Another book links Darwin to Hitler
One reviewer of "The Nazi Connection" noted that the son of Charles Darwin attended a meeting of the eugenics movement:
Kühl explores the international nature of the eugenics movement, beginning with the first international meeting organised by the International Society for Racial Hygiene in Dresden in 1911. The meeting drew people from all over Europe and the United States. A further meeting the following year included the son of Charles Darwin and Winston Churchill as representatives -- the latter being the Home Secretary at the time.
Other reviews of the book are here and here.
Also, it has been claimed that the opposition of William Jennings Bryan -- the politician who was the prosecutor at the 1925 Scopes "monkey" trial -- to Darwinism was motivated by his opposition to Social Darwinism -- see this and this
So it seems that this idea of Darwin-to-Hitler is hardly new, which makes it surprising that the recent TV show on this subject sparked such shock and outrage.
