About this Product
Charles Darwin's first ever sketch of a tree of life printed in solid silver. Each branch and minute detail of Darwin's original drawing is represented. The sketch appeared in his private notebook (“Notebook B on the transmutation of species,” 1837–1838).
Chain not included, but a chain can easily be attached if you want to wear it. The metals come in a soft, black velvet bag.
A great gift for taxonomists, biologists, skeptics, humanists, atheists, lovers of nature and rational thought. Also a great gift for creationists, seriously, they'll love it! :)
The sketchy text on the same page of Darwin's notebook reads: "I think ... Case must be that one generation then should be as many living as now. To do this and to have many species in same genus (as is) requires extinction. Thus between A & B immense gap of relation. C & B the finest gradation, B & D rather greater distinction. Thus genera would be formed.—bearing relation."
