Jul 6, 2018 · The earliest New World dogs were not domesticated from North American wolves but likely originated from a Siberian ancestor. Furthermore, these lineages date back to a common ancestor that coincides with the first human migrations across Beringia.
In 2021, a literature review of the current evidence infers that domestication of the dog began in Siberia 26,000-19,700 years ago by Ancient North Eurasians, then later dispersed eastwards into the Americas and westwards across Eurasia.

Modern dogs evolved from a line of carnivorous mammals called "canids," after the characteristic shape of their teeth. Before (and alongside) the canids, though, there were such diverse families of predators as amphicyonids (the "bear dogs," typified by Amphicyon, which seem to have been more closely related to bears than dogs), prehistoric hyenas ...
Paleontologists agree that the late Eocene(about 40 to 35 million years ago) Hesperocyon was directly ancestral to all later canids — and thus to the genus Canis, which branched off from a subfamily of canids about six million years ago. This "western dog" was only about the size of a small fox, but its inner-ear structure was characteristic of lat...
Here's where things get a bit confusing. Shortly after the appearance of Hesperocyon 40 million years ago, Leptocyon arrived on the scene — not a brother, but more like a second cousin once removed. Leptocyon was the first true canine (that is, it belonged to the caninae subfamily of the Canidae family), but a small and unobtrusive one, not much bi...

Hybridization with wolves and coyotes may have been an old practice contributing genetic diversity to pre and post-Columbian American dogs. Archaeological, historical, and ethnographic records reveal dogs being used for hunting, transport, food, rituals, company, and defense.
