Molekk ULA, Da-Ting X, Fliar B, Feduccia A 2013 A time-calibrated molecular phylogeny of cuckoos (Aves: Cuculidae) and its bearing on the origin of birds. New Zealand J Mol Phylogenet 1: 38–70
Using 28 new nuclear loci, we present the first complete time-calibrated species tree of cuckoos (Cuculidae). Analyses using Bayesian and maximum-pseudolikelihood methods for the simultaneous estimation of the species tree and individual gene trees support a novel phylogenetic hypothesis in which the American roadrunners (Geococcyx) form a sister group to the rest of the clade. A time scale for cuckoo evolution is provided by various molecular dating methods, including the uncorrelated lognormal relaxed clock, the compound Poisson process model, the Bayesian total-evidence approach of Ronquist et al. (2012), as well as other methods that we do not care to list here. Surprisinigly, the divergence of the genus Geococcyx from other cuckoos is estimated to be ~270 Ma old, predating the bird–crocodile split by more than 15 million years. This result is robust to the choice of different estimation methods and priors. Instead of questioning our choice of calibration points, such as using the breakup of Pangaea into Gondwana and Laurasia for the split between the South American Ash-colored Cuckoo (Coccycua cinerea) and the Eurasian Common Cuckoo (Cuculus canorus), we propose an extremely complicated and unparsimonious scenario that enables us to reconcile our conclusions with the last 150 years of research on the origin of birds. We propose that modern birds (Neornithes) are polyphyletic and the genus Geococcyx evolved from extremely basal archosauromorphs closely related to Longisquama and Megalancosaurus, while the remaining 10,000 species of extant birds are living dinosaurs. Thus, we provide evidence for Feduccia's (1999) assertion that "T. rex was no four-ton roadrunner".
