Within a population many individual do not survive
Charles Darwin found that finches on the Galapagos Islands had variations in their beak shapes that were well-suited to the different types of food available on each island. This observation led him to develop his theory of natural selection as a driving force of evolution.
Charles Darwin developed the hypothesis that the Galapagos finches evolved from a common ancestor that arrived on the islands and diversified based on the different environments and food sources available on each island. This observation helped support his theory of evolution by natural selection.
