Such postsynaptic models are unparsimonious, and so if any given starburst amacrine cells conveys motion information to retinal ganglion cells then any computing of'local'direction selectivity postsynaptically by retinal ganglion cells is redundant and dysfunctional.
2.
However, homoplasy is often not evident from inspection of the character itself ( as in DNA sequence, for example ), and is then detected by its incongruence ( unparsimonious distribution ) on a most-parsimonious cladogram.
