Molecular clock ages of component groups in individual distribution patterns form surprisingly smooth curves: does vicariance never occur, or are the clock ages wrong?
Abstract. Molecular studies have dated many component clades in particular biogeographical patterns. Here we review age curves for clades in different patt
