Ancient DNA in Plain English: How Paleogenomics Reconstructs the Genomes of Neanderthals, Denisovans, and Lost Human Lineages from Soil and Bone

A plain-English guide to paleogenomics that shows you how broken molecules from Siberian caves and Tibetan jaws are rewriting the story of human origins, with an evidence framework you can use the next time a headline promises to explain who you really are.

The story of who we are is written in broken pieces of molecule, and this plain-language guide walks you through what paleogenomics has actually shown, what is being demonstrated now, what is still in research, and what remains an open question for the next decade of work. Every strong claim in the book traces back to a specific study, and every chapter separates what has been proven from what is still under active investigation, so you can bring the same discipline to any headline you meet about Siberian caves, Tibetan jaws, Icelandic ancestry archives, or a wearable ancestry test someone hands you. The result is a working map, told without hype, of a field that is remaking human history one fragment at a time.
Inside this book, readers will learn how to: How fragment length and cytosine deamination turn broken molecules into a datable age stamp Why the petrous temporal bone yields more endogenous DNA than any other skeletal tissue How cave sediment DNA reveals a population when no identifiable bone survives What the Denisova finger bone and Xiahe jaw tell us about a group named across two continents How ghost lineage inference describes an unsampled population from the shape it leaves behind What the EPAS1 story actually shows about ancient contact and modern altitude physiology Why community partnership and museum ethics are built into the research protocol, not added later Written for students, museum professionals, clinicians, and curious readers, this book turns a fashionable field into a working map. You will finish with a vocabulary, an evidence framework, and the confidence to ask better questions about ancestry and origins headlines. Along the way, a fictional team at the Paleogenome Research Institute shows how a research finding becomes a decision a real lab can live with, so the chemistry never feels far from the deep past you are trying to reconstruct.
