Why do textbooks claim that beak changes in Galapagos finches during a severe drought can explain the origin of species by natural selection — even though the changes were reversed after the drought ended, and no net evolution occurred?

"Our data show that beak morphology is affected by many genes as is the case for most biological traits," said Lamichhaney, who also was first author of the 2015 paper.

Some experts are skeptical of the finding, arguing that beak evolution was too slow and messy a process to be explained by one gene and a couple of proteins.

Lack (1947) showed that beak sizes of species of Darwin's ground finches tend to be more different from one another when they occur on the same Galápagos island than when they occur on different islands.

We base this hypothesis on the discovery that beaks play a functional role in song production in songbirds.

Field studies have shown that beaks evolve by natural selection in response to variation in local ecological conditions.

The work highlights that beaks develop very differently from snouts, using a different set of genes, says Michael Benton of Bristol University in the UK.
