Journal ArticleDOI

TL;DR: A timescale for early land plant evolution that integrates over topological uncertainty by exploring the impact of competing hypotheses on bryophyte−tracheophyte relationships, among other variables, on divergence time estimation is established.
Journal ArticleDOI
Seed plant phylogeny and the origin of angiosperms: An experimental cladistic approach
TL;DR: The results raise the possibility that many features considered key adaptations in the origin and rise of angiosperms were actually inherited from their gymnospermous precursors, and the morphological diversity of Mesozoic anthophytes could provide critical tests of relationships.
Journal ArticleDOI
Early cretaceous fossil evidence for angiosperm evolution
Leo J. Hickey,James A. Doyle +1 more
TL;DR: Comparisons of dated pollen floras of other regions indicate that one major subgroup of angiosperms, tricolpate-producing dicots (i.e., excluding Magnoliidae of Takhtajan) originated in the Aptian of Africa-South America at a time of increasing aridity and migrated poleward into Laurasia and Australasia.

Sesqui-, di-, and triterpenoids as chemosystematic markers in extant conifers—A review
Angelika Otto,Volker Wilde +1 more
TL;DR: With the exception of diterpenoid alkaloids (taxanes), Taxaceae contain terpenoids common in the other conifer families, and this supports their inclusion as a separate family in the major conifer clade.
Journal ArticleDOI
Establishing a time-scale for plant evolution
TL;DR: A post-Jurassic origin of angiosperms and a post-Cambrian origin of land plants are rejected, and it is suggested that the establishment of the major embryophyte lineages occurred at a much slower tempo than suggested in most previous studies.
