Among the reasons the finches make attractive subjects for research on evolution is that they live on oceanic islands. The Galapagos archipelago is a string of volcanoes that rise from the ocean floor 1000 km west of Ecuador. The islands have never been connected to the mainland, making it ...
The prevailing theory for the molecular basis of evolution involves genetic mutations that ultimately generate the heritable phenotypic variation on which natural selection acts. However, epigenetic transgenerational inheritance of phenotypic variation may also play an important role in evolutionary change. A...

The Grants had documented natural selection at work-the same process that, over many millennia, directed the evolution of the Galapagos' 14 unique finch species, all descended from a common ancestor that reached the islands a few million years ago. E Eight years later, heavy rains brought by...
's specimen collection helped him in the formulation of his theory of evolution, particularly the woodpecker finchLearn about the Galapagos finches, particularly the woodpecker finch (Camarhynchus pallidus); the birds played a key role in Charles Darwin's formulation of his theory of evolution....
all other land birds of oceanic islands in that there is more than one species on each island. Further, some of the species seem to grade into each other, and others are linked by freak specimens. Some workers have supposed that some quite peculiar method of evolution must have been ...
Charles Darwin, known as the father of evolution, set out on a voyage on theHMS Beagleas a young man. The ship sailed from England in late December 1831 with Charles Darwin aboard as the crew's naturalist. The voyage was to take the ship around South America with many stops along the ...
. darwin speculated that these sparrow-like birds came to the galapagos by the wind. thereafter, evolution took place, leading to different groups based on their different diets. at present, these finches are considered as emblems of evolution. frequently asked questions q1 who is charles darwin?
