In biologically plausible instances of this scheme, this derivative would have to be computed on the basis of a mapping from action to sensory consequences.
Author's response: In the first paragraph of the paper, we cite several plausible instances of parallel evolution that is driven by positive selection.
Prior to the present study, at least two plausible instances of horizontal transfer implicating snake TEs have been reported, involving Bov-B LINEs (Kordis and Gubensek 1998b) and Sauria SINEs (Piskurek and Okada 2007).
It was never plausible, for instance, to expect that NAFTA would be a net creator of jobs.
It's plausible, for instance, that Mr. Romney's opposition to the auto bailout will be more of a disadvantage in Ohio than in Pennsylvania, since the former state relies more on auto industry jobs.
However, there are certain specific examples where radical conceptual reorganization is plausible, for instance, when children eventually develop a theory of matter that allows them to differentiate weight from density, and air from nothing (Carey 2009).
In some situations they seem plausible: for instance, the plight of some stateless national groups — the history of Jews and Armenians, the historical and contemporary misfortunes of Kurds — lends credence to the idea that having their own state would have solved the worst problems.
As for (1), it is plausible, for instance, that subsequent studies will allow defining GIT "enzymotypes".
However, existence of multiple causal variants in tight linkage is plausible, for instance if any of several mutations within a single gene, or combinations of those mutations, alter disease susceptibility.
This hypothetical situation is quite plausible; for instance, catabolite repression is a widespread regulatory process by which bacteria shut down operons responsible for metabolizing lower-quality sugars when a better quality sugar is available.
