To conclude, clear phylogenetic structure with four well-characterized phyla, a long evolutionary history bordering to the origin of life in the prebiotic world, and a diversity of colonized environments made Archaea an attractive subject for the studies of the evolution of protein function.
The main difference between Ohta's nearly neutral theory and Kimura's neutral theory is while Kimura put his focus on so-called "strictly neutral mutations" (this phrase is specified by Ohta), Ohta was more interested in the evolutionary mechanisms of the "border line mutations" or the "nearly neutral mutations," (i.e. mutations which are not strictly neutral nor are strongly selected).
Insertions and translocations in multiple genomes define the borders of evolutionary conserved gene clusters that can be rapidly extracted from our graphs by filtering the edges on the basis of the degree of conservation.
The community context of species' borders: ecological and evolutionary perspectives.
It is an "evolutionary quandary," Kaplan wrote, that "borders on being a story flaw … It makes no sense for the aliens to be such capable human-killing machines.
We explored the evolutionary history of genes encoding brush-border proteins involved in carbohydrate digestion and absorption.
In addition, we report that in Xenopus laevis Smad8 morpholinos prevent somite border formation, which may have evolutionary implications.
The sequence is in contrast to the bordering regions of ribosomal subunits evolutionary not conserved, thus genetic differentiation is detectable even in closely related groups of organisms.
We investigated the evolutionary history of nine genes encoding brush-border proteins involved in carbohydrate digestion/absorption. Results indicated widespread adaptive evolution in mammals, with several branches experiencing episodic selection, particularly strong in bats.
Thus, here we considered partially distinct sub-populations, those that are distinct in a subset of the data, still exchange genes, and intergrade at their borders, to be subspecies or evolutionary significant units of more inclusive species units.
