Furthermore, larger-brained species reach their adult skill levels later than smaller-brained ones, largely because they start later with the simplest techniques.

In current scientific parlance, then, “ontogeny recapitulates phylogeny” means that many developments take place during ontogeny in roughly the same order that they took place in during phylogeny.
WebThe single cell corresponded to amoeba-like ancestors, developing eventually into a sea squirt, a fish, and so on. Haeckel, who was adept at packaging and promoting his ideas, coined both a name for the process — “the Biogenetic Law” — as well as a catchy motto: “Ontogeny recapitulates phylogeny.” WebThis type of reasoning, of course, is specious, at best, and so is that which justifies racism, or Freudianism, or even the standard evolutionary interpretation of the fossil record. As we have shown, all these concepts have been largely based on the discredited quasi-scientific notion of the 19th century that "ontogeny recapitulates phylogeny."

Haeckel that people during their embryonic development pass through stages similar in general structural plan to the stages their species passed through in its evolution; more technically phrased, the theory that ontogeny is an abbreviated recapitulation of phylogeny.

WebHence, Ernst Haeckel's dictum “ontogeny recapitulates phylogeny.” The reason for this dictum appears to be the immortality of genes.
