The most direct solution comes from analyses of ancient DNA recovered from fossils. Because the fossil specimens are independently dated by geologic methods, geneticists can use them to calibrate the molecular clocks for a given time period or population.
Can we date DNA?
Since genetic material (like DNA) decays rapidly, the molecular clock method cant date very old fossils. Its mainly useful for figuring out how long ago living species or populations shared a common ancestor, based on their DNA.
Is DNA dating accurate?

Can DNA find your soulmate?

What is the oldest proof of humans?

Is there a loyalty gene?
Men are more likely to be devoted and loyal husbands when they lack a particular variant of a gene that influences brain activity, researchers announced Monday - the first time that science has shown a direct link between a mans genes and his aptitude for monogamy.
Which gene is responsible for love?
