About this Product
Charles Darwin's first ever sketch of a tree of life, in the shape of an actual tree, with finches perched on the branches. Each branch and minute detail of Darwin's original drawing is represented, and each finch represents the A, B, C and D marks on his sketch. The sketch appeared in his private notebook (“Notebook B on the transmutation of species,” 1837–1838).
From a side view, the shape of the tree matches perfectly with Darwin's drawing (look at the images for a comparison). If you look carefully, you'll notice that each finch is slightly different, and the more apart they are from each other in the evolutionary tree, the more distinct the differences are.
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."
