Consonant repetition ("reduplication") predominates in #CVC sequences in babbling and early words, gradually giving way to consonant variation ("variegation") with a "Fronting" pattern whereby the first consonant has a more anterior place of articulation than the second. The various reduplicative patterns are primarily attributed to a "Frame" consisting of rhythmic mandibular oscillation. Evidence, including new evidence from a case study, suggests a labial-coronal-dorsal hierarchy of consonant production difficulty. Fronting may therefore result from a tendency to begin variegated sequences with an easier consonant and continue with a more difficult one. Easier initiation may be a self organizing response to the functional load involved in interfacing the lexicon with the motor system. The heavy favoring of one particular variegated sequence, the labial-coronal sequence, in both infants and languages, suggests that it may have been a first discrete step towards increasing serial output complexity in phylogeny just as it is in ontogeny.
