Geisha (Species)

A geisha is a species of hominid that originated from Asia and, unlike common humans dressed up as geishas, they don't wear very colorful kimonos, as they aren't appropriate for the real geishas. They aren't actually born without kimonos, since they are made by clowns using common human-made technologies so they aren't naked, unlike their ancestors in prehistoric times. They are called geishas because of their bright black hair, literally white skin, slightly large incisors, and natural, unwashable makeup. Unlike in movies, TV shows, games, etc, they don't really entertain people much (unless if they were trained to entertain) and none of them are killers/evil nor are they scary, they just look very bizarre for a hominid species. Also unlike humans, geishas do not get fat/obese problems, so there are no fat geishas in real life, so all geishas of every geisha subspecies are skinny and somewhat muscular in build, and they are slightly stronger than the common human.

Evolution
Around 30,000 years ago, a prehistoric group of homo sapiens had migrated to the forests of Japan, where they were struggling to adapt in the new environment without any of their tools. In order to adapt, some groups of these homo sapiens had developed slightly larger and longer incisors, which, in nature, were designed to strip wood off of branches and tree trunks to reach the insects inside of trees. They also developed bright green coloration in their hair, with males being much longer than that on females, possibly to attract mates, but their hairstyle is permanent. They also have lighter skin colors possibly due to they were once nocturnal. Eventually around 80,000 years ago, these advanced hominids evolved into geishas (homo geishanis). As homo sapiens that remained mostly unchanged came and modified many (but not all) habitats, the geishas have adapted to the changing environment by becoming less solitary and more tame/friendly. They have also adapted to become fully-sapient in order to thrive well in cities. They have also adapted to feed on not just insects, but also fish, frogs, lizards, birds, eggs, small mammals, carrion, and man-made food as an effect of their adaptations to life in cities. Due to their new sapience, they have spread to the rest of the world's continents, except Antarctica, where it is too cold for geishas to live in.
