Second, we use archaeological radiocarbon dates to constrain the divergence time prior in our IM analyses to 15 kya as the latest possible date for both the divergence of the Amerind and Asian gene pools and the Amerind expansion into North America (Figure 3).
Both the divergence of the gymnosperms and angiosperms from the ferns, and that of the angiosperms from the gymnosperms involved whole genome duplication events [ 26].
Assuming our phylogenetic estimate is correct regarding the placement of the Mexican long-tailed rattlesnakes, this event happened subsequent to both the divergence of Sistrurus and the basal split within Crotalus.
The patterns of proteins coded in the Fusarium, Trichoderma, and Stachybotrys CTCs are consistent with both the divergence of the Stachybotrys CTC from that of Fusarium and the similar gene content of the Stachybotrys and Trichoderma CTCs, which share six genes.

Under one hypothesis, chromosome rearrangements accelerated in the teleost lineage after the TGD (Comai 2005; Semon and Wolfe 2007); alternatively, most rearrangements had already occurred in the human or ray-fin lineage or both before the divergence of gar and teleost lineages and are thus mostly independent of genome duplication (Hufton et al. 2008).
Although it is not clear how many spiggin genes occur in ninespine stickleback, this result suggests that the spiggin genes diverged both before and after the divergence of threespine and ninespine sticklebacks.
The compressibility of a dissipative particle dynamics (DPD) fluid is studied numerically through several newly developed test models, where both the density and the divergence of the velocity field are considered.
On the basis of whole-genome comparisons between two Deinococcus genomes and two Thermus genomes, we present a reconstruction of evolutionary events that are inferred to have occurred both before and after the divergence of the D. radiodurans and D. geothermalis lineages.
The regions, homologue to the two inversed fragments of non-rodent mammalians, are in opposite direction to those of mouse, which reveals both inversions occurred before the divergence of mouse and rat, and after the divergence of primates and rodents.
These facts and the results of our phylogenetic analysis imply that the ancestral spiggin gene existed as a single gene in the ancestral fish lineage, and duplications of the spiggin gene occurred both before and after the divergence of threespine and ninespine sticklebacks (Fig. 3).
The remaining 12 aaRS families have maintained distinct mitochondrial and cytosolic lineages both before and after the divergence of animals (fig. 2 A), resulting in a total of 15 specialized mt-aaRS genes that are inferred to have been present in the common ancestor of Metazoa.
