Following passage, there was an inherent culture-based selection for fibroblasts based on cell morphology and lineage-marker expressions.
In terms of style shape, the two most divergent species, C. catalinensis and C. ericsmithi, provide insight into the possible relationship between style and rattle matrix morphology and lineage-specific evolutionary strategies for retaining rattle segments.
Further examples of correlation between jaw morphology and a lineage's position in δN/δC assemblage isotope space can be seen among the non-wood-eating Ancistrini and Loricariini.
However, we detected a discrepancy between the mitochondrial lineage and, the morphology and the nuclear lineage of two specimens of form R, one from the Meuse and one from the Seine, two of the three rivers where we found forms R and S in sympatry.
He suggested that in "an extremely remote period" (p. 125) animals with these morphologies produced one lineage leading to vertebrates and another lineage "retrograding in development" (p. 125) to become today's tunicates (Darwin 1871).
As this is happening, embryos still retain blastocyst morphology and all cell lineages are polarized.
In other words, two lineages have evolved convergently if they started from different ancestral morphologies and evolved towards the same (adaptive) phenotype (Fig. 3a).
Colony data analysis was performed in Mathematica, with customized functions developed to determine species abundance, colony morphology, cell lineages, and segregated sectors.
In addition to the metrics used to quantify the spatial structures of the expanding colonies (i.e. relative abundance, morphology, surviving lineages, and colony sectors), we have also considered the time evolution of the cell density.
BO-1 cells displayed a bi- to multipolar morphology and expressed early oligodendrocytic lineage markers, such as A2B5 and NG-2.
