Molekyylikellot
Molekyylikellot, or molecular clocks, are theoretical tools used in biology and evolutionary studies to estimate the time of divergence between species or the rate of evolutionary change. The concept is based on the idea that certain genetic mutations accumulate at a relatively constant rate over time, allowing researchers to infer evolutionary relationships and timelines.
The foundational principle of molecular clocks relies on the assumption that neutral mutations—those that do not
Early applications of molecular clocks in the mid-20th century were based on allozymes, protein variants that
Criticisms of molecular clocks include the assumption of a constant mutation rate, which may not hold true
