Conversation so far:
What is the empirical test of pangenesis and Lamarckism?
Galton explicitly rejected the idea of the inheritance of acquired characteristics (Lamarckism).
Did he develop the empirical test?
he transfused the blood between dissimilar breeds of rabbits, and examined the features of their offspring.
What was he hoping to prove by doing this?
He found no evidence of characters transmitted in the transfused blood.
Did he consider this test a failure?
Darwin challenged the validity of Galton's experiment, giving his reasons in an article published in Nature.
Did Galton ever respond when Darwin questioned the validity of his experiment?
CANNOTANSWER.
What year did he conduct the experiment?
1869 to 1871.
Were the results published in any journal or scientific publication?
He went on to found the biometric approach to the study of heredity, distinguished by its use of statistical techniques to study continuous traits and population-scale aspects of heredity.

Question: Did his studies in these areas help advance any scientific fields?
Self-contained rewrite: Did Francis Galton studies in heredity help advance any other scientific fields?
