Where in the book "Origin of Species" does it say that we should kill Jews?
survival of the fittest was carried out into social darwinism, where this was somehow made okay. But it started with survival of the fittest.
the University of Colorado at boulder (database)
states that among social darwinists is the survival of the fittest mentality:
"most propose arguments that justify imbalances of power between individuals, races, and nations because they consider some people more fit to survive than others."

STAN STATE history professor agrees:
"I will highlight the ways that Nazi racial
thought was shaped by Darwinism (defined as biological evolution through the process
of natural selection). First, almost all Nazi racial theorists believed that humans
had evolved from primates. Second, they provided evolutionary explanations for the
development of different human races, including the Nordic or Aryan race (these two
terms were used synonymously). Specifically, they believed that the Nordic race had
become superior because harsh climatic conditions in north-central Europe during
the Ice Ages had sharpened the struggle for existence, causing the weak to perish and
leaving only the most vigorous. Third, they believed that the differential evolutionary
development of the races provided scientific evidence for racial inequality. Fourth,
they held that the different and unequal human races were locked in an ineluctable
struggle for existence. Fifth, they thought that the way for their own race to triumph
in the struggle for existence was to procreate more prolifically than competing races
and to gain more “living space” (Lebensraum) into which to expand. Sixth, many
argued that Darwinism promoted a collectivist ideal. These six points—derived from
the view that humans and human races evolved and are still evolving through the
Darwinian mechanism of natural selection—profoundly impacted Nazi policy. They
formed the backdrop for eugenics, killing the disabled, the quest for “living space,”
and racial extermination.9"
