Chalicoman

Chalicoman is a sapient 5-7 foot tall upright bipedal-walking omnivorous Chalicotherium descendant that first evolved in Europe in 3 million years ago in the Pliocene period, making it the oldest sapient species to evolved and the first sapient being to spread across the world. They know about science, math, literature, religion, theory of evolution, etc. They even have their own culture, where they domesticated some plants including cherry blossom trees (for fruit) and other plants, they also have domesticated animals as food source or fur like European bison (like how humans domesticated cattle), red American hog (like how humans domesticated pigs), musk oxen (like how humans domesticated sheep), elk (like how humans domesticated reindeer), or for mounts or pets including giant horse (like how humans domesticated common horses), and domestic mokele (the domesticated mokele-mbembe (like how humans domesticated camelids), caracals (like how humans domesticated African wild cats, the wild ancestors of domestic cats), and dingos (like how humans domesticated gray wolves, the wild ancestors of domestic dogs).

Evolution
Around 9 million years ago, Chalicotheriums were struggling with the ever-changing climate and habitats, as well as new invaders including deer, bovines, and others, so the Chalicotheriums either had to adapt or die out completely. Around 7 million years ago, the Chalicotheriums have started eating meat by scavenging on carcasses, giving them larger brains for more intelligence, evolving from herbivores to omnivores. Around 5 million years ago, the descendants of Chalicotheriums have started to walk upright, walking for longer distance than their Chalicotherium ancestors, much like what happen to Australopithocines (the ancestors of humans) of 4-3 million years before present. Around 3 million years ago, the Chalicotherium's descendants have evolved into Chalicomen, which are now sapient and are now not just browsers, but also scavengers and predators. Eventually at the same time, Chalicomen have spread across the world (except Antarctica), where they evolved into different subspecies depending on the climate and habitat (example: the ones living in snowy environments evolved into woolly and stronger subspecies while the ones living in hot and dry environments evolved into shorter-haired and tailler subspecies).
