Charles Darwin & Evolution
Darwin's Theory of Evolution
Darwin's theory was that all life is related and has come from a common ancestor. Complex creatures evolve from more simple ones over time in a natural process. As mutations occur within an organism's genetic code, the best ones will survive. This is known as Natural Selection.
Evolution Primer #4: How Does Evolution Really Work?
Finches and Darwin on the Galapagos Isands
In 1831, Charles Darwin traveled the world studying plants and animals. He went to South America and the Galapagos Islands and found that the finches were resembling a mainland bird. Darwin asked a question: why did the Galapagos species look a lot like organisms on the South American coast Line? These make his theory
Natural selection and Evolution
The unique Galapagos species of Finch looked identical, except for the different types of becks change them. Comparing on their food sources their becks would adapt to their surroundings. The Warbler Finch eats different types of insects and seeds, The Tree Finch has a wider beck so it eats different types of bigger nuts compared to the ground finch which eats the smaller nuts because its beck is the Biggest
Observation Comes to Conclusion
The observations of the finches lead Darwin to theorize that all different organisms that has been formed from one single organism. Over a long period of time the accumulated modification make each species unique.
