If the ancestor Y. pestis strain was DFR12 positive, genomovar14 and strain Angola must abandon DFR12 from their genomes again, which can not be well explained by maximum parsimony principle in the evolution.
The basic principle in the evolution of life was "to live long enough to reproduce".
Progenesis is discussed as a principle in the evolution of meiofaunal taxa [ 67], and acochlidian morphology might have evolved by retention of the juvenile characters of an aberrant developmental form of an early pulmonate.
This perspective reveals two common principles in the structural evolution of mitochondrial ribosomes and OXPHOS complexes, which we argue resulted from two common evolutionary mechanisms acting exclusively on mitochondrially encoded components.
But research with pathogenic fungi suggests general principles at work in the evolution of pathogen genomes, and to enable a more holistic understanding of the forces shaping genomes of mutualists, we focus on the genus Amanita and the role of ecology in genome evolution.
Nonsurgical treatment strategies for breast cancer are at present reserved for the treatment of established malignancy, but from first principles any stage in the evolution of malignancy can be targeted.
In principle, the evolution of soil resources can be constrained by comparing the rates of soil erosion and production.
In principle, the evolution of the surface is determined by the rate of the surface reaction which dissolves the solid surface.
Genetic correlations between components of such combinatorial traits, in the form of pleiotropic or tightly linked genes, can in principle promote the evolution and maintenance of these traits.
Of the early attempts, the most influential was that of a French psychologist, Théodule-Armand Ribot, who, in his Diseases of Memory (1881, English translation 1882), endeavoured to account for memory loss as a symptom of progressive brain disease by embracing principles describing the evolution of memory function in the individual, as offered by an English neurologist, John Hughlings Jackson.
