The discovery of DNA changed the way scientists viewed the universe because it provided a mechanism for evolution. Before the discovery of DNA, scientists believed that all species were created at the same time by God and had remained unchanged since then. With the discovery of DNA, scientists realized that organisms could change over time through mutations in their genetic code, allowing them to adapt to changing environments. This led to the theory of evolution, which is still widely accepted today.
