joining me now is dr sarah darwin. atural history museum and charles darwin's great—great granddaughter. thanks so much forjoining us, doctor darwin. can you just tell us what it feels like to be learning all this new information about your great—great—grandfather? the great-great-grandfather? the collection. _ great-great-grandfather? the collection, his _ great—great—grandfather? tie: collection, his library collection going online, is fascinating, because it gives us a window into his intellect, and also his emotional interests. and the breadth of his interest. for example, there is a paper on the turkey buzzard's ability to smell out prey, and invasive grasshoppers in the us, so it's an incredibly broad knowledge. i think what is relevant for us today is, it shows that although he was a recluse, he never went abroad again after his five year long for on the beagle, but he was part of virtual scientific knowledge community. it virtual scientific knowledge community-— community. it is quite an interesting _ community.
