Darwin's ant conundrum (IMAGE)
Caption
Even Charles Darwin threw his hands up in the air when trying to explain one species of dulotic ant in his “Origin of the Species” book. “By what steps the instinct of F. sanguinea originated I will not pretend to conjecture,” wrote Darwin. This is his original sketch of a parasitic Formica ant raiding the pupae in a rival nest.
