[Historical genesis of transhumanism: evolution of an idea].

The purpose of this paper is to show the historical continuity of transhumanism over time, from the birth of Darwinist eugenics to the present day. The history of transhumanism is rooted in the ideas of Francis Galton, who were assumed by the one who defined the current term, Julian Huxley. The influence of Huxley's thinking on present transhumanist philosophy cannot be considered marginal, as his philosophy was continued by the founders of the first transhumanist movements in the United States of America, F.M. Esfandiary and Timothy Leary. Both thinkers were the masters of today's transhumanists. This is how we seek here to establish a historical line from eugenics to today's transhumanism.
