1 gen 1837 anni - Darwin starts secret notebooks (1837)
Descrizione:
As experts sort through his Beagle collections, Darwin feels compelled to pursue what he knows is a radical -- even dangerous -- idea. His Galapagos birds, in particular, seem to point out that new species can evolve over time from a common ancestor. Darwin labels on of his secret notebooks "Transmutation of Species," and in it he sketcbes his first "tree of life."
