Evidence of Common Ancestry and Diversity
In this video Paul Andersen describes several types of evidence for common ancestry. This evidence is contained in the fossils, embryos and molecules of living organisms. Even though life on our planet is incredibly diverse there are common threads that run through everything. This idea was most elegantly put forward by Charles Darwin before much of this evidence was gathered. A teaching progression K-12 is also included.
