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 how to compare DNA using percentages before watching two simulations from websites that show comparisons of DNA sequences between different organisms. Video 22 in a series of 31.

Instructional Ideas

• Best fits as a way to show scholars how to use DNA sequence comparison websites

Classroom Considerations

• Repeats parts of his video, titled Cladograms, in a different series
• Video should be shown after teaching cladograms
• This is the 6th video in a series of 31

Pros

• Video includes a link for a review worksheet
• Uses high-quality diagrams and photographs

Cons

• None
