Ontogeny used in a sentence

Ontogeny in a sentence as a noun

Is "feeling guilt" a learned skill, or does its ontogeny happen "all on its own"?

Birds' intelligence is especially interesting because the ontogeny differs from that of primates and other mammals like the dolphins.

For example, few GAs implement anything resembling ontogeny or lifetime learning, and generally have a poor genotype/phenotype divide.

It's probably as attractive and simplistic as the old saw "ontogeny recapitulates phylogeny".

This doesn't really sound like a completely new theory; Haeckel proposed in the 1800s that "ontogeny recapitulates phylogeny", and it is widely understood that cancer is like a de-differentiated state.

If one understands drawing in this way, it does not record an independent process of development, rather it documents and reflects its own developmental conditions—and thereby furthers mental ontogeny.

The original formulation was “ontogeny recapitulates phylogeny” and Stephen Jay Gould has written a book on the history of the idea, so I'm not sure if the revision is intentional or due to sloppiness.
