Multicellularity is often considered a prerequisite for morphological complexity, as seen in the camera-type eyes found in several groups of animals.
If the bilateral symmetry exhibited in anthozoans is considered the ancestral cnidarian condition, a pattern emerges of increasing morphological complexity along the primary body axis at each phyletic divergence point leading to the last common ancestor of bilaterians.
Buick [3] discussed at what level of morphological complexity an object can be considered to be an undoubted microbial relic.
We found a significant main effect of morphological complexity, such that participants were significantly faster at reading the inflected matched control words (M = 568.43 ms) as compared with the inflected complex words (M = 603.33 ms), F (1, 47) = 20.41, p <.001.
I will present data from monosyllabic and polysyllabic words, as well as words of varying morphological complexity, to show that tone is culminative, both at the level of the morpheme and in the output, but not obligatory.
We found a significant main effect of morphological complexity, such that participants were significantly more accurate at reading the matched control words (M = 95.6%) as compared with the inflected complex words (M = 85.7%), F (1, 51) = 45.55, p <.001.
We found a significant main effect of morphological complexity such that participants were significantly more accurate at reading the pseudocomplex matched control words (M = 94.4%) than the morphologically complex words (M = 89.3%), F (1, 51) = 15.65, p <.001.
Based on the observations that intraspecific variation decrease through evolutionary time, that miRNA decrease stochastic expressional variation, and that miRNA numbers increase through evolutionary time and with morphological complexity, it has been suggested that miRNA are at the basis of the canalization development required for increased organismal complexity [ 21].
At symptomatic ages, we find reduced morphological complexity in the neuromuscular junction.
Furthermore, this finding suggests the increase in morphological complexity of the sporophyte body in the Paleozoic resulted at least in part from the recruitment of regulatory genes from gametophyte to sporophyte.
