Beastman

Beastman (獣人, juujin) is a species of anthropomorphic animals that reside in the world of BNA: Brand New Animal.

Description
The scientific name of Beastman is Homo sapiens bestia. Beastman is the closest living ancestor to the human. They share a similar evolutionary lineage and their last common ancestor existed after the divergence of Australopithecus (~2 million years ago). However, their genetic data does not primarily use DNA, and instead uses beast deoxyribonucleic acid.

While some still live in hiding in predominately human-populated areas, the majority of beastmen live in a special exclusion zone known as Anima City. The reason of this is due to prejudice between both species, which is further exacerbated by controversies that surround the City's foundation.

Beastmen, while their true form is that of an anthropomorphized variant of any animal species, have the ability to change into a human form, with no obvious beastman traits present. Thus, it is easy for one to dwell among humans without raising alarm should they not revert back to their beastman form.

However there is a true blood beastman that can be hybrid of two animals.

Trivia

 * Beastmen while in their human form can unintentionally turn into their beatman form while under extreme emotion such as fear, anger, sadness and excitement. This may be a contributing factor as to why beastmen were not able to hide their existence.
 * It's unknown how exactly Beastmen biology work, Nakashima states that they are humans capable of turning into animals, but it is explained that they are actual anthropomorphic animals due to the beast factor while their human form is a disguise.
