the Grants and their assistants watched the struggle for survival among individuals in two species of small birds called Darwin's finches. The struggle is mainly about food -- different types of ...

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 ...

This morning came the talk that everyone had been waiting for - Princeton professors Peter and Rosemary Grant presented their 33-year project on the adaptive radiation of Darwin's finches on the ...

"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 ...

The Galápagos are a stretch of 13 major islands that live as much in myth as on the map—a finch-crowded Brigadoon where Darwin arrived in 1835 and began to make observations that eventually ...

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 ...

Darwin collected many animal specimens during the voyage of HMS Beagle (1831-1836). Among his best-known are the finches, of which he collected around 14 species from the Galápagos Islands. The birds ...

The finches in the above video were collected from the Galápagos Islands in 1835 by Charles Darwin and his colleagues during the second voyage of HMS Beagle (1831-1836). The different finch species on ...

Darwin did not have a great eureka moment on the Galapagos. He studied finches, tortoises and mockingbirds there, although not in enough detail to come to any great conclusions. But the steady ...

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.
