It's hard to imagine spending a single night here, much less two months, but that's exactly what British naturalist Alfred Russel Wallace did in 1860 while studying birds-of-paradise, an aptly named group of about 40 species whose lavish plumage and elaborate courtship dances helped inform early research on evolution.
Hales shifts the figure of Darwin from its usual role as the organizing centre of attention to show Darwin in dialogue with Malthus, Herbert Spencer, and Alfred Russel Wallace. Hale describes how Darwin's rejection of Lamarck--and with it the radical politics often attached to the theory of acquired characteristics--facilitated the acceptance of On the Origin of Species (London, 1859) by placing it within the mainstream of Whig politics.
Indeed evolution by natural selection is a promising case for a counterfactual study because it is a famous case of "simultaneous discovery." Alfred Russel Wallace came up with something similar in a malarial fever dream, impelling Darwin to publish sooner than he would have liked.
