Cybernetic evolution. Conceptual computer artwork of the evolution of a cybernetic human. From left to right, the sequence shows the stages that led, over more than a billion years, to modern humans (second from right). Single nucleated cells (far left) were followed by: multi-cellular life; fish; amphibians; small mammals; primates; early humans; and modern Homo sapiens. Advances in computer and medical technology may lead to a new stage in this evolution: the creation of cybernetic humans (far right).
