The phrase "an evolutionary gain" is correct and usable in written English.
It can be used in contexts discussing biological or evolutionary advantages that an organism or species may acquire over time.
Example: "The development of camouflage in certain species is considered an evolutionary gain that enhances their survival in the wild."
Alternatives: "an evolutionary advantage" or "a biological benefit".
Selection coefficient is different from selection intensity, a term used mainly in breeding and quantitative genetics to quantify a potential evolutionary gain after selecting a pool of parents from a variable population.
Building upon these prior findings, we explored undergraduate biology majors' reasoning about the role of "pressure" in evolutionary explanations using a newly developed and validated set of open response items in both evolutionary gain and loss contexts (see Table 1).
We have also identified two evolutionary "gain" traits: derived freshwater fish have evolved more pharyngeal teeth and bigger branchial bones (Cleves et al., 2014; Erickson et al., 2014; Ellis et al., 2015).
Post-instruction, the majority of biology majors who employed force-talk in evolutionary gain and loss scenarios displayed faulty models of evolutionary causation.
Within the context of evolutionary gain, such as the gain of acorns in oak species, 21.5% of students used pressure in their responses.
Our student response data therefore consist of (1) initial and (2) follow-up responses about pressure-related text among evolutionary gain and loss scenarios.
The weak relationship between presence of leaf teeth and temperature after accounting for phylogeny indicates that the prevailing adaptive scenario since 1915 [1], whereby temperature is the primary force explaining evolutionary gain or loss of leaf teeth, is inaccurate.
The small, but non-zero, slope of the phylogenetic regression suggests that temperature is at most only weakly related to the evolutionary gain and loss of teeth, and thus the proportion of toothed species in a flora at a given temperature would not be expected to be constant through time.
The method identifies independent instances of the evolutionary gain or loss of pairs of proteins.
