We explicitly test that assumption here.
However, we were unwilling to assume monophyly of extinct clades that were not explicitly tested in our phylogenetic analyses.
The adaptive argument for phenotypic divergence was never explicitly tested against a null, nonadaptive explanation that could account for the differences between invasive populations.
Importantly, this model of higher rates of adaptation at X-linked regions in close proximity to genes in derived populations makes several predictions that can be explicitly tested in the future.
We explicitly tested for contributions to fitness that, if acquired by one subpopulation would affect the others, such as uptake and resistance to starvation.
Thus, we explicitly tested whether competition could induce evolutionary divergence by directly reversing the changes that occurred during competitive release.
However, this effect supposedly affected primarily the items that were used at the test of learning since only those items were explicitly tested in a forward direction.
In Experiment 2 we explicitly tested the proposition that behavioral tasks that require the rapid encoding of spatial information are particularly sensitive to the effects of MTT transection.
A report by the British Academy of Medical Sciences (14) highlighted the need to question and explicitly test assumptions that observed associations are causal, before findings can be used to inform prevention and intervention strategies.
To date this is the only experiment that explicitly tested the hypothesis that energetic constraints affect biparental incubation-scheduling.
