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.
Our work is the first experimental demonstration of the general tendency of evolution to favor mutational robustness and protein stability in highly polymorphic populations.
The tendency of soil and paleoenvironmental evolution recorded in the Darai Kalon section can be associated with subtropical semi-humid forest and forest-steppe landscapes.
The notable exception to the tendency of gene loss in TLR evolution is found in chicken TLRs 1 and 2, each of which underwent gene duplication about 147 and 65 Mya, respectively.
This is consistent with the recent observation that several proteins common to Archaea and Eukaryotes are missing in either Crenarchaeota, Euryarchaeota or Thaumarchaeota [ 27] and may indicate a possible tendency of evolution by streamlining of some central molecular processes in the archaeal domain.
But he added, "I think the tendency of American intellectuals to learn their evolution from him is unfortunate, and that's putting it mildly".
Thus, the nature of science presented to school teachers emphasizes methodological naturalism, the essential role of empirical evidence, science as social construction, and the tendency of science to change over time (Evolution and the Nature of Science Institutes, 2012).
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].
In addition to estimating the age of each human gene as described above, we also estimated the tendency of a gene to be lost in evolution.
The different paralogs are thought to undergo strong concerted evolution which is the tendency of a family of repeated genes to jointly evolve.
