Alternatively, we conduct alternative hypothesis testing regarding the population distribution by the likelihood ratio test (Clauset et al., 2009), which suggests that the distribution is a power-law if the likelihood ratio between the alternative and power-law distribution is positive.
Alternatively, the hypothesis that these new TE families may originate from HTs not already characterized cannot be completely excluded.
Alternatively, the hypothesis that folding of the soluble domains of AdcA and of AdcAR491A are different enough from that of AdcA to decrease the affinity for the kinase would perfectly accommodate a soluble kinase.
However, more data would be required to test this interplay between shifts of global circulation patterns and reassortment, or, alternatively, the hypothesis that global continuous circulation prevents the emergence of highly pathogenic strains by eliminating chance reseeding.
Alternatively, structural hypotheses propose that eggshell colour evolved to enhance the physical protection of the developing embryo.
Alternatively, the hypothesis-free identification of genes from in silico approaches (e.g. [ 169]), or the detection of aberrant (behavioral) phenotypes in systematic screens (e.g. ENU-mutagenesis approaches: [ 96, 170- 178]) and confirmation of these phenotypes as inherited may serve as starting point of model building.
For example, if a Canadian study of second wave pH1N1 infections found no apparent risk due to seasonal vaccination then that gives some additional weight to the temporary immunity hypothesis, alternatively if a similar apparent risk is found then an alternative mechanism is more likely to be involved.
Alternatively, the selection hypothesis states that intermarried immigrants are positively selected into the labor and marriage market.
Alternatively, the untested hypothesis that thermal variance itself induces differential fitness, or is correlated with such a variable [50], and therefore underlies the evolution or maintenance of TSD [15], should be considered.
Alternatively, and the hypothesis we subscribe to, it may be that an entire night of sleep contains multiple sleep-stage windows preferentially devoted to the consolidation of many different forms of daytime learning [29].
