Most experts agree that dogs predate the invention of agriculture (which happened roughly 10,000 years ago), but some say that domestication may have occurred as long as 100,000 years ago. The first recognizable dog (canids) to be distinguished from early carnivores appeared in the fossil record during the early Oligocene.

Turning off the personalised advertising setting won’t stop you from seeing Etsy ads, but it may make the ads you see less relevant or more repetitive. Dogs have been bred as pets and companions for thousands of years with the earliest known domestication taking place over 12,000 years ago. In this Perspectives, we discuss the origins of dog skull shapes in terms of history and biology and highlight recent advances in understanding the genetics of canine skull shapes.As museums continue to add DNA preservation as a facet of their repositories and as sequencing technologies continue to improve, it is possible that dog morphology association studies using direct phenotype–genotype relationships will be possible. However, as the cost of targeted sequence capture and next-generation sequencing continue to decrease, fine-mapping regions of extensive LD should become less problematic, enabling unprecedented haplotype resolution and prioritization of genetic variation for further investigation.

A) Surface scans of a wolf skull morphed to illustrate the differences between brachycephalic, ancestral, and dolichocephalic skull states of canids are shown. Extrapolating from this short list of candidates, it is clear that FGF and TGF-β signaling are integral for maintaining patency and growth at the sutures and synchondroses (supporting information, Table S1; Online Mendelian Inheritance in Man 2012).This observation raises the possibility that mixing and matching genetic variants that independently regulate development of either structure enrich canine skull diversity. Dogs were the first species to be domesticated by hunter-gatherers over 15,000 years ago before the development of agriculture.
