DescriptionDarwin Tree 1837.png

Charles Darwin's 1837 sketch, his first diagram of an evolutionary tree from his First Notebook on Transmutation of Species (1837).

Interpretation of handwriting: "I think case must be, "that one generation should have as many living as now." To do this. And——to have as many species in same genus (as is) requires extinction . Thus between A + B the——immense gap of relation. C + B the "finest gradation." B+D rather greater distinction. Thus genera would be formed. Bearing relation" (next page begins) "to ancient types with several extinct forms"
