...The new TimeTree resource now adds data from asteroid impacts (Earth Impact Database), solar luminosity (Gough 1981), and atmosphere composition, including oxygen (Holland 2006) and carbon dioxide (Berner 1990; Petit et al. 1999; Hessler et al. 2004; Beerling and Royer 2011)....

...Thus, the TimeTree project has been advancing the process of knowledge discovery by enabling data-driven retrieval of peer-reviewed publications and estimates of time of divergence between species that are relevant to the user’s query (Hedges et al. 2006; Kumar and Hedges 2011)....

...To make these results easily accessible to evolutionary and non-evolutionary biologists, we are collecting and synthesizing divergence time estimates from all published studies in the TimeTree resource (Hedges et al. 2006; Kumar and Hedges 2011)....

...This new approach is very quick for mining all relevant studies, because the previous method to scan each study individually (Hedges et al. 2006) becomes time consuming due to a large number of taxa in timetrees of each study and the number of studies in the database....

...Solid circles mark nodes that map directly to the NCBI Taxonomy and the open circles indicate nodes that were created during the polytomy resolution process described in Hedges et al. (2015). A geologic timescale (showing eons, eras, periods, epochs, and ages) is rendered directly below the timetree (fig....

...…acquisition of timetree data, their standardization, and the assembly of a global timetree (Timetree of Life, TTOL) based on individual timetrees are available in Hedges et al. (2015), where evolutionary and biodiversity analyses of these data were presented for 50,632 species from 2,274 studies....
