2009 marked the 200th anniversary of Charles Darwin’s birth, and it seems fitting to mention here his diligent and invaluable use of field notes and diaries to record his thoughts, ideas and research. His original handwritten notebooks are lovingly preserved at Down House in the UK and much of his work is now freely available online. Generations of science historians have delighted in tracing the observations and lines of argument that eventually led to the publication of On the Origin of Species in 1859, and even today, reinterpretations of his original data and notes continue to reveal new insights. Charles
Darwin’s notebook-keeping habits owe much to his grandfather, Erasmus Darwin, who was a medical doctor as well as a prolific thinker and inventor. Erasmus belonged to an informal group of scientifically inclined gentlemen called “The Lunar Society,” widely recognized as a major catalyzing force behind the industrial and scientific revolutions of the 18th and 19th centuries. Darwin never knew his grandfather but was familiar with his works, especially his scientific ideas, which Erasmus recorded in his detailed and elaborately cross-referenced “commonplace book,” an early forebear of today’s modern lab notebook. Erasmus was so sophisticated with his record keeping and cross-referencing methodologies that we can be sure that as far back as the 18th century there were great scientists who understood the value of data mining, and the inadequacies of linear notebooks as a storage medium. Erasmus went to great lengths to try to help those thinkers that might one day read his work and attempt to build upon it, and as it turns out, this was extremely useful for his famous grandson.
Charles was profoundly influenced by his grandfather’s ideas about evolutionary biology. We know this because Charles Darwin’s copies of his grandfather’s publications still exist and many have been clearly and thoughtfully annotated in Charles's own hand. For example, next to a paragraph where Erasmus describes the way that birds’ beaks may have diversified as a result of the birds’ own endeavors to find food, Charles wrote:
"Lamarck, concisely forestalled by my grandfather"
Elsewhere, Erasmus describes farmers’ selective breeding of sheep with favorable traits as a way to to improve the flock. Charles writes "Good" showing his preference for the idea of selection rather than "modification by endeavor" as a mechanism for change.
This is a great example of what Isaac Newton called "standing on the shoulders of giants"; the process of learning from the records of those who have proceeded us, and building upon their work. The usefulness of this process in modern science should never be underestimated. Lev Vygotsky famously said that all learning is social, but how do we socially interact with people who are no longer living? The answer is that we can have a dialog of sorts with them by studying the work that they have left behind, and this dialog is most meaningful when the work they have left us is richly annotated in ways that help us understand their thought processes and ideas. Luckily for us, This process of rich annotation of thoughts and activities was very a deeply engrained habit in multiple generations of the Darwin family.
