Darwin's Finches (Contingency Case)
The birds Darwin collected carelessly in 1835 and mislabeled, whose significance was revealed only through John
Gould's January 1837 taxonomic expertise—Gould's paradigm for how discovery depends on contingent collaboration.
The most famous birds in evolutionary biology nearly ended up in a dustbin. Charles Darwin collected specimens throughout the Galapagos in September-October 1835, but his attention was directed at geology—land rising from the sea, evidence of deep time. The birds were afterthought: shot, skinned, stored, but not labeled by island. He mixed specimens together. Several finches he identified incorrectly—a finch as a wren, a finch as a 'gross-beak.' The mess became revelation only through specific contingent encounter: Darwin gave bird specimens to John Gould, ornithologist at the Zoological Society of London, who examined them January 1837—more than a year after the Beagle returned. John Gould recognized that specimens from different islands were not varieties of one species but thirteen distinct species, each unknown to science, each exhibiting beak modifications correlating with different food sources. It was John Gould who showed Darwin what Darwin had been holding.
Stephen Jay Gould used this story repeatedly to demolish the myth of solitary genius experiencing flashes of insight. The
