Can you date DNA?
Analyzing DNA from present-day and ancient genomes provides a complementary approach for dating evolutionary events. Because certain genetic changes occur at a steady rate per generation, they provide an estimate of the time elapsed.
Can you tell how old a person is by their DNA?
To keep important bits of DNA from disappearing, we have long stretches of DNA at each end called telomeres. Scientists used to think if they could measure the length of a person’s telomere, they would be able to tell their age. After all, the more times a cell divides, the shorter its DNA will be.
