Ontogeny and Phylogeny ... If you observe a chick’s development, you will find that the chick embryo may resemble the embryos of reptiles and fish at points in its development, but it doesn’t recapitulate the forms of its adult ancestors.

In other words, the features that distinguish between different species tend to arise late in development; ... It turns out that for some characterstics the ontogeny of the trait does go through stages much like the adult forms of the ancestors of the species with the trait-- that is, ontogeny does recapitulate phylogeny.

Response: I'll get to my own approaches later on, but for now, let me start by looking at the historical roots of these approaches to dosing, as, afterall, ontogeny does tend to recapitulate phylogeny ...

Whilst the theory proposed by Haeckel has been rejected, there remains some grounding to the observation that more evolutionarily derived traits often tend to occur later in embryological development.
