There are four genera and 21 species of albatrossses (Gill and Donsker 2012a).
In a second, unbiased analysis, we examined intraspecific genetic information from 437 conventional avian species, finding a median of 2.four evolutionary units per species, which could be considered proxies for phylogenetic species.
