Tree of Evolution
Segment of an illustration by Henry Holiday (cut by Joseph Swain) in Lewis Carroll's The Hunting of the Snark, 1876
The segment on the lower right side is Charles Darwin's Tree of Evolution, 1st notebook, page 36, 1837-1838. I learned, that Darwin did not keep his notebook secret after the publication of On the Origin of Species, but I do not know of any presentation of his sketch before 1876. Thus, the resemblance between the "weed" and Darwin's evolutionary tree sketch may be purely incidental.
