Canine diversity: Why are dogs the most diverse mammals on Earth?
Dogs, known as man's best friend, have more than 360 globally recognized breeds and are the most diverse mammals on Earth. Each dog breed was purposefully bred by humans for a specific task, ranging from herding and hunting to guarding. This diversity is reflected not only in their appearance, size, and hair characteristics, but also in the huge variations in behavior and personality.
These dog breeds have unique morphological characteristics, including body size and shape, tail type, and coat type.
Most dog breeds descend from a small number of ancestral dogs and have evolved rapidly over the past 200 years. Because of their ability to adapt to a variety of environments and their ability to reproduce according to human needs, dogs have become the most common carnivorous animals on earth. Each breed consistently produces corresponding physical characteristics, movements, and personalities, developed through decades of selective breeding.
History and development of dog breeds
Before the Victorian era, there were many types of dogs that were defined by their unique features. As society changes, the role of dogs also changes. To some extent, appearance has replaced function and become the focus of evaluation. The process of standardization of dog breeds has accelerated as breeders have sought to develop dogs with specific characteristics and an ideal appearance.
Driving this change are dog shows and the groups that run them, which are giving the word "breed" a whole new meaning.
Origins of modern dog breeds
As early as a 2017 study, scientists discovered that modern dogs appeared on Zokhov Island in Siberia as early as 9,000 years ago, when they were selectively used as sled dogs and hunting dogs. It also shows that specific breed standards already existed at that time. The maximum size of ancient sled dogs was between 20 and 25 kilograms, which is consistent with the modern Siberian Husky standard. Over time, many modern dog breeds have been derived from these early breeding practices.
Genetics and behavioral diversity
According to genetic studies, dogs show amazing diversity in morphology and behavior. The differences in these traits arise from genetic variation and differences in habitat. Size differences between dog breeds can be traced back to specific genetic variants, which continue to be influenced by human selection. Each breed exhibits unique behaviors for specific functions, such as guarding, herding, and hunting, further demonstrating the close connection between dog diversity and human needs.
Today, dogs are not only the most numerous carnivorous animal in the world, but also show their cultural and functional diversity in various regions.
Establishment of dog breed standards
Major dog associations and breed registries typically maintain and publish breed standards, which are descriptions of the ideal breed's appearance and temperament. As time has passed, many unrecognizable dog breeds have continued to exist, which possess superior genetic traits but cannot be officially recognized due to the lack of appropriate registration procedures.
