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 evolutionary diversification. We examine the evolutionary diversification of angiosperms and the observed differential distribution of species in angiosperm clades by estimating the rate of diversification for angiosperms as a whole and for a large set of angiosperm clades. We also identify… 
Angiosperm diversification through time.
TLDR
Angiosperm diversity is found to have mixed origins: slightly less than half of the living species belong to lineages with low to moderate diversification rates, which appeared between 130 and 102 Mya (Barremian-uppermost Albian; Lower Cretaceous).
Understanding angiosperm diversification using small and large phylogenetic trees.
TLDR
It is found that diversification rate shifts are not directly associated with the major named clades examined here, with the sole exception of Fabaceae in the GenBank mega-phylogeny.
Thirty clues to the exceptional diversification of flowering plants
TLDR
The identified deep time diversification shifts are clues to the identification of ultimate drivers of angiosperm megadiversity, which probably involve multivariate interactions among intrinsic traits and extrinsic forces.
Thirty clues to the exceptional diversification of flowering plants
TLDR
This work investigates how angiosperms became megadiverse by identifying the phylogenetic and temporal placement of exceptional radiations, by combining the most densely fossil-calibrated molecular clock phylogeny with a Bayesian model that identifies diversification shifts among evolutionary lineages and through time.
MORPHOLOGICAL RATES OF ANGIOSPERM SEED SIZE EVOLUTION
  • H. Sims
  • Biology
    Evolution; international journal of organic evolution
  • 2013
TLDR
Results suggest that evolutionary rates (morphological and taxonomic) are elevated in densely occupied regions of the seed morphospace relative to lineages whose ecophenotypic innovations have moved them toward the edges.
Slowly but surely: gradual diversification and phenotypic evolution in the hyper-diverse tree fern family Cyatheaceae
TLDR
This study indicates that Cyatheaceae is a diverse clade which slowly accumulated morphological, ecological and taxonomic diversity over a long evolutionary period and provides a compelling example of the tropics as a museum of biodiversity.
Seed size and its rate of evolution correlate with species diversification across angiosperms
TLDR
It is shown that absolute seed size and the rate of change in seed size are both associated with variation in diversification rates, and that smaller-seeded plants had higher rates of diversification, possibly due to improved colonisation potential.

Evolutionary diversification of clades of squamate reptiles
TLDR
Diversification in squamate lineages was independent of their stem age, but strongly related to the area of the region within which they occur, suggesting negative feedback of species richness on the rate of diversification.

Phylogenies and angiosperm diversification
TLDR
Cladistic evidence that Pentoxylon, Bennettitales, and Gnetales are the sister group of angiosperms implies that the angiosperm line (angiophytes) existed by the Late Triassic, and "Tree-thinking" clarifies discussions of the age of groups, by distinguishing between splitting of the stem-lineage from its sister group and splits of the crown-group into extant clades.
Lower Species Richness in Dioecious Clades
  • J. C. Heilbuth
  • Biology, Environmental Science
    The American Naturalist
  • 2000
TLDR
It is suggested that Baker’s law is not the reason for the poor representation of dioecy among angiosperm species, and self‐compatible lineages may have higher rates of allopatric speciation than hermaphroditic self‐incompatible angiosperms.
PHYLOGENETIC ANALYSIS OF TRAIT EVOLUTION AND SPECIES DIVERSITY VARIATION AMONG ANGIOSPERM FAMILIES
TLDR
A molecular phylogeny of the angiosperm families is used to reanalyse correlations between S and family‐level traits and use reconstructions of trait evolution to interpret the results and confirm that pollination mode and growth form are correlated with S.
POLLINATION SYSTEMS, DISPERSAL MODES, LIFE FORMS, AND DIVERSIFICATION RATES IN ANGIOSPERM FAMILIES
  • O. Eriksson, B. Bremer
  • Environmental Science
    Evolution; international journal of organic evolution
  • 1992
TLDR
An important aspect of evolution in higher order taxa, such as mammals, molluscs, and plants, is the rate of diversification (R), and several authors have suggested reproductive and life form features associated with high diversification rates among angiosperms.
Angiosperm phylogeny inferred from multiple genes as a tool for comparative biology
TLDR
The results of parsimony analyses of DNA sequences of the plastid genes rbcL and atpB and the nuclear 18S rDNA for 560 species of angiosperms and seven non-flowering seed plants are reported and show a well-resolved and well-supported phylogenetic tree for the angios perms for use in comparative biology.
MORPHOLOGICAL DIVERSIFICATION AND ADAPTIVE RADIATION: A COMPARISON OF TWO DIVERSE LIZARD CLADES
TLDR
Examination of the position of species in multidimensional space indicates that the morphological diversity of Anolis, which the authors refer to as disparity, is significantly greater than that of Sceloporus, and one potential explanation for this pattern is that morphological diversification in Anolis was facilitated by the evolution of subdigital toe‐pads, which allow anoles to use the environment in ways not available to S celoporus.
Comparing palynological abundance and diversity; implications for biotic replacement during the Cretaceous angiosperm radiation
TLDR
Analysis of an updated and expanded database of North American palynological samples from Cretaceous sediments document a rapid increase in angiosperm diversity and abundance within individual fossil palynofloras (represent- ing local/subregional vegetation).
Age and rate of diversification of the Hawaiian silversword alliance (Compositae).

  • Environmental Science

  • 1998
TLDR
This work took advantage of rate-constant rDNA sequence evolution and an "external" calibration using paleoclimatic and fossil data to determine the maximum age and minimum diversification rate of the Hawaiian silversword alliance (Compositae), a textbook example of insular adaptive radiation in plants.
The earliest angiosperms: evidence from mitochondrial, plastid and nuclear genomes
TLDR
This study demonstrates that Amboreella, Nymphaeales and Illiciales-Trimeniaceae-Austrobaileya represent the first stage of angiosperm evolution, with Amborella being sister to all other angiosperms, and shows that Gnetales are related to the conifers and are not sister to the angios perms, thus refuting the Anthophyte Hypothesis.
Shifts in Diversification Rate with the Origin of Angiosperms
TLDR
Four hypotheses for the basal relationships of angiosperms were examined by methods that are robust to uncertainty about the timing of internal branch points.
