I made up stories in the matrix of the ancestral mode.
The formation of this derived mode of regulation did not disrupt the ancestral mode and thereby created a hybrid regulatory state where both means of transcription regulation (ancestral and derived) contribute to the conserved expression pattern of the network.
To do this we reconstructed the ancestral mode of transmission across our subtype phylogenies using "IDU", "non-IDU", and "unknown status" as character states.
In an alternative model [41] [5], it was argued that KAP-α-mediated transport was the ancestral mode, and that later KAP-α-independent pathways are a later simplification.
To estimate the ancestral mode of seed dispersal in myrmecochorous lineages, it was most parsimonious to assume that the dispersal mode in the non-myrmecochorous sister group was ancestral to both lineages.
Such equivocal results could indicate that the effect of seed dispersal mutualisms on diversification varies by either the ancestral mode of seed dispersal, biogeographic region, or the identity of the animal partner and the distance it moves seeds.
This also implies that the ancestral mode of SM-syntaxin interaction was through direct binding.
However, an alternative hypothesis is that Delta-Notch signaling is an ancestral mode of coupling cell oscillations during segmentation.
Furthermore the synthetases of class II (ancestral mode) amino-acylate the carbon 3', not the 2' as in my mechanism.
This mechanism of cell division may resemble an ancestral mode of division in the absence of cytokinetic machinery.
