That group points to regions like California, which leads the nation in diversity, but is also a state that struggles with a crumbling infrastructure and the perceived societal stresses of a dramatically diversifying population.
Two major groups of early birds diversified dramatically in the Cretaceous Period: the Enantiornithines, an extinct subclass of birds; and Odontornithes, a primitive offshoot of the subclass Ornithurae that gave rise to modern birds at the end of the Cretaceous.
The creature lived on the ancient supercontinent called Gondwana during the Cambrian Explosion, a period when all creatures inhabited the seas and life on the planet diversified dramatically.
Extant mammals diversified dramatically, featuring more than 100-fold difference in species maximum lifespan, 100-million-fold difference in body mass and adaptations to both terrestrial and aquatic life as well as to powered flight and subterranean life.
He gives to wheat the title "world conqueror," saying, "It has diversified more dramatically, invaded more new habitats, multiplied faster and evolved more rapidly without extinction than any other known organism".
We can formulate several hypotheses as to why white-eyes have diversified so dramatically compared with other bird clades.
Here, we present a high-quality reference genome of the silvereye and use it as a model to address hypotheses as to why white-eyes have diversified so dramatically.
Late in the past decade, the frequency of itraconazole resistance dramatically increased, and CYP51 mutations notably diversified under selective pressure of long-term azole treatment of patients with chronic and allergic aspergillosis.
In comparison to their more recently diversified sister taxa, the flowering plants, gymnosperms possess dramatically larger genomes (Bowe et al. 2000; Peterson et al. 2002; Morse et al. 2009; Zonneveld 2012).
