The same DNA technology that allows the analysis of a hair or tiny blood spot at a crime scene also enables sequencing the DNA of a bone fragment from a Neanderthal skeleton. Comparing the DNA sequences of different samples and comparing the frequency of specific genetic variants in different populations is a critical part of both forensic and evolutionary investigations. These two fields share a common goal: solving historical mysteries. The book discusses the intrinsic human curiosity about our origins and the desire to solve crimes and seek justice and how the recent emergence of DNA analysis has transformed our ability to address these universal human aspirations. The unifying theme of t...
