| Summary: | Adaptations allowing dogs to thrive on a diet rich in starch, including a significant AMY2B copy number gain, constituted a crucial step in the evolution of the dog from the wolf. It is however not clear if this change was associated with the initial domestication or represents a secondary shift related to the subsequent development of agriculture. Previous efforts to study this process were based on geographically limited data sets and low-resolution methods and it is therefore not known to what extent the diet adaptations are universal among dogs and whether there are regional differences associated with alternative human subsistence strategies. Here we use droplet PCR to investigate worldwide AMY2B copy number diversity among indigenous as well as breed dogs and wolves to elucidate how a change in dog diet was associated with the domestication process and subsequent shifts in human subsistence. We find that AMY2B copy numbers are bimodally distributed with high copy numbers (median 2nAMY2B=11) in a ... : Supplementary_table_1Summary of all dogs analysed in this study. “AMY2B copy numbers”: Rounded AMY2B copy number of individual; “Name”: name of dog lineage (breed name or name of native dog population if applicable); “Native/Breed”: states whether the individual was analysed as a breed or a native dog; “Country of origin” and “Region of origin”: see Methods section for information on how geographical origin was set,: “Culture”: set to agrarian or non-agrarian depending on whether region of origin overlaps with the approximate spread of pre-historic agriculture.Supplementary_table_2Summary of other canids analysed in this study. “AMY2B copy numbers”: Rounded AMY2B copy number of individual.Supplementary_table_3Summary statistics of AMY2B copy number distribution in dogs. AMY2B copy number distribution in breeds for which at least two individuals were genotyped and in all native dogs grouped into 8 geographical regions (Africa, South West Asia (S. W. Asia), South Asia (S. Asia), East Asia (E. Asia), South East ... |
