The molecular clock presents a means of estimating evolutionary rates and timescales using
genetic data. These estimates can lead to important insights into evolutionary processes and …

Molecular dating analyses allow evolutionary timescales to be estimated from genetic data,
offering an unprecedented capacity for investigating the evolutionary past of all species …

Beetles constitute the most biodiverse animal order with over 380 000 described species
and possibly several million more yet unnamed. Recent phylogenomic studies have arrived …

Species are fundamental units in biological research and can be defined on the basis of
various operational criteria. There has been growing use of molecular approaches for …

Cyanobacteria are among the most ancient of evolutionary lineages, oxygenic
photosynthesizers that may have originated before 3.0 Ga, as evidenced by free oxygen …

Primates have long been a test case for the development of phylogenetic methods for
divergence time estimation. Despite a large number of studies, however, the timing of …

The systematics of the genera and subgenera within the soft tick family Argasidae is not
adequately resolved. Different classification schemes, reflecting diverse schools of scientific …

Understanding the history and philosophy of biological systematics (phylogenetics,
taxonomy and classification of living things) is key to successful practice of the discipline. In …

Studies in evolutionary biology and biogeography increasingly rely on the estimation of
dated phylogenetic trees using molecular clocks. In turn, the calibration of such clocks is …

The need for robust estimates of times of divergence is essential for downstream analyses,
yet assessing this robustness is still rare. We generated a time-calibrated genus-level …
