Insects possess a surprisingly extensive fossil record. Compilation of the geochronologic
ranges of insect families demonstrates that their diversity exceeds that of preserved …

Phylogenetic niche conservatism (PNC) is the tendency of lineages to retain their niche‐
related traits through speciation events. A recent surge in the availability of well‐sampled …

Competition among species and entire clades can impact species diversification and
extinction, which can shape macroevolutionary patterns. The fossil record shows successive …

Here we present a phylogeny of beetles (I nsecta: C oleoptera) based on DNA sequence
data from eight nuclear genes, including six single‐copy nuclear protein‐coding genes, for …

Growing evidence of morphological diversity in angiosperm flowers, seeds and pollen from
the mid Cretaceous and the presence of derived lineages from increasingly older geological …

Mid‐Cretaceous (Barremian‐Turonian) plankton preserved in deep‐sea marl, organic‐rich
shale, and pelagic carbonate hold an important record of how the marine biosphere …

The extraordinary contemporary species richness and ecological predominance of flowering
plants (angiosperms) are even more remarkable when considering the relatively recent …

Phytochrome is a plant regulatory photoreceptor that mediates red light effects on a wide
variety of physiological and molecular responses. DNA blot analysis indicates that the …

In today's angiosperm-dominated terrestrial ecosystems, leptosporangiate ferns are truly
exceptional—accounting for 80% of the≈ 11,000 nonflowering vascular plant species …

Oleanane has been reported in Upper Cretaceous and Tertiary source rocks and their
related oils and has been suggested as a marker for flowering plants. Correspondence of …
