Scientists discovered complex life may have started 1.5 billion years earlier than previously thought thanks to phosphorus.

When we imagine the search for life on Mars, we often picture high-tech rovers scanning dusty landscapes or orbiters ...

To best utilize the fossil record, they leveraged fossils of eukaryotes, whose mitochondria evolved from Alphaproteobacteria, and chloroplasts evolved from cyanobacteria to better estimate how and ...

It may be that oxygen in the atmosphere, thanks to emissions from photosynthesizing cyanobacteria and algae ... which left a huge number of fossils. Trilobites had flattened, segmented, plated ...

To best utilise fossil records, the researchers included genes from mitochondria (related to alphaproteobacteria) and chloroplasts (related to cyanobacteria), which allowed them to use data from ...

The abundance of cyanobacteria and other bacteria that use light energy—primarily anaerobic oxygenic phototrophs (AAPs)—was on average 32 times higher under lit conditions than under dark ...

To best utilize fossil records, the researchers included genes from mitochondria (related to alphaproteobacteria) and chloroplasts (related to cyanobacteria), which allowed them to use data from early ...
