The shifting songs of Darwin’s finches have given new insight into processes that shape the course of evolution, preventing newly forked branches on life’s tree from growing back together.

They say that hindsight is 20/20, and though the theory of ecological speciation—which holds that new species emerge in ...

The group turned to a well-studied species — the so-called Darwin’s Finches, named because the famous scientist, Charles Darwin, observed them on the Galapagos Islands. In a study 25 years ago, ...

These bird species, along with other animals on the islands, inspired Charles Darwin’s theory of evolution and, 150 years later, allowed Schluter to demonstrate that Darwin’s theories about ...

Darwin’s finches helped inspire Darwin’s theory of evolution by natural selection, as their different beak shapes across different Galápagos islands demonstrated how species could adapt to ...

The finches that call Ecuador’s Galápagos Islands home are biological rock stars, as they provided a key piece of evidence for Charles Darwin’s theory of evolution.One reason for this is how ...

Adaptive Radiation: Darwin's Finches: When Charles Darwin stepped ashore on the Galapagos Islands in September 1835, it was the start of five weeks that would change the world of science, ...

Their study uses one of the largest genomic datasets ever produced for a wild animal, comprising nearly 4,000 Darwin’s finches, to reveal the genetic basis of adaptation in this iconic group. This ...

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 ...

On the Galapagos Islands, a ground finch that usually munched on small, soft seeds was forced, during a drought, to eat harder, larger ones. Within the space of a few generations, the bird evolved ...
