How do you know that finches' beak depth is heritable? You can see from Figure 2 that there is a correlation between the parents' and offsprings' beak size. How did the finch population change ...

David Lack's classic work on the finches of the Galapagos Islands (Darwin's Finches) was first published in 1947; few books have had such a great impact on evolutionary biology, indeed it is still one ...
Scientists long after Darwin spent years trying to understand the process that had created so many types of finches that differed mainly in the size and shape of their beaks. Most recently ...
"In my very first publication on the finches, back in 2001, I showed that changes in the beaks of Darwin's finches lead to changes in the songs they sing, and I speculated that, because Darwin's ...
Darwin's Finches These drab but famous little birds of the Galapagos Islands are a living case study in evolution. Isolated in the South Pacific, they have developed 14 species from a common ancestor ...
As the legend goes, Darwin sailed as ship's naturalist on the Beagle, visited the Galápagos archipelago in the eastern Pacific Ocean, and there beheld giant tortoises and finches. The finches ...
Despite the fact that quantum mechanics rules the world at length scales many orders of magnitude below the size of Darwin's finches or Mendel's pea plants, quantum mechanics has a profound effect ...
On the Galapagos Islands, Darwin observed how the beaks of finches differed. Only later, would he realise why this happened. Today, we can see how the different beaks serve different purposes.
To understand the story of evolution—both its narrative and its mechanism—modern Darwins don't have to guess. They consult genetic scripture. Consider, for instance, the famous finches of the ...
