Evolution

Explore Charles Darwin's groundbreaking ideas on evolution as presented in "On the Origin of Species." Discover the concept of "Tree Thinking," which illustrates the relationships among species as a complex tree of life. Additionally, learn about the principle of natural selection, the mechanism through which species adapt and evolve over time. This foundational theory of evolution is supported by geological, fossil, and genetic evidence, including homologous structures and vestigial traits. Join us in understanding the science behind the diversity of life on Earth.
