Miacis - The Ancestor of Modern Carnivores, Including Wolves and Dogs

This article explores Miacis, a small carnivorous mammal from the Paleocene–Eocene (~62–33 million years ago), regarded as the ancestral root of modern Carnivora. With its civet-like body, long tail, and arboreal lifestyle, Miacis was an omnivore feeding on insects, small animals, and fruits. Although not a dog itself, Miacis is the common ancestor of today’s quadrupedal carnivores, including the gray wolf (Canis lupus) and the domestic dog (Canis familiaris).
