Introduction Paleontological data have been used for decades to address a series of very general and intrinsically interesting questions concerning speciation. Many of them are essentially microevolutionary, morphological or both. What is the relative prevalence of anagenesis and cladogensis (Wagner & Erwin 1995)? Do constraints on morphology cause occupation of morphospace to slow down as diversity increases (Foote 1993)? Ismorphological change gradual or punctuated across speciation events…

We paleontologists have grown accustomed to facing questions regarding the causes of extinction of great groups of organisms now long vanished. As a rule, we perform with aplomb and circumspection:

Pulses of speciation appear sometimes to be associated with climate change, although moderate oscillations of climate do not necessarily promote speciation despite forcing changes in species' geographical ranges.

Global patterns of diversification in the history of modern amphibians

A phylogenetic timetree based on a multigene data set of 3.75 kb for 171 species reveals several episodes of accelerated amphibian diversification, which do not fit models of gradual lineage accumulation.

Macroevolutionary inferences from primate phylogeny

Evidence that the net rate of cladogenesis increased in the lineage leading to the Cercopithecidae (Old World monkeys), and that there have been further increases in some lineages within that family, suggests the occurrence of clade selection, although the selected trait or traits are not identified.

Data are presented showing that even diverse individual fossil collections merely yield a noisy version of the same pattern seen in the overall continental data set, suggesting that environmental perturbations do not have simple effects on the biota.

Calibrating the Ordovician Radiation of marine life: implications for Phanerozoic diversity trends.

A global-scale sample of fossil occurrences is analyzed that allows us to determine directly the effects of sample size on the calibration of what is generally thought to be among the most significant global biodiversity increases in the history of life: the Ordovician Radiation.

A new database of this kind for the Phanerozoic fossil record of marine invertebrates is introduced and four substantially distinct analytical methods that estimate taxonomic diversity by quantifying and correcting for variation through time in the number and nature of inventories are applied.

Mammals as a Key to Evolutionary Theory

Preliminary tests using the late Neogene records of the Americas and Africa suggest that major aspects of the Great American Interchange have parallels in the African record, as predicted by the habitat theory.

Paleofaunal data confirm that there were fewer mammalian species during the latest Cretaceous than during any interval of the Cenozoic, and that a massive diversification took place during the early Paleocene, immediately after a mass extinction.
