First, two species or higher taxa are queried (e.g., cat and dog). Next, TimeTree looks for these species in the TTOL to find their most recent common ancestor (MRCA). When one or both of the species are not present in TTOL, the NCBI taxonomy is scanned to find the closest relatives of the species or higher taxa requested by the user. Then, those taxa are used as proxies to find the MRCA for the given query. Finally, the divergence time for the MRCA is retrieved from the TimeTree database.
