ABSOLUTE DIVERSIFICATION RATES IN ANGIOSPERM CLADES
Abstract The extraordinary contemporary species richness and ecological predominance of flowering plants (angiosperms) are even more remarkable when considering the relatively recent onset of their… Expand
A metacalibrated time-tree documents the early rise of flowering plant phylogenetic diversity.
The establishment of modern terrestrial life is indissociable from angiosperm evolution. While available molecular clock estimates of angiosperm age range from the Paleozoic to the Late Cretaceous,… Expand
Ferns diversified in the shadow of angiosperms
The rise of angiosperms during the Cretaceous period is often portrayed as coincident with a dramatic drop in the diversity and abundance of many seed-free vascular plant lineages, including ferns.… Expand
Angiosperm diversification through time.
The extraordinary diversity of angiosperms is the ultimate outcome of the interplay of speciation and extinction, which determine the net diversification of different lineages. We document the… Expand
Phylogenetic pattern, diversity, and diversification of Eudicots
Phylogeny of Basal Eudicots Based on Three Molecular Data Sets: atpB, rbcL, and 18s Nuclear Ribosomal DNA Sequences
Land plant evolutionary timeline: gene effects are secondary to fossil constraints in relaxed clock estimation of age and substitution rates.
UNLABELLED PREMISE OF THE STUDY Land plants play an essential role in the evolution of terrestrial life. Their time of origin and diversification is fundamental to understanding the evolution of… Expand
Phylogenetic relationships and evolution of growth form in Cactaceae (Caryophyllales, Eudicotyledoneae).
PREMISE OF THE STUDY Cactaceae is one of the most charismatic plant families because of the extreme succulence and outstanding diversity of growth forms of its members. Although cacti are conspicuous… Expand
Use of Simultaneous Analyses to Guide Fossil‐Based Calibrations of Pinaceae Phylogeny
Uncertainties in the age and phylogenetic position of Pinaceae fossils present significant obstacles to our understanding of the timing of diversification in the family. We demonstrate that… Expand
Using fossils to break long branches in molecular dating: a comparison of relaxed clocks applied to the origin of angiosperms.
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 suspected to have biased… Expand
