Meselson-Stahl Experiment
Paul Andersen explains how the Meselson-Stahl experiment was used to prove that DNA copied itself through a semi-conservative process. They grew E. coli in a medium containing heavy nitrogen (N-15). They then added the E. coli to a...

Genetic Drift
Paul Andersen describes genetic drift as a mechanism for evolutionary change. A population genetics simulator is used to show the importance of large population size in neutralizing random change. The near extinction of the northern...

Comparing DNA Sequences
Through the mapping of the DNA of songbirds, scientists have discovered a gene network common among the species. In the video, scholars explore the comparison of DNA sequences, then attempt to place DNA sequences on a cladogram. They see...

Scientific Evidence for Evolution
Humans share about 50% of their genes with a banana. In the video, scholars analyze the scientific evidence for evolution. The instructor spends time discussing Darwin and biogeography, fossils, and homologous structures. Scholars then...
