A remarkable result was the observation that orthologs with low nonsynonymous substitution rate (dN) were associated with specific amino acid characters, such as higher polarity and electrostatic charge, and large molecular volume (Additional file 6), possibly reflecting physico-chemical tendencies of the evolution of genes.
Another observable tendency in the evolution of the structures is the formation of faceted structures with a distinct angle towards the global surface normal.
Its monophyly and prolonged existence since the late Miocene also suggest the strong tendency in the evolution of this clade to retain the ancestral ecological niche, presenting an apparent case of strong 'phylogenetic niche conservatism' (Kozak et al.2006 Wiens20044).2006 Wiens2004
Taken together, these results suggest a similar tendency in the evolution of major TF families in plants.
Its anatomy typifies the tendency of bird evolution on oceanic islands, with few predators and abundant food: a generally robust physique, with accretion of thermodynamic efficiency at the expense of flight abilities, reduced wing muscles, and a diminished keel on the sternum.
Consequently it is worth analysing the conservation of the local structural tendency in relation to the evolution of the rest of the protein modules.
Our work is the first experimental demonstration of the general tendency of evolution to favor mutational robustness and protein stability in highly polymorphic populations.
Combined feeding on rotten material and the acquired hindgut community permitted the loss of the amino acid-biosynthetic pathways in the BCpu genome, following the general tendency of reductive genome evolution found in obligatory insect endosymbionts (Moran et al. 2008; Moya et al. 2008).
Concerted evolution is the tendency of the different genes in a gene family or cluster to evolve in concert, resulting in sequence homogenization among the members of the family [ 1].
Third, many authors have recognized that whatever trends or tendencies there are in the evolution of individuals, there have also been changes over evolutionary time in the social relations between individuals (e.g., Frank 1998).
The same tendencies were observed for the evolution of hatchability according to the egg set rates.
