A major breakthrough in paleontology has shifted our understanding of the woolly mammoth’s presence in North America. A ...

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?

Microbial organisms dominate life on Earth, but tracing their early history and evolution is difficult because they rarely fossilize. Determining when exactly a particular group of microbes first ...

Within the scope of this review we summarized current knowledge on the circadian clock in oral tissues with the aim to raise awareness for findings that are relevant for the main fields of dental ...

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

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 ...
