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 ...

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

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?

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

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

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

“In each of our cells, we have genes that form the molecular circadian clock,” Peek said. “These clock genes encode a set of transcription factors that regulate many processes throughout the ...

One method Vinther uses is called a molecular clock. He takes the DNA from modern organisms and based on DNA mutation rates Vinther uses a computer model to calculate when these organisms first ...

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