Eukaryogenesis and oxygen in Earth history
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 …

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

1.63-billion-year-old multicellular eukaryotes from the Chuanlinggou Formation in North China
Multicellularity is key to the functional and ecological success of the Eukarya, underpinning
much of their modern diversity in both terrestrial and marine ecosystems. Despite the …

Is there such a thing as a biosignature?
The concept of a biosignature is widely used in astrobiology to suggest a link between some
observation and a biological cause, given some context. The term itself has been defined …

Frameworks for interpreting the early fossil record of eukaryotes
SM Porter, LA Riedman - Annual Review of Microbiology, 2023 - annualreviews.org
The origin of modern eukaryotes is one of the key transitions in life's history, and also one of
the least understood. Although the fossil record provides the most direct view of this process …

New record of the green algal fossil Proterocladus and coexisting microfossils from the Meso-Neoproterozoic Diaoyutai Formation in southern Liaoning, North China
Abstract The Mesoproterozoic-Neoproterozoic transition represents a crucial interval of
evolutionary innovation and phylogenetic diversification. A spotty fossil record indicates that …

Systematic paleontology of macroalgal fossils from the Tonian Mackenzie Mountains Supergroup
Proterozoic eukaryotic macroalgae are difficult to interpret because morphological details
required for proper phylogenetic studies are rarely preserved. This is especially true of …
