Question

How are molecular clocks calibrated in actual time?

Answer 1

However, most phylogenies require that the molecular clock be calibratedagainst independent evidence about dates, such as the fossil record. There are two general methods forcalibrating the molecular clock using fossil data: node calibration and tipcalibration.
