BIOLOGY - Evolution - Evidence for Natural Selection

The video explores the evolution of scientific thought from divine creation to the theory of evolution by natural selection. It highlights the role of fossil discoveries in challenging early beliefs and introduces Charles Darwin's contributions through his observations on the Galapagos Islands. Darwin's theory of natural selection is explained, along with supporting evidence from comparative anatomy and fossil records. The video also discusses modern molecular biology techniques that further validate evolutionary relationships, emphasizing the gradual changes leading to the emergence of new species.
