I wanted to make a piece exploring how closely related we are to different species and to eachother, and had the idea of a bar-chart, containing the lines of the poem. The data was found in this article in National Geographic by Carl Zimmer about the percentage of genes we share with different species. The data originally came from gene sequencing at the European Bioinformatics Institute.
Whilst we are no longer surprised that we share 90% of our genes with chimpanzees (although even a few decades ago that would have seemed incredible to some), it is thought-provoking that we share nearly half our genes with fruit flies, and around a quarter with a grapevine! Given how complex these genes are, it is good evidence that we are all distantly related, with the degree of similarity correlating to our proximity on the family tree.
The percentages in the article’s infographic gave me the idea of using a bar chart, with the lengths of the bars dictating the size of the lines. I worked through several drafts omitting some species until I found a combination that used most of them (sorry, yeast!). I decided to pick out the letters of the nucleotide bases A, T, G and C in a different colour, just for extra geekiness.
The idea of a writing metaphor emerged from consideration of the letters, and the ‘words’ (genes) they made up, with the constant revisions and deletions over time. Poetry too is about the arrangement of a limited number of letters and words, sometimes through happy accident.
