Because evolutionary distances should not be changed by merely adding species to a tree, node counting is not an accurate way to measure evolutionary distance.
"If government is changed not by evolutionary methods, but revolutionary methods, this is a catastrophe," he said, adding that Mr. Putin "is the only choice.
Is our culture already being changed in ways that we don't realize by evolutionary thinking?
While numerical changes in population size may seem like a purely ecological issue, in fact these ecological changes will likely be followed by evolutionary changes, because the selective pressures on many traits will change with changing community contexts.
Although glycosylation of HA can modify antibody based immunity, CD8+ T-cell epitopes have been highly conserved since the 1930s [ 28, 29], and therefore, T-cell based immunity should be unaffected by evolutionary changes in HA.
Thus, during the 2009 2010 outbreak, the occurrence of isolates from a second complex in the highland region (clonal complex 3) and the arid and semi-arid region (clonal complex 2) cannot be explained by evolutionary changes.
Lankau et al. (2009) suggested that what appears as decreasing ability to compete with native species during their expansion at a given location can be explained by evolutionary changes within A. petiolata populations; hence, old populations produced less glucosinolates, which are toxic to other plant species than populations who had recently invaded a new area.
Those cultural changes happened far too quickly to be accompanied by evolutionary (genetic) changes leading to increased rates of overweight and obesity (Power 2012).
We argue that the persistence or extinction of a focal species can be determined solely by evolutionary change in an interacting species.
In such an unequal system, at least the cooler star has certainly been affected by evolutionary changes, and probably so has the brighter one.
