Fruit fly abdominal pigmentation may represent an optimal setting to study network evolution, as this trait diversified over short evolutionary time spans.
Diversifying root morphological traits associated with resource acquisition could also have a positive impact.
Given the great diversity among calls of closely related species of frogs and insects, the processes by which such traits diversify remain a compelling problem [5], [6].
Beak size and shape, as well as body size, are the principal phenotypic traits that have diversified in Darwin's finches [ 5].
Tunicates, or Urochordates, are marine deuterostomes characterized by markedly diversified developmental and life history traits, and traditionally encompass three major classes: Ascidiacea (sea squirts), Thaliacea (salps) and Appendicularia (larvaceans).
For example, are entire pathways recruited as a whole or are individual genes co-opted and re-wired de novo [ 12]? How do recruited or rebuilt pathways diversify along with trait diversification?
Numerous lines of evidence point to diversified pathways contributing to the control of both traits, and this control may involve some overlap of several pathways.
The traits that diversify with greatest frequency between different breeds of the same species (Table 11.1) are traits that diversify under sexual selection in nature.
What we found is that unlike your average bro, Alt Bros encompass a wider set of traits that diversify them they're brown, black, white, straight, gay, and fluid.
Conventional hypotheses posit 'reciprocal' or 'sequential' bitrophic interactions between traits of diversifying clades that drive insect and plant radiations [ 10- 12].
