Which observable physical traits are cited as visible markers resulting from the genetic divergence between dogs and wolves?

Coat color variation and floppy ears

The evolutionary divergence that separated dogs from wolves is clearly recorded in their DNA, but certain external physical changes also serve as visible markers of this genetic shift. Genetic studies highlight changes in traits such as floppy ears, variations in coat color, and alterations in cranial size as physical evidence of this split. However, it is important to note that these physical traits are considered secondary markers compared to the more fundamental neurological and behavioral adaptations that occurred during the domestication process. These physical markers represent changes traceable back to the *Canis lupus* ancestral stock.
