Rate variation and estimation of divergence times using strict and relaxed clocks

<p>Abstract</p> <p>Background</p> <p>Understanding causes of biological diversity may be greatly enhanced by knowledge of divergence times. Strict and relaxed clock models are used in Bayesian estimation of divergence times. We examined whether: i) strict clock models a...
