Razib Khan One-stop-shopping for all of my content November 19, Filed under: DingoDog domestication — Razib Khan Additionally, unlike other feral lineages hybridization with other populations has been pretty minimal until recently though they detected some in two of their dingo samples.
And this clade is most similar to Indonesian dogs. Their ancestral population is really, really, small. That divergence is probably sensitive to some parameter estimates. But, it does make me wonder who the domestic dogs came with.
Since they seem to be descended from Eurasian wolves, the most likely candidate is the first Austro-Asiatic farmers. From them, dogs could spread rapidly through feralization to neighboring populations of hunter-gatherers.
Selection analysis identified 99 positively selected genes enriched in starch and fat metabolism pathways, indicating a diet change during feralization of dingoes. Interestingly, we found that 14 genes have shifted allele frequencies compared to dogs but not compared to wolves.
This suggests that the selection affecting these genes during domestication of the wolf was reversed in the feralization process.
This suggests that ARHGEF7 may have been under selection for behavioral adaptations related to the transitions in environment both from wild to domestic and from domestic back to wild.
Our results indicate that adaptation to domestication and feralization primarily affected different genomic regions, but that some genes, related to neurodevelopment, metabolism and reproduction, may have been reversibly affected in the two processes.
There are lots of arguments about how the dog got domesticated. One thing to remember is there is a distinction between population divergence of the ancestors of dogs from the ancestors of Eurasian wolves and the domestication of the dog in various steps and stages.
One can imagine, for example, a close association between some groups of wolves and humans, with the former existing in a symbiotic relationship with nomadic bands.
This state could persist for thousands of years in fact, I have heard that this may resemble the relationship of the dingo to Aboriginal people, whose landscaping through fires may have been helpful to dingo predation.
Eventually, though humans settled down into sedentary villages. The dingo may illustrate a shift back toward more detachment from humans. The Aboriginal people never lived in large agricultural villages, so the opportunities for extremely close coexistence did not present themselves.
But it is interesting that the dingo did not revert to becoming an Australian wolf, but remained distinctively dog-like. This may be a function of loss of genetic diversity through the bottleneck, a different ecological niche than the wolves of Eurasia, or, irreversible evolutionary genetic changes in the morphology and physiology of the canid lineage.
