1. If you ever get the chance to visit Down House, I would highly recommend it. You can do the Darwin sandwalk.

2. Legendary man.

3. Darwin didn’t invent the idea of the tree of life. Treelike hierarchical representations of species went back at least to Linnaeus, a century before Darwin. That’s where kingdom, phylum, order, class, genus, species etc comes from. Those are the layers of the hierarchy. Darwin’s contribution was the idea of natural selection.
