In the new report, the researchers use computational simulations to date the spread of H. pylori out of Africa to about 58,000 years ago, which supports a more recent migration out of Africa.
In contrast, an analysis of diverging conspecific populations or 'phylogroups', which were interpreted as reflecting incipient speciation, supported a more recent time-scale for avian diversification [35].
Actually, it is worse than that – even with large values of M and S, where most of the data supports a more recent divergence, the high sequence similarity allows a wide range in the genes divergence times, wide enough so that they can be spaced to match the times expected from that species divergence time with no migrations.
Since all inferences of demographic histories were based in one or the other way on mutation spectre in observed data, it is not possible, in our opinion, to detect expansion times older than the data themselves, supporting a more recent expansion of benthic species.
A scenario in which Nomascus diverged first, followed by Symphalangus, Hoolock and then Hylobates is well-supported by analyses of mtDNA control region segments [6], and is also inferred, albeit with weaker statistical support, in a more recent study of mtDNA cytochrome b (cyt b) sequences [4].
Support for a more recent colonization of Mesoamerica by primary freshwater fish through the Panama Strait comes from phylogeographical studies of Characids (e.g., Brycon, Bryconamericus, Eretmobrycon, and Cyphocharax).
Our finding that peers and parents encouraged female students was also supported by a more recent study in Israel (Gabay-Egozi et al. 2014).
This cut-point related finding is supported by a more recent study [ 46].
This finding was supported in a more recent Turkish study (Altundag et al, 2000).
These data are supported by a more recent study from Korea (Kim, et al., 2012b).
