Do dinosaurs prove evolution?
For millions of years dinosaurs roamed and dominated the planet. Then 65 million years ago, they went extinct. In fact, over 90% of species that have lived are now extinct. The change in species over time is evolution, the focus of the lessons in this chapter.
Evolution focuses on past life forms and how they turned into present life forms. The history of life on Earth demonstrates how the first cells formed, turned into simple life forms, and then became more complex plants and animals. The studies of Charles Darwin have reshaped and influenced all aspects of biology. The myriad evidence of evolution demonstrates the importance of the theory of evolution by natural selection. Lastly, the current focus on evolution demonstrates that evolution is a continuous and ongoing process that continues today.
