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 ...

Nevertheless, the concept of molecular clock has been extremely influential in the field of molecular evolution. One of the most important ideas inspired by the concept of the molecular clock is ...

S. Kumar, S. Blair Hedges, "A molecular timescale for vertebrate evolution," Nature, 392:917-20, April 30, 1998. (Cited in more than 170 papers since publication) Thirty-five years ago, researchers ...

The changes and variations in genetic code that occur over time are referred to as "molecular evolution." The molecular evolution of an organism can be very different from its morphological (body ...

Mutation: it’s the raw material for evolution. That makes knowing the rate at which it occurs crucial to the study of evolutionary biology. Mutation rate figures into all kinds of calculations. For ...
