the theory of evolution
finches
Charles Darwin bred pigeons to test his theory of evolution through natural selection. By selectively breeding pigeons with specific traits, he was able to observe how variations in a population could be passed on to the next generation.

Charles Darwin discovered that finches in one place have different beaks in another place yet the same type of bird thus the theory of adaptation was born
The Galapagoes Finch is the bird on the Galagos Islands that Charles Darwin studies and formed the scientific theory of Evolution and Natural selection.

The theory of evolution was developed by Charles Darwin. He sailed on the HMAS Beagle to the Galapagos islands. He said that the finches were very similar, but had different beaks. This was probably so they didn't have to compete with other birds for food. They evolved by natural selection. This means that the bird with features best suited to the environment would breed and pass their characteristics on to the next generation. Birds not suited would die. This also happens with bacteria. Bacteria with a natural resistance to antibiotics would survive, breed and pass their genes onto the next generation.
Charles Darwin discovered plants and animals during his trip. He also saw that there were different mocking bird on each island he visted.
Darwin studied the finches of the Galapogas Islands about ten of them. Each had a unique beak for a different life-style centred about its food source.
CHARLES DARWIN ( 1809 - 1882 )WHAT EXACTLY DID CHARLES DARWIN DO?The theory of evolution was not new, in fact it had been around since the time of the ancient Greeks, but Charles Darwin is seen as the scientist who developed the modern theory of evolution and together with Alfred Russel Wallace proposed the principle of natural selection. Darwin eventually published his findings in,The Origin of the Species by Natural Selection.HOW DID CHARLES DARWIN FIND OUT ABOUT NATURAL SELECTION?Charles Darwin sailed from Plymouth on the 27 December 1831 on a journey that was to take him many thousands of miles. He sailed in a ship called the Beagle. The Beagle was not a big ship, it was only about 28 metres long and had to be home to 74 people for the whole voyage.TheBeagleat Sydney Harbour, 1841.

When they landed at Cape Verde he began to feel better, as he was able to go ashore and start noting, collecting, recording and observing the bird life, the natives, the plants and the landscape.

Charles Darwin changed Linnaeus's idea of classifying species according to their similarities and differences. Darwin's ideas made biologists begin to see classification as a way of describing evolutionary relationships.
Charles Bird King died on 1862-03-18.
