more information comes to hand I will update it.
