From Wikipedia, the free encyclopedia

A posthuman or post-human is a hypothetical future being whose capabilities so radically exceed those of present humans as to be no longer human by current standards. A posthuman can also be described as the creature that results from radical human enhancement. In these ways, the difference between the posthuman and other hypothetical sophisticated non-humans is that a posthuman was once a human, either in its life time or in the life times of some or all of its direct ancestors. As such, a prerequisite for a posthuman is a transhuman, the point at which the human being begins surpassing his own limitations, but is still recognisable as a human person.
