Exploring Evidence of Common Ancestry and Diversity

Paul Anderson discusses the evidence of common ancestry and diversity, starting with Darwin's ideas and the lack of molecular evidence during his time. The video explores fossil evidence, molecular evidence, and the use of DNA to understand evolutionary relationships. It also outlines a teaching progression from elementary to high school, emphasizing the importance of fossils, sedimentary rocks, and molecular evidence in understanding the history of life on Earth.
