Human

Humans are one of the most common sentient species in the "world". One estimate suggested that almost 80% of the world was human. They are spread across most of the world and they are often found in a variety of cultures and races that make them difficult to classify. They are so common that many use humans as a baseline for comparison. There are also many "near-human" creatures to be found that are either mutations of the original species, such as mutants, vampires or cyborgs. These are sometimes considered to be sub-species of human and add to the diversity and complexity of the species.

Description
Like many other sentient species in the world humans have two arms, two legs, a head and a torso. This basic shape is the most common design throughout the world covering almost 99% of all sentient species. As humans are the most common species this basic shape is often referred to as "humanoid", even by non-humans, for simplicity. Humans have two eyes that allow for colour sight and a visual range of 270° (including visual range when moving eyeball). The human eye is capable of smooth pursuit movement, allowing them to easily track moving objects within visual range. Humans have two ears that allow them to detect vibrations which the brain interprets as sound. Humans can hear between the frequencies of 20Hz and 20,000Hz. Humans are capable of olfacation, or smelling, through their noses. Women generally have a higher sense of smell than their male counterparts. Humans are subconsciously capable of detecting the scent of those related to them by blood. Humans use their mouths for breathing and eating. They are capable of tasting a wide variety of flavour groups, though children's sense of taste is much greater than the adults who lose almost half of their tastebuds before they reach twenty years. As with human appearence being the standard mode of comparison for most sentient beings in the world, so too is their sensory range. Often someone may suggest the average Elf has greater hearing than a human. The range of human hearing if often referred to as 'audio', the standard range of hearing. Humans have five digits upon their feet and their hands. Upon their hands they have the rare trait of opposable thumbs that allow them to use tools and is often joked as being the "key to sentience". Like the majority of species of the world humans come in two sexes, male and female. Being mammals the females have mammary glands allowing them to nurse their young with milk. Another mammalian trait, distinguishing them from other common groupings, is hair. Typically males will have much more hair than the females. Hair grows across their entire bodies but more prominently upon the tops of their hands and, in males, their faces. Hair is often styled by humans to express cultural values, such as religion or fashion. As men grow older they may lose this hair, particularly from the tops of their heads. Both sexes may lose their colour of their grey, turning to grey. Colouring of humans varies greatly and is often specific to the origins of their ancestors. Dark skinned humans are likely to have descended from people that lived in hot regions with plenty of exposure to the sun. Hair colour and type is often directly linked to ethnicity and is largely a genetic factor. Hair colour ranges massively depending upon their heritage and the planets that they, or their ancestors, originate from. Usually, however, colours range from black, brown, ginger, blonde, white. Any skin tone can have any variety of hair colour.

Story
It is unknown exactly why humans are seemingly the predominant species of the Multiverse. Some, especially human factions, claim it is evidence of a 'greater intelligence' (god), or that there is a 'perfect' evolutionary path and that, in both arguments, humans are the pinnacle. Others believe that the Multiverse often experiences 'echoes', causing a repeated characteristic from one universe to spread across the universal barrier into another. In this theory it is still unknown why the 'human echo' is so strong. These examples of humanity across the Multiverse differ greatly in every manner possible, but often the planet Earth is involved and is considered to be the homeworld of the human species. The very first settlers of "The World" were humans, now referred to as The Pioneers. Information on these individuals is largely speculative, especially their origins from their time before being in "The World".
