Biology is a conspicuous weak spot in my knowledge. My psychology education taught me a little about neurons, neurotransmitters, and brain structure. Beyond that, my main biological knowledge is trivia about platypi. So I read The Violinist’s Thumb less to learn about specific topics than to better understand how all these concepts of DNA, genes, cells and chromosomes related to each other.
The introduction sets up a powerful tension between the scientific value gained by understanding DNA and the fears thrown up by confronting our genetic building blocks. From there, we discover the parallel stories of Gregor Mendel and Friedrich Miescher, who first isolated genes and DNA. Using these building blocks of genes, Kean leads readers towards larger structures such as chromosomes, viruses, humans, and human cultures.
