The brain size of present-day dogs is increasing as they move evolutionarily away from their ancestral wolf.
Tibor Csörgő, a senior research fellow and a co-author in the study, has been collecting canine skulls for decades. The team analyzed the CT scans of the skulls of 159 contemporary dog breeds to estimate the brain cavity volume, with 48 specimens representing wolves.
As per the results published, wolves with an average body weight of 68 pounds have an average brain volume of 131 cm3, in comparison to the dogs in the similar weight category who have an average brain size of 100 cm3. Although this confirmed that domestication has had a similar effect on the brain size as observed in other species, the team was perplexed to discover that the more distantly a dog breed is genetically linked to wolves, the larger the size of its brain would be.
"The results show that the breeding of modern dog breeds has been accompanied by an increase in brain size compared to ancient breeds. We couldn't explain this based on the tasks or life history characteristics of the breeds, so we can only speculate about the reasons," added Kubinyi in aThe study suggests that potential links between brain structure and other traits in dogs could be enhanced in future studies in the field of brain evolution in dogs.
