Woese and Fox's 1977 paper on the discovery of the Archaea triggered a revolution in the
field of evolutionary biology by showing that life was divided into not only prokaryotes and …

Protists are the dominant eukaryotes in the biosphere where they play key functional roles.
While protists have been studied for over a century, it is the high-throughput sequencing of …

Eukaryotic life appears to have flourished surprisingly late in the history of our planet. This
view is based on the low diversity of diagnostic eukaryotic fossils in marine sediments of mid …

In modern oceans, eukaryotic phytoplankton is dominated by lineages with red algal-derived
plastids such as diatoms, dinoflagellates, and coccolithophores. Despite the ecological …

Establishing a unified timescale for the early evolution of Earth and life is challenging and
mired in controversy because of the paucity of fossil evidence, the difficulty of interpreting it …

INTRODUCTION Bacteria are the most diverse and abundant cellular organisms on Earth,
and in recent years environmental genomics has revealed the existence of an enormous …

Detailed structural, biochemical, cell biological, and genetic studies of any gene/protein are
required to develop models of its actions in cells. Studying a protein family in the aggregate …

Fungi are crucial components of modern ecosystems. They may have had an important role
in the colonization of land by eukaryotes, and in the appearance and success of land plants …

Photosynthesis evolved in eukaryotes by the endosymbiosis of a cyanobacterium, the future
plastid, within a heterotrophic host. This primary endosymbiosis occurred in the ancestor of …

The~ 1.6 Ga Tirohan Dolomite of the Lower Vindhyan in central India contains phosphatized
stromatolitic microbialites. We report from there uniquely well-preserved fossils interpreted …
