But even during the early years the culture of the settlers had begun to diverge from that of the old country because of their very different social, cultural and geographical context, and this divergence would accelerate from generation to generation.
This is even more likely in cases where sequence divergence is accelerated via positive selection driven by the acquisition of novel function(s).
Positive diversifying selection is an evolutionary force that favors new mutations conferring a fitness advantage and thus leads to an increase in gene diversity and accelerates divergence between homologous proteins.
Conversions involving pseudogenes could accelerate gene family evolution, and may accelerate divergence of some gene families relative to their orthologs.
Can such a model explain the unstable timing of Argentina's decline, with periods of accelerated divergence (the 1980s) and some of moderate convergence (the 1960s)?
To investigate whether nGPCR duplicates exhibit an accelerated divergence that could serve new functions, we compared the sequence divergence of the two WGD-derived duplicates.
Again, in the human FKH family, where the DNA binding domain is highly conserved across family members, the rest of the protein domains exhibit an accelerated divergence relative to the DNA binding domain immediately after duplication (data not shown).
Specifically, homologous but rearranged chromosomes may not be able to undergo proper pairing and/or disjunction during meiosis, thus can suppress recombination and accelerate divergence and speciation by reducing hybrid fitness [5].
This method has proven useful to discriminate between different scenarios resulting in accelerated divergence.
Perhaps more likely is the following possible explanation that postulates a basis for accelerated divergence.
