: Is "ontogeny recapitulates phylogeny" the precise phrase? If so, what exactly does it mean? Who conined the phrase? And is it still taught as a correct principle in biology?

: : : : : Ahem

: : : : Meaning something like 'birds of a feather flock together' is it?

: : : No, not that. It means that an individual goes through a succession of stages in its development that resembles the stages of development that its species went through when evolving. For example, human fetuses at one (early) stage of development have gills.

: : : I don't know who coined the phrase or whether the principle is still thought to be correct.

: : R.Berg's explanation is correct. The concept, however, is wrong, although it still appears in many textbooks even today. The German biologist Ernst Haeckel coined the phrase (as well as the word 'phylogeny') near the end of the 19th C. For more information, see'll find more by googling on the phrase, or on Haeckel's name; but be aware that 75% of what you'll find online is total BS; look for sites sponsored by univerities.

: When googling use 'site:edu' as one of the required search phrases to get mostly universities and fewer BS hits.

: : : Looks like I'm a little late for the main discussion of this topic but I have a burning question: If Creationists are correct, that Ernst Haeckel's theory is BS, what explains my personal nursing experience of having cared for little newborns who exhibited gills and, yes, even little Henry who had gills, a significant tail and other birth "anomalies"? I am just asking for information here; I do not, as apparently others in the discussion have, underlying religious issues to deny or confirm.

I am a Bible-thumping fundamentalist who believes that Genesis describes how God created the World and, through evolution, its creatures. Have I created a new theory? I need a name for it.
