The Gene

This is a wonderful book in content, scope and writing style. It is the newest entry of the list of must read books like: “The Mismeasure of Man” (Stephen Jay Gould), “Thinking Fast and Slow” (Daniel Kahneman).

The author guides us through a historical journey of the gene and the genome. The writing style is vivid, clear and grounded by real examples, some deeply personal insights as the title expresses.

The book served both as an education, an insight into how and who does science and an appeal to deeper understanding of genetics  important implications for the future.
