Why this matters

The domestication of dogs from wolves represents a pivotal moment in human-animal co-evolution, profoundly shaping canine physical and behavioral traits. This research is significant as it delves into how human selective breeding practices have not only altered external characteristics but also the very structure and function of dog brains, leading to distinct breed-specific neurological differences. Understanding these changes provides crucial insights into the mechanisms of domestication and the intricate relationship between genetics, environment, and brain development in a highly successful species.
