1. Eugenics
Eugenics, the selection of desired heritable
characteristics in order to improve future generations,
typically in reference to humans. The
term eugenics was coined in 1883 by British explorer
and natural scientist Francis Galton, who, influenced
by Charles Darwin’s theory of natural selection,
advocated a system that would allow “the more
suitable races or strains of blood a better chance of
prevailing speedily over the less suitable.” Social
Darwinism, the popular theory in the late 19th
century that life for humans in society was ruled by
“survival of the fittest,”

2. the study of
or belief in the possibility of improving the qualiti
es of the human species or
a humanpopulation, especially by such means as
discouraging reproduction by persons having gen
etic defects orpresumed to have inheritable unde
sirable traits (negative eugenics) or encouraging
reproduction bypersons presumed to have inheri
table desirable traits (positive eugenics).

3. Euthenic
• Euthenics is a branch of applied genetics
under which are studied the methods of
providing, the best environmental conditions
to ‘nurture’ to ensure complete expression of
all eugenic traits in the developing children.
Euthenics recommends the following methods
to ensure maximum expression of genes of
superior traits in the children.

4. 1. Selection of Children with Superior
Traits
• The primary requirement in euthenics is to
select children having genes of superior traits.
An effective way to do this is to put the
children on intelligence tests through
questions based upon the capabilities of
thinking, memory, logic and debate, self-
control, etc. Following two methods have
been employed in psychobiology to test the
intelligence of an individual.
