Polyploidy (or whole-genome doubling) is a key mechanism for plant speciation leading to
new evolutionary lineages. Several lines of evidence show that most species among …

To date, the vast majority of fossils described for the extinct conifer family, the
Cheirolepidiaceae, have been reported from compression/impressions primarily from …

Van de Peer and colleagues (Fawcett et al., 2009; Lohaus and Van de Peer, 2016) have
written thought-provoking reviews and commentaries on the nonrandom accumulation of …

The 'living fossil'Ginkgo biloba L. is the only extant representative of Ginkgophyta, which is
an ancient group of gymnosperms that constituted an important component of the Earth's …

All flowering plants are now recognized as diploidized paleopolyploids (Jiao et al., 2011;
One Thousand Plant Transcriptomes Initiative, 2019), and polyploid species comprise …

Polyploidy is a dominant feature of extant plant diversity. However, major research
questions, including whether polyploidy is important to long‐term evolution or is just …

Cheirolepidiaceae leaves and pollen are recorded from Valanginian–Albian strata of
southeastern Australia that were deposited at high-latitudes under cool, moist climates in …

A broad difference in the frequencies of plant and animal polyploidy (whole-genome
duplication, WGD) has been recognized since the early 20th century (eg Gates, 1924; …

Phylogenetic conflicts limit our understanding of the evolution of terrestrial life under multiple
whole genome duplication events, and the phylogeny of early terrestrial plants remains full …

Studies of the macroevolutionary legacy of polyploidy are limited by an incomplete sampling
of these events across the tree of life. To better locate and understand these events, we …
