Divergence, Big Time [PDF]

open access: yesJournal of Economic Perspectives, 1997
Historical data are unnecessary to demonstrate that perhaps the basic fact of modern economic history is massive absolute divergence in per capita income across countries. A plausible lower bound on per capita income can be combined with estimates of its current level in the poorer countries to place an upper bound on long-run income growth.

TimeTree2: species divergence times on the iPhone [PDF]

open access: yesBioinformatics, 2011
AbstractSummary: Scientists, educators and the general public often need to know times of divergence between species. But they rarely can locate that information because it is buried in the scientific literature, usually in a format that is inaccessible to text search engines.

Dating the time of viral subtype divergence [PDF]

open access: yesBMC Evolutionary Biology, 2008
AbstractPrecise dating of viral subtype divergence enables researchers to correlate divergence with geographic and demographic occurrences. When historical data are absent (that is, the overwhelming majority), viral sequence sampling on a time scale commensurate with the rate of substitution permits the inference of the times of subtype divergence ...

Ancient Mitogenomes Provide New Insights into the Origin and Early Introduction of Chinese Domestic Donkeys

open access: yesFrontiers in Genetics, 2021
Both molecular data and archaeological evidence strongly support an African origin for the domestic donkey. Recent genetic studies further suggest that there were two distinct maternal lineages involved in its initial domestication.

Fossils, Molecules, Divergence Times, and the Origin of Lissamphibians [PDF]

open access: yesSystematic Biology, 2007
A review of the paleontological literature shows that the early dates of appearance of Lissamphibia recently inferred from molecular data do not favor an origin of extant amphibians from temnospondyls, contrary to recent claims. A supertree is assembled using new Mesquite modules that allow extinct taxa to be incorporated into a time-calibrated ...
