The fossil record indicates that the sections of Cycas have been diverged for 30 million years, making such a scenario unlikely [ 10].
After comparing the mitochondrial noncoding sequences of two Arabidopsis thaliana ecotypes that had been diverged for approximately 200,000 years, I proposed that coding and noncoding DNAs are repaired by different mechanisms and thus have different mutation rates and spectra (Christensen 2013).
The comparison of the two divergent Rosaceae species groups that have been diverging for a minimum of 32 million years [ 42] may shed light on which issues are likely to be general.
Knowing that D. americana and D. virilis have been diverging for 4.1 Myr (Morales-Hojas et al. 2011), that the average divergence and polymorphism for these chromosomes is 5.8%and1.2%2%, respectively, and under the assumption of eight generations a year (discussed earlier), an effective population size of approximately 3.5 million individuals can be estimated.
The Welsh and English social work landscapes have been diverging for some years.
The twins still saw each other frequently, but their lives were diverging for the first time.
In the UK in 2012 the line between personal life and work life is diverging for many people, not integrating.
Gheg and Tosk have been diverging for at least a millennium, and their less extreme forms are mutually intelligible.
For CG7676 gene this value has been extrapolated under the assumption of a molecular clock and that D. melanogaster and D. virilis have been diverging for about 40 million years while D. melanogaster and D. yakuba have been diverging for about 10 million years (see Fig. 2).
In addition, the high frequency of synonymous substitutions indicates that these inteins have been diverging for a considerable period of time.
For chromosome 3 genes, the average per site silent site divergence (with Jukes Cantor correction) between D. americana and D. virilis is 0.08705 (data not shown; the two species have been diverging for 4.1 Myr [ Morales-Hojas et al. 2011]).
