Charles Darwin remains a controversial individual...
Charles Darwin remains a controversial individual because of his theory of evolution. Little known to the public is his cousin Francis Galton, who made an equally revolutionary discovery in the evolution of a species, but absent of Darwin's controversy. Galton became intrigued with the nature of heredity. He developed mathematical formulas to examine the relative contributions of both parents, as well as grandparents, to the inherited makeup of an individual. He recorded how certain traits were passed on from one generation to another.
