Real animals exist for meat. There may also be regular dogs, cats, etc. Regular animals used to be more common, before Pokemon outcompeted them. The remaining wild animals are mostly small (like actual insects, as well as smaller birds and fish). Pokemon have a completely different molecular basis for life from humans and animals, so interbreeding with them is impossible.
Mostly, Pokemon were ultimately man-made. They existed as golem-like beings specifically designed to fulfill tasks. The legendaries were mostly intended to be superweapons, but all of them eventually fled due to their larger amount of allotted AI. Other Pokemon escaped or were abandoned in the wild, eventually differentiating to fulfill different ecological niches. Fossil revitalization is the only recreation of this forgotten technology that has been rediscovered.Pokemon are heavily influenced by human thought. That's why they become obedient and friendly with only short exposure to humans. Humans thought also subtly influences Pokemon differentiation in the wild, which is why so many Pokemon reflect human concepts.
Humans in the Pokemon world have mastered mass-energy conversion. This has drastically reduced the cost of almost everything, so there exists almost no abject poverty in the Pokemon World. Also, the instantaneous teleportation of goods has vastly reduced the need for infrastructure, rending most of civilization as isolated communities surrounded by vast swaths of wilderness.
Prior to this, wars over resources were as common in the Pokemon world as they are in ours. Mass-energy conversion did usher in an era of unprecedented peace, although it does create large demand for energy resources. Their renewable energy technology and infrastructure is much more developed, but dwindling nonrenewables remains a big concern.
