The age of the angiosperms: a molecular timescale without a clock
The age of the angiosperms has long been of interest to botanists and evolutionary
biologists. Many early efforts to date the age of the angiosperms and evolutionary …

Evaluating the impact of genomic data and priors on Bayesian estimates of the angiosperm evolutionary timescale
The evolutionary timescale of angiosperms has long been a key question in biology.
Molecular estimates of this timescale have shown considerable variation, being influenced …

An uncorrelated relaxed-clock analysis suggests an earlier origin for flowering plants
SA Smith, JM Beaulieu… - Proceedings of the …, 2010 - National Acad Sciences
We present molecular dating analyses for land plants that incorporate 33 fossil calibrations,
permit rates of molecular evolution to be uncorrelated across the tree, and take into account …

The age and diversification of the angiosperms re‐revisited
• Premise of the study: It has been 8 years since the last comprehensive analysis of
divergence times across the angiosperms. Given recent methodological improvements in …

Fossil data support a pre-Cretaceous origin of flowering plants
Flowering plants (angiosperms) are the most diverse of all land plants, becoming abundant
in the Cretaceous and achieving dominance in the Cenozoic. However, the exact timing of …

Heterogeneous rates of molecular evolution and diversification could explain the Triassic age estimate for angiosperms
Dating analyses based on molecular data imply that crown angiosperms existed in the
Triassic, long before their undisputed appearance in the fossil record in the Early …

Using fossils to break long branches in molecular dating: a comparison of relaxed clocks applied to the origin of angiosperms
S Magallón - Systematic Biology, 2010 - academic.oup.com
Long branches are potentially problematic in molecular dating because they can
encompass a vast number of combinations of substitution rate and time. A long branch is …
