For example, in Dalechampia over half (15) of 29 reconstructed speciation events associated with increased quantitative phenotypic disparity (morphological divergence) involved no change in pollinators (reanalysed from data in Armbruster 1993).
Then when you factor in the 'great income disparity' or Great Divergence that we've seen since 1980, diligently expressed by Tim Noah on CBS Sunday Morning, this is the other talking point that needs to get out there... the 1% have done enormously well.
Adaptive radiations commonly generate a distinctive pattern of temporal change in disparity, where morphological divergence increases quickly in the first phase, and slows down towards present time, as the niches are filled [ 22].
Whether these apparent disparities reflect biological divergence sufficient to translate into distinct ecological regimes (or animal reservoirs) bears investigation.
For protein-coding genes, previous studies have shown large disparities in sequence divergence between brain- and testis-expressed genes, both in the CDS and UTR, owing to the stronger functional constraint on the brain-expressed genes [ 20, 21].
Disparity measures the morphological divergence among taxa and is a measure of the variety of organisms, rather than simply their numbers [50].
The disparity between X/A diversity versus divergence thus implies that positive natural selection acts more frequently on the X chromosome than the autosomes.
Furthermore, corrected pairwise divergences (K) and estimated branch lengths indicate substantial disparities in the level of divergence of atp1 compared to coxI and matR in these parasites relative to non-parasites (Fig. 3A F).
Moving up from the root of the phylogeny, a mean disparity is calculated at each node (divergence event) as the average of the relative disparities of all lineages whose ancestral lineages were present at that point [ 91].
The evolution of locomotor phenotypes was characterized by selection towards at least two distinct adaptive peaks and the early divergence of modern morphological disparity.
