Darwin explained the evolution of the different species of Galapagos finches through the process of natural selection. He observed that the finches had various beak shapes and sizes, which were adaptations to their specific diets and environments on the different islands. As the finches faced varying challenges and resource availability, those with beak shapes better suited for their particular food sources were more likely to survive and reproduce, leading to the divergence of species over time. This adaptive radiation illustrated how environmental factors can drive evolutionary change.

Speciation, which produces variety
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.
Geometric isolation of common ancestral species of finches has led to the development of 14 different species of finches in the Galapagos Island due to the concept of diversification.
No, evolution has created different species of finches on the Galapagos Islands. There are 15 different species that are found on the Galapagos islands.

The Galapagos Finches are best known for the difference in their beaks and also because they were Charles Darwin's inspiration for the Theory of Evolution.

The Galapagos finches only exist on the islands and inspired Charles Darwin. They implied that evolution occurs through natural selection.
Charles Darwin discover the finches in Galapagos in 1831. He noticed that the finches beaks were different compared to the finch's in Ecuador.
