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.
These are finches; Darwin noticed the variation on the Galapagos Islands and the Beagle's captain, Robert Fitzroy, was able to supply details about the various birds on each island. Darwin noticed that the finches had beaks adapted to different types of food; some strong to crack nuts, others fine to pick up seeds. Darwin asked a crucial question; if a single species of finch had arrived at the Galapagos, how could you end up with several different species? This was key to the idea of natural selection.
Swans are very territorial and fierce creatures. If they feel threatened they will flap their wings and honk as a warning. If the warning is not enough they will attack pecking and biting until the threat dies or goes away.
Yeast and cats are both organisms, both must meet the challenges of life.
Different internal organs of a chicken have different functions. The stomach and intestines help with digesting foods. The kidneys help with filtering blood and producing urine.
It's beak can drill into things and tweeze to reach other organisms. They can also eat many different foods

Their beaks were adapted to match the foods they ate.
Their beaks were adapted to match the foods they ate.
Through centuries of evolution, as discovered by Charles Darwin. Many animals adapt to suit their environment too, for example, polar bears are white to keep hidden in the snow, elephants have big ears to keep cool, and some birds have beaks that have adapted to eat specific foods.
their beakes were adaptationsrelated to the foods the finches ate
Bird beak sizes, many birds of the same species had different size beaks to pick up different size foods, thus suggesting they 'spontaneous' evolved
Generalists eat whatever comes along, while specialists are adapted to one or only a few different foods.
lots of different foods
Charles II.
different foods affect your body in different ways
Wrong. Because, "Foods", is not a word, and is not proper grammar.
Evolution was not discovered. It started as an explanation by Charles Darwin, in 1838, to explain the differences between animals on the mainland with animals he encountered on islands that were VERY similar with their mainland cousins but had modified traits and characteristics to allow them to survive in environments that their mainland cousins could not. Ex. A hummingbird on an island very similar to one on the nearby continent but with a very long curved beak to reach nectar in the bottom of a long necked flower that only grew on that island. Their short beaked cousins would have never reached the nectar. Charles Darwin admitted that he didn't know what mechanism existed that permitted these changes or govened their development. However, with the discovery of DNA, that mechanism was indeed discovered.
