 and extant species should exhibit relationships. His work charted the evolution from the early fishes through the various branches to birds and mammals, with numerous papers and two major works: Our Face from Fish to Man in 1929 and Evolution Emerging in 1951.

He developed the principle of habitus and heritage — theorizing that animals evolved with two sets of characteristics: the heritage features which derived from a long evolutionary history and the habitus characteristics which were adaptations to the environment in which the species existed. He later expanded this to his palimpsest
Palimpsest
A palimpsest is a manuscript page from a scroll or book from which the text has been scraped off and which can be used again. The word "palimpsest" comes through Latin palimpsēstus from Ancient Greek παλίμψηστος originally compounded from πάλιν and ψάω literally meaning “scraped...

s and early reptiles. Around the early 1920s he also became interested in recent human evolution particularly after the discovery of the early African hominids. His specialist knowledge of mammalian dentition led him to pursue the same path with regard to human evolution and he came to be regarded as the world's leading expert on the evolution of human dentition, a reputation secured by the 1922 publication of The Evolution of the Human Dentition.
