The most serious test for any theory is always new data, and in the second section I review the Athenian burials which have been published since 1985.
These, I suggest, have done little to change the patterns which were apparent a decade ago.
accounting for 'ghost' lineages in the fossil record and developing more realistic models of rate evolution for molecular genetic sequences), the consistent and conspicuous disagreement between these two sources of data more likely reflects a genuine difference between estimated ages of (i) stem-group origins and (ii) crown-group morphological diversifications, respectively.
Based on a strict interpretation of the fossil record (i.e. The conflicting age estimates thus have different implications regarding the influence of the K-Pg mass extinctions on the evolutionary radiation of modern birds.
