Abstract: "Molecular phylogenies are available for more taxa and ecosystems, but it is debated whether they can be used to estimate separately speciation and extinction rates. [Investigators] selected data to address known concerns and used them to determine median extinction estimates from statistical distributions of probable values for terrestrial plants and animals. [They] then created simulations to explore effects of violating model assumptions. Finally, [they] compiled estimates of diversification-the difference between speciation and extinction rates for different taxa." |

P.456 left column bottom paragraph: "Rates of Diversification-Median rates of diversification were approximately 0.1 species per million species years (Table 1). All but one of the intervals that spanned 95% of the estimated diversification rates were below 1 species per million species years (Table 1)." P.459 right column bottom paragraph: "Diversification Rates: Median diversification rates were from ~0.05 to ~0.2 new species per species per million years for a disparate group of animals and plants (Table 1). Diversification rates >1.0 were exceptional." See notes beneath table |
