Figure 1 The Evolution of Man This cartoon by Edward Linley Sambourne, published in Punch in 1882, was a parody of Darwin's ideas on the origins of man. Although presumably unaware of Dohrn's 1875 ideas of axis inversion, the artist has aptly depicted the evolution of vertebrates from an annelid worm-like ancestor. One can even imagine that the worm at the bottom left is captured in the process of inverting its dorsoventral axis.
