The photosynthetic organelle of algae and plants (the plastid) traces its origin to a primary
endosymbiotic event in which a previously non‐photosynthetic protist engulfed and …

▪ Abstract Over the past several decades, our knowledge of the origin and evolution of
mitochondria has been greatly advanced by determination of complete mitochondrial …

The appearance of photosynthetic eukaryotes (algae and plants) dramatically altered the
Earth's ecosystem, making possible all vertebrate life on land, including humans. Dating …

The red algal order Bangiales has been revised as a result of detailed regional studies and
the development of expert local knowledge of Bangiales floras, followed by collaborative …

By synthesizing data from individual gene phylogenies, large concatenated gene trees, and
other kinds of molecular, morphological, and biochemical markers, we begin to see the …

Previous phylogenetic studies of the Rhodophyta have provided a framework for
understanding red algal phylogeny, but there still exists the need for a comprehensive …

Steroids, a class of triterpenoid lipids with high preservation potential, are widely distributed
in sedimentary rocks. All eukaryotes have a physiological requirement for these molecules …

Secondary endosymbiosis is the process that drives the spread of plastids (chloroplasts)
from one eukaryote to another. The number of times that this has occurred and the kinds of …

The wondrously diverse eukaryotes that constitute the red algae have been the focus of
numerous recent molecular surveys and remain a rich source of undescribed and little …

I discuss the evidence for a single origin of primary plastids in the context of a paper in this
issue challenging this view, and I review recent evidence concerning the number of …
