As such, this study demonstrates cross-species validity of multiple cellular phenotypes associated with loss of FMRP between two mammalian species that separated in evolution more than 12 million years ago (12).
(The arguments we mentioned in the preceding paragraph and in 2.4.1 would have deeper implications if correct, for they easily imply challenges to all characterizations in terms of species of validity as well).
In some of these cases, this attitude is explained by a distrust of notions that are thought not to have reached a fully respectable scientific status, like the strong modal notions; it is frequently accompanied in such authors, who are often practicing logicians, by the proposal to characterize logical truth as a species of validity (in the sense of 2.3 below).
Although it is likely that observations made in the mouse β-globin gene domain are also relevant for this locus in other species, the validity of this supposition still lacks direct experimental evidence.
In the context of translational drug discovery, it may therefore be likely that effects of putative cognitive enhancers observed in the 5C-CPT would exhibit substantial cross-species predictive validity for effects in the human CPTs.
These results, initially obtained with pine, have been extended to different softwood and hardwood species to check validity of the method using equipment specially designed to measure mass losses during thermal treatment.
However, molecular analysis determined that Snyder's type collection contained two distinct species, rendering the validity of the taxon dubious.
intestinalis sp.A sp.B) and morphologically very similar (Botrylloides leachii– Botrylloides nigrum) species add further validity to our data set, because they permit a more straightforward interpretation of the identified substitution rate differences.
These varied considerably in their predictive power and validity between species.
They also recognised the validity of species such as P. lipidus, P. tienshanensis, and P. sui.
