Recent genetic research indicates that this behavioral variation is highly heritable.. Most modern dog breeds were developed in an intentional, goal-driven manner relatively recently in evolutionary time, Hecht et al recognize, between the past few thousand to the past few hundred years. 2022 TrendingBreeds.
