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 ...

One method Vinther uses is called a molecular clock. He takes the DNA from modern organisms and based on DNA mutation ... Vinther has examined the structure of feathers and the origins of iridescence ...

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 ...
