Writing in the mid-1960s with A.W.F. Edwards, another genetics student of Ronald A. Fisher, Cavalli-Sforza pioneered statistical methods for estimating evolutionary trees (phylogenies).Cavalli-Sforza, L., Edwards, A. W. F. (1967). Phylogenetic analysis: models and estimation procedures. American Journal of Human Genetics 19: 233–257 Edwards and Cavalli-Sforza wrote about trees of populations within the human species, where genetic differences are affected both by treelike patterns of historical separation of populations and by spread of genes among populations by migration and admixture. Many of these influential and fundamental early papers were reprinted in 2018 in a volume focusing on A. W. F. Edwards, and dedicated to Cavalli-Sforza and Ian Hacking. In later papers, Cavalli-Sforza has written about the effects of both divergence and migration on human gene frequencies.
