A molecular clock is a method used in evolutionary biology to estimate the timing of evolutionary events. It assumes that genetic mutations accumulate at a relatively constant rate over time. By comparing DNA, RNA, or protein sequences between different species, scientists can determine the number of mutations and infer the time since their last common ancestor. Molecular clocks are calibrated using known fossil records or historical events, providing a timeline for evolutionary divergence. This tool is essential for understanding species evolution, phylogenetic relationships, and the pace of genetic change over geological time scales. This is an MCQ on Molecular Clock with Answers.
