From this point onwards, I will do only the exercises that add to the code base I've written for the rest of the chapter. Time to get back on track! Let's finish up Chapter 4. I sure fell off the Sokal and Rohlf horse.

Along with Luca Cavalli-Sforza, Sokal pioneered the comparative study of linguistic and genetic variation. His interests shifted to anthropology and population genetics, and he directed studies on the population history of Europe as inferred from genetic and ethnohistorical data. James Rohlf, Sokal worked on new statistical methods for the analysis of geographic variation. At the State University of New York, Stony Brook, in collaboration with F. In 1959, Sokal moved to the University of Kansas where he developed-initially in collaboration with Charles Duncan Michener-quantitative techniques for classifying organisms and building dendrograms, which later came to be called numerical taxonomy methods.
Sokal developed an interest for statistics and quantitative biology. He was also strongly influenced by Sewall Wright, who served on his dissertation committee. degree under the supervision of the well-known termite systematist Alfred E. John's College in Shanghai and from there moved with his wife Julie to the University of Chicago, where he also worked as a librarian to complement his scholarship. In 1939, following the annexation of Austria by Nazi Germany, he escaped with his family to China. Robert Sokal was born in 1926 in a Jewish family in Vienna, Austria.
