Plasticity and constraints in development and evolution

Abstract: Morphological similarities between organisms may be due to either homology or homoplasy. Homologous structures arise by common descent from an ancestral form, whereas homoplasious structures are independently derived in the respective lineages. The finding that similar ontogenetic mechanisms underlie the production of the similar structures in both lineages is not sufficient evidence of homology, as such similarities may also be due to parallel evolution. Parallelisms are a class of homoplasy in which the two … Show more

“…However, developmental and physiological differences between insect and human eyes are enormous, suggesting differential recruitment of downstream programs of eye formation in each lineage under the same master regulators (Pichaud et al, 2001;Nilsson, 2004). Such genetic conservation of master regulation is explained as a result of evolutionary constraints of regulatory circuits for cuing some developmental processes (Hodin, 2000). Identifying where genetic differences occur in each eye development pathway will shed light on understanding the developmental differences arising during evolution.…”

“…Rather, it shows that the pathway, or pathways, to hyperphalangy found outside of mammals are rarely followed within the mammals. Thus, as has been argued, parallelism (independent evolution using the same mechanism) can be evidence of developmental constraint (Wake, '91;Hodin, 2000).…”

“…Developmental canalization (Waddington's epigenetic landscape) and plasticity correspond to the developmental route towards regulating change (Jablonka and Lamb 2002, 85). While the former decouples phenotypic and genetic change in explaining dynamic stabilization, the latter is invoked in the explanations of biological innovation, that is, the convergence of different developmental pathways on similar solutions (Hodin 2000). There is a counter view of convergent change as the outcome of phylogenetic constraints that drive different 14 biological solutions towards similar ends, given the shared problem of adaptation to a limited set of environments and ecological niches (Moore and Willmer 1997, 12).…”
