Homo Sapiens 1900 is a 1998 documentary directed by Peter Cohen, about various eugenics methods that were in practice in Europe during the first part of the 20th century.
Eugenics is to be the scientific credo of the 20th century. The man credited with its invention, Francis Galton, says it is based on the concept that the evolution of man is crippled by the ill-conceived – those unfit to breed. The study of eugenics thus would concern itself with distinguishing the weed from the good flowers.
Eugenics offers two approaches: positive eugenics, and negative eugenics. Positive eugenics aims towards creating better humans by careful mating, based on one’s genetic makeup. Negative eugenics, on the other hand, seeks to prevent those deemed inferior from reproducing, and thus not impeding man’s evolution.
