Show Summary Details


The idea of an evolutionary clock can be rejected, along with its derivative, the molecular clock. The time course of a phylogeny can be calibrated using fossils, age of islands or strata that include endemic taxa, and spatial correlations between clades and tectonic events. The first two methods have serious limitations, while the third suggests possible lines of research. Problems with tectonic calibrations are discussed. The case studies discussed here include Madagascar and the Philippines.

Keywords: evolutionary clock; molecular clock; fossil age; island age; tectonic calibration
