The theory of recapitulation, also calle the biogenetic law or embryological parallelism, and often expressed as ontogeny recapitulates phylogeny, was first put forward in 1866 by German zoologist Ernst Haeckel. Haeckel proposed that the embryonal development of an individual organism (its ontogeny) followed the same path as the evolutionary history of its species (its phylogeny). This theory, in the highly elaborate and deterministic form advanced by Haeckel, has, since the early twentieth century, been refuted on many fronts. Haeckel's drawings used artistic licence, his theory was associated with Lamarckism, it was quite clearly wrong in supposing that embryos passed through the adult stages of more primitive life-forms, it ignored organs such as teeth which are "held over" to a late developmental stage, and it was used by Haeckel to promote the supremacy of the white European male. However, the basic idea of recapitulation is still potent enough to have been the subject of Stephen Jay Gould's first book, and that book begins by declaring that many medical professionals still believe, privately and informally, that there is "something in" the notion: the parallels between ontogeny and phylogeny are still one of the great themes of evolutionary biology.
