In 1990 Charles Sibley and Jon Ahlquist included auks and skuas in a broader family Laridae.
[4] A molecular phylogenetic study by Baker and colleagues published in 2007 found that the noddies in the genus Anous formed a sister group to a clade containing the gulls, skimmers, and the other terns.
[5] To create a monophyletic family group, Laridae was expanded to include the genera that had previously been in Sternidae and Rynchopidae.
[5] The German palaeontologist Gerald Mayr has questioned the validity of these early dates and suggested that inappropriate fossils were used in calibrating the molecular data.
