However, the hypothesis is not meant to explain the evolutionary fate of the underlying mechanisms and/or the evolution of cooperation (an excellent overview is in [ 29]).
The good news is that, in our re-evaluation, nine states and the District of Columbia receive a grade of A, indicating that the treatment of evolution is excellent or very good.
Case studies offer creators of works of evolution by example a range of excellent opportunities not afforded to creators of general works.
The phylogenetic context of gene duplication is of great importance in understanding which gene copies are truly comparable, and how gene copies may have diversified and taken on novel functions during grass evolution (for an excellent review of the complex patterns of gene duplication in a number of key developmental genes across grasses, see Malcomber et al., 2006).
The evolution of pregnancy is an excellent system in which to study the origin of novelties because mammals preserve stages in the transition from egg laying to live birth.
Certainly, the biphasic model of evolution depicted in Fig. 2 is not all-encompassing as continuous, long-term increase in genome complexity (but not necessarily biological information density) is observed in various lineages, our own history (that is, evolution of vertebrates) being an excellent case in point.
Nevertheless, the currently available evolutionary models of reductive plastome evolution provide excellent starting points for leaving the paths of descriptive science towards hypothesis-driven research.
The evolution of pheromone diversity is an excellent resource to evaluate the role of sensory systems in speciation, both for its prevalence among several taxa and its definitive signal [ 4].
The success of invertebrates throughout evolution is an excellent illustration of the efficiency of their defence strategies.
How economic level influences acceptance of evolution is an excellent direction for future research.
However, evolution has led to there being many real animals capable of excellent locomotion.
