The Technology That Made It Possible

None of what we know about Denny would be possible without the revolutionary technology of ancient DNA sequencing.

This technology did not exist until very recently, in the timeframe of human history.

Understanding how it works helps appreciate how improbable — and how remarkable — the discovery of Denny actually was.

DNA is the molecule that carries the genetic information of living organisms.

In every cell of the body, a complete copy of the genome is stored — approximately 3 billion base pairs of genetic code, arranged in 23 pairs of chromosomes.
