Prior to Charles Darwin, there were many scientists who claimed that a species is evolved from another species or ancestor. However, in those times there were no scientific evidence to prove the concept of evolution.

Like Cope, Huxley proposed an evolutionary relationship between birds and dinosaurs. Although Huxley was opposed by the very influential Owen, his conclusions were accepted by many biologists, including Baron Franz Nopcsa, while others, notably Harry Seeley, argued that the similarities were due to convergent evolution .

Dinosaurs, Huxley proposed, could not have been ancestral to birds, but they did represent the form of those ancestors. Huxley formally presented his ideas to his colleagues the same year that he wrote Haeckel, but his work on the subject was only just beginning.
