Evidence of Wallace’s insight into natural selection prior to Darwin ‘s published papers.
Alfred Russel Wallace, Darwin’s unheralded codiscoverer of the theory of evolution by natural selection, found inspiration in the specimens he collected on his travels.
One day in 1855, in the teeming rainforests of Borneo, a bizarre-looking frog glided down from the canopy, its webbed feet spread, and landed in the scientific literature. For when a Chinese laborer working in the area caught the green-and-yellow creature, he took it to the British naturalist Alfred Russel Wallace, who was collecting specimens nearby.
Fascinated by his amphibious gift, Wallace painted a watercolor of the flying frog, then an unknown species.
