The phrase "a signal of evolution" is correct and usable in written English.
It can be used to indicate a sign or indication that evolution is occurring or has occurred in a particular context.
Example: "The discovery of new fossil records serves as a signal of evolution in the species over millions of years."
Alternatives: "an indication of evolution" or "a sign of evolutionary change".
Because higher ω in Cercopithecinae can be taken as a signal of neutral evolution we simulated neutral evolution using ReEVOLVER 1.0 [30] and found that it is very unlikely to observe no disrupting mutations in Cercopithecinae TAAR4 orthologs (Pdis = 0.0006) within 55 myr of neutral evolution (or 7.2 synonymous substitutions, respectively).
First, the indoor aquarium experiment showed that the evolutionary response to thermal selection may strongly depend on population dynamics: only in the treatment where recurrent periods of exponential growth were possible, a signal of thermal evolution was recovered (Van Doorslaer et al. 2009a).
We then tested for the existence of a signal of adaptive sequence evolution in the coding region of csf1ra.
If we reinvent the TOL as a signal of partially congruent evolution of individual genes and try to measure this trend quantitatively, the answer comes out as ~40% tree-like evolution [ 16].
Such a signal of adaptive sequence evolution specific to the haplochromine lineage could not be detected in a segment of the extracellular domain of kita, another type III receptor tyrosine kinase with a known function in pigment patterning [ 31], which we have sequenced in the 19 cichlid species as a control.
If data present a signal of non-homogeneous and non-reversible evolution in time (such as drifting GC content through evolution), it might be possible to infer the position of the root using non-reversible models.
In Figure 1, we show vials with reacting samples for different AgNO3 concentrations (0, 2.5, 5, 7.5, 10, and 15 mM), and different times after the reaction started (24, 48, 72, and 96 h); the clear time evolution is a signal of the growth of silver nanoparticles.
Under the one instance where PST < FST in inland no predator PCI, the h/ c ratio was low at 0.283 and we may conclude that Q ST < F ST, i.e. a signal of convergent evolution/stabilizing selection on spine length in inland populations without predators.
Among the different host-specific lineages, we also detected a weak signal of reticulate evolution.
Within D. ananassae, a significant signal of adaptive evolution is also detected for female-biased and unbiased genes.
