New evidence from rocks, molecules and machine learning is forcing scientists to redraw the opening chapters of Earth’s story, pushing the first stirrings of biology far closer to the planet’s violent ...

A missing piece of Earth's evolutionary timeline may have been found. Using computational modeling, a team of scientists explored how working backwards from modern biochemistry could help map out how ...

To better understand the circadian clock in modern-day cyanobacteria, a research team has studied ancient timekeeping systems. They examined the oscillation of the clock proteins KaiA, KaiB, and KaiC ...

Bacteria are the most diverse organisms on Earth, with a number of species that’s difficult to quantify. They’re also incredibly old. Bacteria consist of a single cell. They do not have bones and are ...
