In May 1856, Darwin began writing up his 'species sketch’ in earnest. During this period, his working life was completely dominated by the preparation of his 'Big Book', which was to be called Natural selection. Using letters are the main source for much of his research he amassed data, carried out breeding experiments, and struggled with statistical analysis. Several of his experiments: seeds would not germinate; beans failed to cross; newly-hatched molluscs refused to do what he hoped. Most significant in terms of Darwin’s future, however, was the beginning of his correspondence with Alfred Russel Wallace.

Although Darwin worried about the effect of the quarrels on public perceptions, his theory was gathering support in influential scientific circles. He struggled with leaf angles, fractions, diagrams, and shoot dissections.
