Coghill performed much of the empirical work supporting the theory that development of movement is not simply the accumulation of individualized reflexes, but rather a result of the differentiation of generalized total movement.

and limb movements in reptiles and opossums. Though he wasn't able to finish the experiments with these animals, Coghill was anticipating that the differential fin and limb movement developed in a similar fashion as the
Ambystoma. At the time of his death, Coghill was also working on a manuscript
194:; the movement of a specific limb involves the inhibition of activity of the rest of the body and, thus, the movement of a particular limb requires excitation of one part of the body and inhibition of the rest of the body. This behavior was only descriptive towards species-specific

embryos. These movements developed over time from unspecific, sometimes spontaneous, myogenic motions to unilateral flexures to concerted motions that resembled swimming. Coghill hypothesized that this movement was the precursor to later feeding behavior or walking behavior.
