However, the RSCA was designed for use with children and adolescents and as such does not include items reflecting the developmental complexity of young adults.
Surprisingly, the gene numbers did not correlate well with the developmental complexity, growth habit, or even evolutionary distance between species.
The developmental complexity of sensory neuron specification has been extensively analyzed (Lallemend and Ernfors, 2012), but the links to function remain obscure.
The duplication of pre-existing genes had profound evolutionary implications for the developmental complexity in vertebrates, since mutations modifying the function of a duplicated protein can lead to novel functions, improving the evolutionary success.
The extraordinary virtuosity of streptomycetes as producers of secondary metabolites, including most of the antibiotics and anti-cancer agents in wide use, is associated with the developmental complexity of Streptomyces colonies, which have a vegetative substrate mycelium and a spore-bearing aerial mycelium.
These molecular data underscore the unique developmental complexity of spermiogenesis.
Gene duplication can be a source of innovation for the increased developmental complexity of plants.
On the other hand, given the morphological and developmental complexity of the rostellum [ 47, 48, 105], it is not unexpected that we find no evidence for the regain of this organ.
The understanding of developmental complexity will, therefore, require the characterization of protein interactions within their proper environment.
Since the protein-coding repertoire (notwithstanding some clade-specific innovations) has remained relatively static, the differences in developmental complexity must be due to an expansion of the accompanying regulatory architecture, which presumably lies outside the protein-coding sequences.
