Humans are typically depicted as the dominant species of the planet Earth, and sometimes of other planets. Humans often mirror their real life counterparts in terms of abilities and intellect, while other times they can achieve superhuman feats.
Humans are the dominant species on the planet Earth. Typically human beings come in two genders; male and female, and as of 2013 the global average life expectancy at birth for females is estimated at 70.2 years compared to 66.1 for males. If you're reading this, chances are pretty good you're a human.
Human beings are featured in almost all anime and manga, though some series chronicle the lives of other creatures, terrestrial or otherwise. Like the real species they are based on, humans are typically depicted as the dominant species on the planet Earth, but this is not always the case.
For the most part, humans in anime and manga resemble their real life counterparts. However, many characters have eye and/or hair colors that do not occur naturally in the real world. Humans also sometimes have much greater potential than real humans, able to gain "superhuman" abilities of various kinds.
A popular idea in fiction is the possibility for humans to breed with other species, usually humanoid aliens, to produce hybrid offspring.
