The team also found co-evolution in several brain processes — for instance, in genes that affect the processing of the brain chemical serotonin. To further their research, the authors of this paper suggest collecting data from even older populations of wolves and dogs, and utilizing other disciplines such as archaeology, anthropology and ethology (i.e., the science of animal behavior) to help pinpoint that precise moment where the first modern dogs originated. The researchers then identified a list of genes—including those involved in digestion, metabolism, cancer, and the transmission of serotonin in the brain—that are under... “As domestication is often associated with large increases in population density and crowded living conditions, these ‘unfavorable’ environments might be the selective pressure that drove the rewiring of both species,” the study authors wrote. The dogs are trained to stay motionless during the scans. A team of Finnish researchers have developed a new theory about dog domestication and the evolution of dogs from wolves.
