The endosymbiotic origin of mitochondria during eukaryogenesis has long been viewed as
an adaptive response to the oxygenation of Earth's surface environment, presuming a …

Abstract The Ediacaran-Cambrian transition, which incorporates the radiation of animals,
lacks a robust global temporal and spatial framework, resulting in major uncertainty in the …

Plant (archaeplastid) evolution has transformed the biosphere, but we are only now
beginning to learn how this took place through comparative genomics, phylogenetics, and …

Brown algae are the only group of heterokont protists exhibiting complex multicellularity.
Since their origin, brown algae have adapted to various marine habitats, evolving diverse …

Although Ce anomalies are commonly used to reconstruct past seawater redox conditions,
published interpretations are based on various proxy materials and analytical approaches …

The Ulvophyceae, a major group of green algae, is of particular evolutionary interest
because of its remarkable morphological and ecological diversity. Its phylogenetic …

Colonization of land from marine environments was a major transition for biological life on
Earth, and intertidal adaptation was a key evolutionary event in the transition from marine-to …

Accumulated records of organic microfossils span billions of years of Earth history. The
majority of this record consists of prokaryotes plus eukaryotes of a protistan grade, yet this …

While there is significant data on eukaryogenesis and the early development of the
eukaryotic lineage, major uncertainties regarding their origins and evolution remain …

The animal phyla and their associated body plans originate from a singular burst of
evolution occurring during the Cambrian period, over 500 million years ago. The phylum …
