Based on synonymous substitution plots of gene duplication events, a whole-genome duplication in P. patens has been hypothesized and dated to ~45 MYA [ 23].
We hypothesized, that among date-hubs and party-hubs of similar centrality, date-hubs may have a higher bridgeness (i.e. they are more overlapping between modules of the network).
If Agamidae did migrate to Eurasia on India as hypothesized above, the dating result suggests that subfamilial radiations of agamids occurred on the drifting Indian subcontinent.
Although an effect of carotenoids on non-visual (e.g. acoustic) signals involved in sexual selection has been hypothesized, this has to date not been investigated.
It has even been hypothesized that Pycnogonida might date back to the Cambrian [ 30].
Because a single dose of the human IgM rHIgM12 preserved neurological deficits in a virus-mediated model of spinal cord demyelination and the IgM bound to the surface of every neuronal type in cultures tested to date, we hypothesized that rHIgM12 might be protective across neuronal disease injury models.
As molecular dating depends upon accuracy of rate modelling, inferred rate variation within long branches has been hypothesized to contribute to dating error, e.g. in the crown node of angiosperms [ 4].
"This careful piece of work should settle the debate because it shows that indeed there is some mobility of lead, which was hypothesized to result in dates that were too old, but the scale of mobility is nanometers," said Samuel Bowring, a geochemist at MIT, who was not involved in the study.
At each site the scientists looked at, the diamond layer in the rocks correlates to the date of the hypothesized impact.
With respect to laying date, it was hypothesized before that if one sex requires a longer maturation period than the other, it should have an advantage when born early in the year, and mothers should anticipate this by producing the slowly maturing sex when breeding early and the faster maturing sex when breeding late (Dijkstra et al. 1990).
Finally, the young TMRCA (3.5 ka; 95% CI: 1.7 5.9 ka) for the node separating the sequenced (former) E-M35* and E-M293 samples suggests a TMRCA for the M293 variant more recent than previously hypothesized using an STR-based dating (11.4 ka; Henn et al. [2008]).
