However, the problem of how the fluid necessary for ocular dimensional changes is accumulated or dispersed is only addressed by our theory of RPE/Müller cell controlled ionically driven trans-retinal fluid flow between vitreous chamber and the choroidal lymphatics [6].
Recently, however, evidence pointing to objective changes is accumulating [ 31].
Genes with dN/dS > 1 are formally defined as being subject to positive selection, in fact amino acid changes are accumulating faster than would be expected given the underlying silent substitution rate.
While no comprehensive theory of time until pseudogenization exists, one may expect that selection in favour of complete loss of expression or complete loss of a pseudogene altogether is weak and degenerative changes are accumulating by drift, thus allowing slow and gradual decay.
It comes from the fact – if you say, where is that result coming from – it comes from the fact, if you start at some point and you go to another point and you ask for the change in the function, the change is accumulating as you move.
Overall, the volume highlights that, although data on the evolutionary potential of populations in response to climate change are accumulating, we are still far from where we hope to be in terms of predictive ability, especially given the complexity of most environments (Merilä and Hendry 2014).
Small, incremental improvements could be passed from generation to generation and changes could be accumulated, leaving the starting point far behind.
In esophageal cancer, information about cancer-associated epigenetic changes has been accumulated mainly through research on Barret esophagus and esophageal adenocarcinoma.
In patients who received tamoxifen, inhibiting such regulation, or indeed the acquired genetic and epigenetic changes that are accumulated by residual breast cancer cells, could then positively select for a more aggressive cell phenotype, as previously suggested in experimental models [ 3, 13].
The low slopes (0.00 0.02) of transitions at mitochondrial third codon positions and 16S loops indicated these were accumulating changes independently from shared evolutionary history (Table 2).
