What is the molecular clock? Levels of molecular variation could be used, in principle, to estimate divergence times, serving as evolutionary "clocks" that "tick" at different rates. Subsequent ...

The term 'molecular clock' was coined to describe the phenomenon, comparing the manner in which sequence changes occur to regular ticks of a clock. Is there really such a molecular clock?

New research has uncovered how a simple circadian clock network demonstrates advanced noise-filtering capabilities, enhancing ...

Microbial organisms dominate life on Earth, but tracing their early history and evolution is difficult because they rarely ...

A new genomic study has uncovered long-lost genetic diversity in mammoth lineages spanning over a million years, providing ...

Researchers have used machine learning, genomic data, fossils and the Earth’s geochemical history to create a timeline of bacterial evolution and oxygen adaptation.

The discovery that a group of cell-infecting bacteria lived roughly 2 billion years ago stirs a longstanding controversy around which came first: phagocytosis or mitochondria. A study of 19 ...

Increasing evidence highlights a bidirectional relationship between circadian disruption and hepatic pathophysiology, suggesting liver disease is both a consequence and a driver of circadian ...
