Huxley's first 'trial run' was the treatment of evolution in the Science of Life (1929-30), and in 1936 he published a long and significant paper for the British Association [REF].
Huxley's main co-respondents in the modern evolutionary synthesis are usually listed as Ernst Mayr, Theodosius Dobzhansky, George Gaylord Simpson, Bernhard Rensch, Ledyard Stebbins and the population geneticists J. B. S. Haldane, Ronald Fisher and Sewall Wright.
