What Are Molecular Clocks Based On? Molecular clocks are based on two key biological processes that are the source of all heritable variation: mutation and recombination. Mutations are changes to the letters of DNA’s genetic code – for instance, a nucleotide Guanine (G) becomes a Thymine (T). What assumptions are molecular clocks based on? The

What Are The Characteristics Of A Good Molecular Clock? An ideal molecular clock has a number of features: rate constancy through time, rate homogeneity across lineages, taxonomic breadth and applicability, and accessibility of the data. Characters that have evolved at a relatively constant rate are the most suitable for molecular clocks. What are molecular clocks
