Anthropoid

Anthropoids (or anthros) are the dominant population after the disappearance of the human race. They are composed of dozens of species of mammalian animals, genetically engineered to be bipedal and sentient.

History
After humanity had been wiped off the surface, anthros rose to take their place. They had been created by humans in genetic experiments, and survived the extinction. Anthros eventually replaced humans and took over their culture. Technology was provided to the population by the Jackal clan. The jackals had stumbled upon a surviving population of humans, and traded energy sources for technology. However, they kept the existence of humans a secret and pretended to have invented the technology. Eventually, anthros had reached 21st century advancements.

Description
Anthros are made up of exclusively mammals. Species range from all over the world. Anthros have furred humanoid bodies, with two upright legs and two arms and hands with opposable digits. However, their heads and tails are retained from their feral forms. Reptiles, birds, and insects appear in their natural form, and no anthros of these types are seen.

It appears that anthros of different species can breed, and the offspring take on the species of their same-gender parent. For example, Max Williams is a white cat, like his father, and unlike his mother, who is a white tiger.
