In addition to his international and humanist concerns, his research interests covered evolution in all its aspects, ethology, embryology, genetics, anthropology and to some extent the infant field of cell biology. Julian's eminence as an advocate for evolution, and especially his contribution to the modern evolutionary synthesis, led to his awards of the Darwin Medal of the Royal Society in 1956, and the Darwin–Wallace Medal of the Linnaean Society in 1958. 1958 was the centenary anniversary of the joint presentation On the tendency of species to form varieties; and the perpetuation of varieties and species by natural means of selection by Darwin and Wallace.Bowler, Peter J. 2003.
