We would also like to dedicate this study to those who have inspired us deeply by their science, art, and heroism: Alfred Russel Wallace, for his biogeography and natural history; Charles Michener and John Lawrence, for their comprehensive work on their favourite groups of insects (bees and beetles, respectively); Ernst Shackleton, for his endur- ing expedition to Antarctica; and Jerry Garcia and David Lynch for their contributions to art, music, and culture.
