What is a common method to estimate evolutionary divergence?

Applying molecular clock techniques is a widely accepted method for estimating evolutionary divergence because it utilizes the concept that mutations accumulate at roughly constant rates over time in the DNA sequences of organisms. By comparing genetic differences between species, scientists can infer the timing of their evolutionary splits. This method allows for quantifiable estimates of when lineages diverged, giving insights into the timing of evolutionary events.

Molecular clock techniques can be cross-referenced with fossil records to calibrate the molecular data further, effectively combining both molecular and paleontological evidence for more robust estimates. This integration provides a clearer picture of the evolutionary history and relationships among species, highlighting the power of molecular data in evolutionary biology.
